The River Forecast Centre is calling for the potential of very high flows in the Lower Fraser over the weekend. Due to forecasted heavy rains in the Fraser headwaters, they are forecasting river flows of up to 13,000-14000 cms at Hope (which equals the 100 year return period) and equates to approx 7.0m + at Mission which is nearing or exceeding the river levels from 1972.

I hope the slide site will be okay. It did not look like that had some of their equipment to high up above the water level.

The Fraser River has been dropping and still is at the South Fort George station so it will be dropping here for at least 3 days. Weather is cool up there, 12 to 14 C and actually they called for snow at the higher levels last night. If the heavy rain does come it will not be here until next week. I think the worst is over for the Lower Fraser Valley.

AS you can see the river is presently dropping so will here for the next 3 days down here.

Unless the rains around Kamloops make a big contribution. I heard that the South Thompson is backing up into the North Thompson causing flooding further northeast. At some point all that water will hit Hope.

The River Forecast Centre’s CLEVER model forecast has been downgraded to a forecast of approximately 6 m at Mission by Monday. The biggest variable is how much rain will fall and where.
Certainly, and thankfully, a big downgrade from yesterday’s forecast.

I think the Thompson River system contributes one third of the water to the Fraser.

Been dropping for 4 days now. I doubt it'll get to 6.
-
Mission gauge still shows a drop, 5.400 on the low tide, 5.548 on the high. The water from upriver will arrive later today or early Sunday morning.Will it reach 6.0?
-
It sure came close. The peak this morning was 5.86 m at Mission.
The river is forecast to remain above 5 m at Mission for the next 10 days.
There is still a lot of water, in all its forms, upcountry!
-
I think overall its good news for fish. Over the last few years reading the sockeye updates I found it disheartening that nearly each update water temp was above average and river flow was below normal. Finally cooler temps and higher flow.
-
This high water will be very hard on Early Stuart sockeye that are trying to migrate right now.

IT does not matter there is almost no early stuart sockeye this year, I guess the few that come this year wont make it past hells gate...Looking at the Discharge at hope its basically been impassible for the last 3 weeks
Since June 1 its been basically above 8000 cms with about a one week period where it dropped to 7000 cms, Explains why there been basically no fish at the big bar slide side. Back in the day when early stuart were harvested this would of been already all over the news. Guess when things are not on peoples plate no one cares. Also to put things in perspective by July 17th last year there we already radio tagging fish and a few days after that they were moving fish by helicopter. Many of the fish at that point to were allready colored up and exhausted. This year is another Disaster for early run fish.

Fraser River discharge at Hope
Critical Levels for Fish Passage through Fraser Canyon:
7000 cms - Early signs of physiological stress evident
8000 cms - Difficultly in migration delaying migration time.
9000 cms - Barrier to migration through Hell's Gate.
-
does anyone know if the lower water temps as well as increased flow result in salmon delaying their migration into the fraser and holding at the mouth?
-
Late run sockeye tend to hold off the Fraser but other stocks have a more defined migration timing. High water also adds extra stress hormones which can cause prespawning mortality. Bad year to be an early returning Fraser salmon

What happened in the 70s and 80s when we had large snowpacks almost every year? Also does the Fraser get too high for the hells gate fish ladder to work? I can remember many years where the Fraser was above 9000cms for weeks at a time during freshet.

we didn't have devastating tree loss from forestry and now even worse the fires. Nothing to hold anything back.

I wonder if the springs, or what's left of them, would school around in front of the park in Hope B.C.
Seems to me to be the most likely spot for them to wait for the velocity to lower.

This data is from last year but it shows what the historical mean is. https://www.pac.dfo-mpo.gc.ca/science/habitat/frw-rfo/reports-rapports/2019/2019-06-28/index-eng.html
this year is far from a normal mean. To be in the 10k cms july 7th and over 9k on july 10 is really abnormal.
This year is above the 1/20 year range, meaning If you are 100 years old you would of seen this happen 5 times in your life (At this exact time of year). The 9k rage is more common in June.
