Title: The Great Flood 2021
Post by: CohoJake on November 15, 2021, 08:37:19 AM
It looks like this is shaping up to be a possible record flood of the Nooksack and Skagit rivers. Rod, I'd be very curious if Tamihi bridge looks like it did in 2006. Rivers don't respect boundaries right now - the Nooksack is flooding into the Sumas drainage to the north and the Samish drainage to the south, which I think is combining with the Skagit as well. When these big flood events occur, I am always curious what is going to happen to our favorite fishing spots and what new ones will develop. I fear this also means the pink salmon return for 2023 will be dismal, as the eggs in gravel are now being washed away or buried in mud. Everybody remember - don't drive across flooded roads, this is how the majority of casualties in floods occur. That said, if anyone has interesting pictures of high water to share from where they are, I'd love to see them.

How were the pink salmon runs following the past big floods? If they were decent after those floods, then there's hope.

I think a good portion of the pinks spawn in mainstem of the fraser so it should be okay.

Fraser is up 2 meters in hope so..... don’t know about that . Saw coquihalla hiway literally gone west bound at othello as well. I can’t remember the last time the vedder was this high maybe that big event around 2006ish I believe . I know the resident fish trout and whitefish seemed to take  a serious hit as well.  It was almost coming back the last couple seasons, too bad.  Like dave said these side channel man made refuges are the only saving grace we have at this point . Only 3/4 smaller Natural spots I can think Of mid river from teskies to Osborn . I Wonder what the river  looks like in the Centennial spawning channels at this height . Hopefully all is well up there .

Sigh... the last time I remember the Vedder being this high I made a bit of a prediction that it will destroy a lot of the spawned chum eggs and this was back in 2016-2017 I believe. Chris had a video of a giant log jam moving down river and that was very concerning for me.

As for other systems... Stave is so high that the bridge that goes across the spawning channel is covered in water and the floats at the damn (The big yellow ones) have broken free and are strewn across the main channel.

Does anyone one know how it impacted salmon back when it flooded in 2006? Im wondering what the salmon numbers trend was like after 2006 ?
Title: Re: The Great Flood 2021
Post by: geomorphin on November 15, 2021, 06:26:55 PM
It looks pretty gnarly out there but there's been lots of floods bigger than this since 1970 and the fish have found ways in the past.
Here are the max flows per year here: https://imgur.com/ln0WS5z  (Most of these are in the fall as well) 

This is why it's important to not cut off all the back/side channels since it's critical salmon habitat.  We have a nasty habit of wanting to straighten out rivers and lock them into place. Floods like this are important reminders for why rivers must be allowed to move laterally. 
Title: Re: The Great Flood 2021
Post by: RalphH on November 15, 2021, 07:04:46 PM
certainly true that the salmon do bounce back from these big flood events. It may have an effect at the end of the brood cycle when the adults come back but nature has many compensating features that allow for quick rebuilding of the population. I can't remember what year it was but there was a year maybe 20+ years ago with a big flood and it was thought to have all but wiped out the pink spawn. fishing was closed in the following return but 2 years after that there was another strong return. Some of that may be do to fish from the Fraser that moved into the V-C to spawn, hard to say but the dip didn't last long.

Going back to that real estate video posted earlier, the first comment left in there mentions the names of the owners. I don't think the house was ever sold. This very likely is someone's entire saving, dream at one point but shattered by the ongoing harrassment. Nobody should be pleased with the outcome.

Edit: Just looked up the names. It's young couple with a little kid. House was listed for $1.5 million. I really hope this does not mean a total financial loss for the family.

According to FVRD, the Wilson Road dyke is 900m long and protects 20 properties and the Chilliwack River Road. While the photo shows one property, there are also many other families and homes impacted.

It’s hard to imagine the forces at play of almost an additional 3 metres of water and debris colliding head on with that massive rip rap dyke.

I very much admired Quebec Premier LeGault's comment 1n 2019 that flood victims in the Gatineau area should move out of the flood plain where they had recently been flooded out twice in 2 years. To that end they offered no more than $100g for flood relief but $200g if they agreed to move. IMO Cities, Regional governments etc have been irresponsible in developing flood plain areas as have individuals and business in moving there. Invariably senior governments end up footing much of the bill for flood relief damage as people are either under insured or insurance companies cry the blues about defaulting The apparent increase in extreme weather events will accelerate this problem.

I have a background in water damage restoration and this is beyond the scope of anything I've ever seen. There's going to be a ton of remediation work and just on the structural drying alone and I highly doubt there's enough equipment or qualified technicians to handle this. If the buildings don't get serviced in the appropriate time window, mould will be an issue as long as there's a food source for it to feed on and produce mycotoxins. The aftermath is going to be bad too. Between the toxicity of what we were dealing with and the 20 hour shifts, I pulled the plug and started a business.

Everybody should prepare for a steep rise in your home insurance premiums whether or not you got hit. The insurance companies like to share the pain.

B.C. limits gas purchases to 30L per visit in southern region as flooding impacts supply

B.C.’s public safety minister has enlisted two new provincial orders amid concerns of gas shortages in the province due to the devestating floods that hit southern B.C. this week.

In a news conference Friday (Nov. 19), Public Safety Minister Mike Farnworth announced that non-essential travel will be restricted on all highways impacted by washouts.

This means that highways impacted will be only open to those travelling to get home, as well as commercial and emergency vehicles.

Highways include:

Highway 99: from the junction of Highway 99 and Lillooet River Road to the BC Hydro Seton Lake Campsite access in Lillooet. Only passenger vehicles and commercial vehicles up to 14,500 kilograms will be permitted.
Highway 3: from the junction of Highway 5 and Highway 3 in Hope to the west entrance to Princeton from Highway 3.
Highway 7: from the junction of Highway 7 and Highway 9 in Agassiz to the junction of Highway 7 and Highway 1 in Hope.

Meanwhile, the public will be limited to purchasing 30 litres of gas per visit to gas stations in southwest B.C., Vancouver Island and Sunshine Coast.

Farnworth said there is a reduced but steady supply of gas and province is working with the feds to import gasoline in new ways.

“Carpool, share with a friend, walk, use alternative methods,” Farnworth said, adding to be kind to others.

In light of the low return of chum and their subsequent big loss of eggs in the rivers by this huge flood,  should the hatcheries increase their chum egg production if they have more chum in the hatchery than their original target. That will help make up for the loss of eggs in the river.

At least one hatchery will be increasing production but I would like to see much more emphasis on hatchery chum production from all coastal hatcheries. A very cheap bang for the buck ecosystem boost, imo.

https://globalnews.ca/news/8385471/repairs-coquihalla-highway-reopening-timeline/

More like a year...
Considering Coquihalla winter weather, it's going to be months just getting: new engineering, construction plans drawn and approved, and the backfill, foundations and bridge piers secured.  In addition to that there's the pre-cast concrete beams for the bridge. 

I personally know an executive in the pre-cast concrete industry and those big bridges that we commonly see in the washout pictures will require at least 30 huge beams for each direction.  Even when they do have blueprints and specifications they then need to fabricate molds, then pre-load the mold with tensioning cables, pour the concrete, let it cure enough for the huge beam to be pulled from the mold, then re-condition & re-set the mold to pour beam #2....  That can take a few days per pour.  Each beam has to additionally cure at the plant for 28 days before it can be transported to the bridge site.  Multiply that all out for 60 beams.  (when they originally built the highway the plants had designs a year befor the beams were needed)  All that time only gets the beams to the site, there still needs to be: a roadway poured on top, railings, safety barriers,.....

There's very few plants that can make those beams and they're all presently in the midst of contracts for building beams and panels on other projects with timelines.  So even if there were blueprints and spec available soon it could be months before they can even start the first beam.

Seems like it would be very challenging to build permanent replacement roadway with temporary structures nearby.
The builders of the actual replacement structures ,are going to need to create, or re-open, temporary gravel extraction pits and works yards as well as at least one each of concrete and asphault plants.

The pricetage for remediating that rainstorm damage is going to make the total COVID related pricetag look small :'( :'(

the New Normal Climate is bad enough now at 1.1 degrees above pre-industrial, and some world leaders are willing to not stop at +1.5 (which IMHO will be worse than today) but they're willing to target +2 or +2-1/2 degrees. :( :( :(

Nice graph there, looks like 2006 was worst, Good to hear that Salmon does bounce back quickly! Certainly got to know the critical importance of these side channels

the 2 high water discharge events on the graph were in 2003 and 2006 or  2007. Looks like 2003 was the big largest followed by another major flood within 3 or 4 years.

Route out of southern B.C. closed again due to washout

A main route out of southern British Columbia is closed again due to a washout, officials say.

Highway 3 is closed in both directions between Hope and Princeton. An assessment is in progress, but there is currently no estimated time of reopening.

The route also known as Crowsnest Highway had only just reopened.

This made me curious about previous high water events as I sorta recall some big occurrences, but no particular details. Downloaded some historical annual daily max data from wateroffice.ec.gc.ca to see. The data goes back somewhat further, but I limited it to ~1950

(https://imgur.com/mrUcL2u.jpg)

Based on last week's peak flow of ~488 m3/s it looked like it was exceeded three times in the last 70ish years though it did get close at least a handful of other times. 2003 was indeed the largest at over 600 m3/s, an additional 25% more flow than this weeks event.

An acquaintance recently mentioned he remembers a pretty significant flood in Chilliwack from when he lived there (much) younger, and guessed it could have been in the 70's. '75 and '80 had big events which could very well be what he experienced...

edit: updated to show which annual max flows occurred in the spring/summer (Apr-Sep) vs fall/winter (Oct-Mar). Presumably from freshet vs rainfall.

I worry about my favorite fishing spots too! Will they have disappeared? Is everything now filled in? Do I have to look for new places to fish? There are places I fished for 30+ years, beautiful glides and tail outs where winter time cutthroat sipped emergers from the surface. They are gone & replaced with deep fast water. So far I haven't found anything comparable. :'(

Although I didn't have 30 years there like your spots, I knew it like the back of my hand.  Yes there's the challenge of learning it all over again, adapting and exploring, but sometimes you just want the comfort of a familiar old friend.

I left cultus lake the Sunday afternoon before things went for a real s#!t, just before the main road into cultus washed out. In 30 plus years fishing the vedder I have never seen so much water running down that river as that day. I can’t imagine what the lower river looks like now. A lot of people’s favourite fishing spots will be gone. Mid to lower always changes some every year and I always enjoyed looking for new steelhead water every winter but I think not this year.  My daughter and I will instead be looking to help out the community we call home for six months of every year. People have lost a lot out there but that doesn’t mean it’s selfish or bad to reflect on favourite fishing spots lost.

Clarki, as I said we left just before it got super ugly but it had been raining hard all night and it was blowing like crazy. We were watching the trees and thinking it’s time to go ! Decided to avoid the highway and take the backroads through all the farmland to get home to Richmond. Even at that time all the big ditches were not only full but were flowing like fast moving creeks. We are part timers at cultus, just keep our trailer there April to September but we have many friends who live there full time and some who have cabins there. I have gotten many pictures and videos from our friends who live there. Some frightening stuff. The video link you posted is the beach in front of the place we park our trailer. Can’t imagine what that will look like in the spring when and if we are allowed to return. Have a friend at lindell beach who lives between watt creek and frosst creek and his house survived while many of his neighbours places were not so lucky. I also saw the previous path of destruction at watt creek that you mentioned. Scary. I’m sure it looks much worse now. Sad.

Since our lives are relatively, so short, we tend to think our common landscape features change little over time. Who would think for example, that the Nooksack River was once a tributary of the Fraser river, or that 10,000 or so years ago almost none of our favorite fishing spots in the Valley and LM existed. They would have been covered by hundreds of feet of seawater. The valley up to Hope was a saltwater sound. Both Harrison and Pitt lakes were not lakes but saltwater inlets of the Salish Sea.

There are 3 spots on the Fraser I used to fish for cutthroat in the winter and spring which basically disappeared, became unfishable, mostly due not to floods, but to flood remediation. By gravel mining and riprap structures that both changed the river course and left them all but inaccessible. These days the riprap is made using boulders that are the size of small cars. A couple of years ago on my return to one place I found a sloped field of riprap about 40 yards wide, up to six feet high with chasms as deep and if I slipped, wide enough to swallow my leg.  It terminated in deep water where once there was a gravel beach.

I went back the next year and most of the gaps between the riprap were filled with silt and a muddy beach skirted the edge. In one season of flooding the river had all but covered that riprap.

Yes, not only the Nooksack, but also the Upper Skagit used to flow into the Fraser. I'm fascinated by the places where these rivers intersect in high water. The Nooksack and Johnson Creek, which flows into the Sumas River, are only separated by low farm land, so it isn't hard for them to combine. Same for the South Fork of the Nooksack and the Samish River, which flow in opposite directions in the same valley. I wonder what hopping points there are like this with BC rivers. It also reminds me of the special places in Yellowstone National Park where Snake River tributaries can flow either way over the continental divide, meaning you have cutthroat that are actually east of the Rocky Mountains. I have also thought that if the Chilliwack native spring chinook really are extirpated, the North Fork Nooksack stock may be genetically similar enough to re-establish that run, since these rivers have meandered and connected to a certain degree over recent geologic time.

This will eventually be okay if the gravel stays in place but i'm sure were going to see a big push to mine it in the name of flood protection.

the other thing will be the 2022 freshet, there is a huge amount of mud and trees sitting at the sides of banks right now waiting for another high water event.

may explain the sudden appearance of bass in the Fraser Valley in the 80s and 90s. Some have since certainly been moved by the bucket brigade but some US watersheds aren't as separated from Canadian waters as we'd like to believe.

They aren't native to Washington waters, so no.

I know there are LMB in the Nooksack watershed downstream of Lynden, in Wiser Lake, but I don't know of any upstream. However, as I have speculated before, I think Boundary (Judson) lake likely overflows into the Sumas system during floods, and that is where I caught my first LMB.

genetically interior Fraser coho and steelhead are more closely related to equivalent stocks in the Columbia than those in the lower Fraser. The upper part of the Thompson system first flowed east into the Columbia as at the end of the Pleistocene, the Columbia basin was free of glaciers before the current Fraser basin and South Coast mountains were so it's assumed the Columbia was the source of the first salmonid colonizers of BC's interior.

Recently took a look at the shocking video of the devastation along Highway 8 between Merrit and Spences Bridge. So many chunks of highway are washed out it will takes years to replace if ever. Hard to believe that a stretch of highway that has been around for nearly a century was wiped out in a couple of days. Feel bad for the FN , ranchers and others who lived along Highway 8

I don't know how I missed it earlier, this is amazing! Thanks for the link.
Playing with Google Earth tonight... I never realized how closely linked the Chilliwack and Nooksak Rivers are.

The Chilliwack's headwaters are on the north flank of Ruth Mountain, and the Ruth Glacier.

A tributary of the Nooksak, Ruth Creek, also flows off the same glacier. The only thing separating the Nooksak and Chilliwack watersheds is narrow ridge that runs north of Ruth Mountain.

Since our lives are relatively, so short, we tend to think our common landscape features change little over time. Who would think for example, that the Nooksack River was once a tributary of the Fraser river, or that 10,000 or so years ago almost none of our favorite fishing spots in the Valley and LM existed. They would have been covered by hundreds of feet of seawater. The valley up to Hope was a saltwater sound. Both Harrison and Pitt lakes were not lakes but saltwater inlets of the Salish Sea.


The whole area from the north shore south to Bellingham and east to Agassiz or Hope used to be the Fraser river delta.  12,000 years ago it was covered in Ice.  As the >1km thick glaciers retreated, and the Fraser had a much higher water flow, the glaciers ground down the coast mountains and the Fraser deposited all that sand and gravel at it's mouth, just like what it does at sandheads today.  Also as the weight of the glaciers was reduced, the whole area slowly rose out of the sea (post-glacial rebound).

Atthis point it might not be worth fixing - especially as these type of events are becoming more and more common. :/

there were basically 2 effects on sea level at the end of the Pleistocene; 1) changes in the water cycle water was stored on land as glacial ice which caused sea levels to drop. This was then released when the glaciers melted causing the sea levels to rise. 2) the weight of glacial ice pushed the continental plates beneath and  surrounding the ice sheets down into the earths outer crust. When the ice melted it sprang back up higher than previously. From what I recall when I studied archaeology & geography at SFU the immediate change in sea level locally was a drop of about 600 feet due to ice melting and filling the ocean. Then the depressed plates sprang back up higher than currently then settled back to the levels we more or less have today.

At different times during the glacial melt, the Fraser River flowed to ocean via what we know as Port Moody, and at another stage through Cloverdale to Mud Bay leaving behind  the Serpentine & Nicomekl.

Look at the bright side....if that guy's corner home at the end of the road right hand side washes away.... you guys will be able to fish the rip rap again....without threat of bodily harm.

An Evacuation Order has been issued for properties along Chilliwack Lake Road in FVRD Area E due to immediate danger to life and property caused by high flows and bank erosion in the Chilliwack River.

When I drove by 1.5 weeks ago, it looked like a good chunk of the field below Thompson Park was already washed away. It makes it sound like all of the field is being washed away right now.

Yup. I saw that. Most of Ways field has been washed away. The river now runs along the road instead of on the other side. The river must have smashed trough the rip rap protecting the farmers field. Crazy

Drone footage of the Upper Chwk River.
At 9:45 its flying downstream toward Wilson Rd where you can see damage to the dyke and homes.
Beginning at 12:50, it's flying upstream toward what used to be Way's Field. The main channel now runs through the field, and a large wooded section is...gone.

Looking at the footage it appears substantial parts of the river bed has been paved as in it's mostly riffle structure with not a lot of pool, run and rapid structure. Anyone who has been there have any comment? Over time more normal flows tend to return a more normal structure but it looks like some of those classic 'holes' that anglers like to line up along have filled in.

Reminds me of how the upper Squamish river  has moved around over the last 30 years going from side to side of the valley and back again with lotsa braided channels away from the main flow . River will go where it wants to go  during high water events.

I agree with Ralph, the river is very straight, shallow, and dirty. Tailouts seem wider and flatter. The logs jams are massive with great length and heights. Many trails, access points are destroyed. I have been trying to fish the lower river below the crossing bridge. No catches so far, no blood on the beach either.
 I think Peach road and Lickman might be disappointing to most, but I havn't tried there yet. There is a jam ruining the trail at the stump hole below Lickman, needs a good wade to get around it??? At Hopedale; the access trail has a massive jam there now, not sure if accessible or worth it. Crossing bridge; lots of rip rap missing and the rock stairs also gone.

WOW!   Moving water is powerful.

But what amazes me even more is that, before the rain fell, all that water was supported up in the air for many thousands of miles.

Big long solid rock canyon = hydro-logically a young river structure with high velocity at the canyon terminus   + it's historically has much wider flow swings on a regular basis than the Chilliwack.

just shows that in the U.S. they are moving ahead with doing something about it to mitigate future events.

As the article states studies have been done here but nothing has come of it yet year after year. My frustration sits with the fact that the dyke in abbotsford failed and followed by a 100 meter breach.  If no breach had occured how much less of a disaster would it have been? Whos responsible for the breach in the dyke?
Title: Re: The Great Flood 2021
Post by: DanTfisherman on January 27, 2022, 11:50:32 PM
This is tricky.
From what I understand, the breach took place at the first, lowest spot on the dyke the flooding waters came to where the water could initially trickle over.  As that trickle increased, the volume and velocity of that water increased, increasing erosion at that spot rapidly, until all the water previously held back ripped through that one opening and expanded it to become that 100 meter gash.

So yes, people will look to learn and will build a higher dyke.  But as time goes on and the miles of dyke age and wear, and people forget the past, there will always be one spot a bit lower, and thus weaker and succeptable to erosion.  It could be a spot where the soil depresses and sinks over time.  It could be some unknowing or unsuspecting man made damage.  It could be a grassfire at some time down the line.  It could be cattle or other wildlife somehow impacting the dyke, It could be a freak thunderstorm where pounding rain one time causes some minor, barely noticed erosion, it could be consistent foot traffic in one area of the dyke, it could be an earthquake causes some minor structural issues.  We are talking possibly 50 to 100 years of planning and ongoing consistent monitoring.  We as a species have such a short memory that after 40 years of monitoring and nothing happening to the dyke, the next generation will forget the past, question the expenses, and thus fail to see the logic of continuing on-going expensive efforts.  You can see that this is what happened with the last flood committee that was formed after the 1990 flood.
"After the last significant Nooksack flood in 1990, a cross-border group was created to come up with a mitigation plan. It went dormant in 2011 and was only recently resurrected."

The issue then becomes under the new US plan, there will be increased water heading this way.  Who can make accurate predictions on how all these floodwaters coalescing at a intense flood event will act and how high the water will get.  What I do know is that in the future such events, if the US follows through with their plan, that dyke will need to hold back a larger volume of water, and if it does fail and break through an even taller dyke, imagine how much water will instantly rush through and how big that gash will be next time.
