Welcome to the official website of Chilliwack River Action Committee! The Chilliwack River has been the focus of extensive community stewardship projects in the past. However, in the last few years erosion has accelerated at several clay slides and stabilization work is now urgently needed to prevent further erosion, mud flows, mud slides and the resulting water siltation problems. Help us to help the river.

Habitat Restoration Work of the Chilliwack River Action Committee for summer 2007:

1. Off-Channel habitat restoration to provide increased fry rearing and over wintering capacity for coho, steelhead and trout:

  • Wingfield and Ryder Creeks - sediment removal from settling ponds and maintenance work, riffle construction.
  • Deer Creek - Rebuild intake and replace blocked culvert leading to spawning and rearing channel.

2. Clay slide stabilization to reduce siltation of the Chilliwack River:

  • plan for sediment monitoring program for the Chilliwack River for the next year.
  • plan for commissioning engineered design and working drawings for stabilizing the top priority clay slides.
  • work toward obtaining the required funding. This is expensive work as it must be planned properly and requires large material and heavy equipment to handle it.

All interested in preserving the health and sustainability of the Chilliwack River Watershed for future generations are urged to support.

Hi Everyone from the Chilliwack River Action Committee,

It has been a very busy summer for the Chilliwack River Action Committee and partner's in habitat restoration.

Projects completed to date with CRAC participation or leadership:

  • Nutrient enhancement of Foley Creek, Centre Creek and Post Creek by placing fertilizer bags under rocks, under direction of Greg Wilson, Steelhead Recovery Program.
  • Off-Channel habitat restoration on Wingfield Creek creating rearing and overwintering ponds increasing the wet area by about 400%, supervisory help by DFO staff.
  • Cleaning the sediment settling pond on Ryder Creek on the and Game Club property
  • Opening blocked culvert on Deer Creek to rewater several km of dry rearing channel and ponds with
  • Thompson Park/Lovely Pond spawning channel, rearing and overwintering ponds, with planning and supervision by DFO staff.
  • Interpretative signage at Thompson Park now being worked on now with DFO staff
  • Trails at Thompson Park are being planed by the FVRD Parks.
  • and the biggest project which we have been working on for over 4 years is the stabilizing of the Tolmie Clay Slide, under direction of CRAC.
  • construction work of groynes should be finished up by mid next week.
  • final work will be seeding and planting trees some time in September. I suggest we have a volunteers day to plant about 50 trees, spread about 50 bales of seed hay, and have an on-site lunch barbeque.
  • Work at Pierce Pond should be done in September, under the planning and supervision of DFO staff.
    Thanks for your help, everyone.

Time: Saturday, October 22, noon to 2:30 pm
Location: Chilliwack Fish and Game Clubhouse

More good news!

This email came in today:

Hello David,

The Southern Fund Committee met last Tuesday, January 11th, to confirm their 2005 spending budget and to make their final selections for projects to be approved for funding.

I am pleased to inform you that your project titled "Chilliwack River Off-Channel Habitat Project" was approved with a budget of $68,900 CAN.

The next step will be to prepare a Contribution Agreement with you and CRAC which I anticipate will happen in February.

Thank you for your interest in the Fund and congratulations on your successful proposal.

Good News!

I just received in today's mail a letter for the Chilliwack River Action Committee from the Pacific Salmon Foundation indicating funding approved in the amount of $8,500.00 for our proposal for 2005 for the "Lovely Pond/ Ryder Creek Restoration and Interpretative Project".

This partnership project with DFO and FVRD Parks in constructing off-channel spawning and rearing channels and creating access for salmon and steelhead smolts, promises to increase habitat highly productive for salmon and steelhead. The proposal also includes constructing interpretative trails from Thompson Park that will add a valuable educational aspect.

A big thank you to the Pacific Salmon Foundation for their continued support of our projects for the health and sustainability of the Chilliwack River watershed.

Congratulations everyone on a job well done. Thank you volunteers, and prize and merchandise donors. The Chilliwack River again is the big winner. More...

Stabilizing the Tolmie Clay Slide 2000 - 2004
Executive Summary

Past logging, road building and development have contributed to the Tolmie Clay slide as an actively eroding area of over 400 meters in length with up to 20,000 cubic meters per year of glacial clay being deposited into the Chilliwack River, degrading downstream 28 kilometers of habitat for steelhead, salmon and other aquatic life with siltation. In November 1995 a major slump of over 50,000 at this slide area partly blocked the river. The work in the summer of 2004 by the Chilliwack River Action Committee has brought most of this problem area under control.

Siltation degrades habitat by sealing spawning gravel and reducing the percolation of fresh water carrying oxygen that is needed for healthy incubation of fish eggs. It also negatively affects aquatic life that is important in the food chain for rearing of fry and smolts. Other related problems related to this clay slide erosion were the possibility of a major slide that could block the river, hazards for the public and reduced fishing opportunity for sports anglers from "colored" water.

The Chilliwack River Action Committee has been researching, and planning for this work for many years. In 2001 Engineers from Golder and Associates were commissioned in partnership between the Fraser Valley Regional District and the Chilliwack River Action Committee to provide a plan that would be cost effective, fish friendly and satisfy government agency requirements. In 2002 they provided a plan of using groynes built to include LWD that would protect the slide toe from erosion as well as adding biodiversity and resting areas for migrating fish during flood events. These groynes are intended to lift the river flow and move it away from the slide toe to reduce erosion and collect other debris against the bank similar to a natural log jam.

During the low water in the summer of 2003 four trial groynes were built near the upstream end of the slide area. In the November flood event of 2003 these groynes performed well at first but were overtopped in the peak of the flood event and erosion took place behind them.

In the summer of 2004 these four groynes were rebuilt, made larger and higher. Twelve new groynes were added to bring the total to 16 groynes protecting 350 meters of slide area. The groynes were built to reach 1 meter above the highest 40 year flood level. However, seventy meters at the downstream end of the Tolmie Clay slide area remain unprotected which will be our project for next year. We went as far as we possibly could this year with a very tight budget. Handling big rock, large stumps and boulders requires very heavy equipment and is expensive. Our original plan was to stage the entire project construction over three years.

Materials used in 2004:
a.. 900 cubic meters of rip rap
b.. 310 cubic meters of granite tie down boulders
c.. 64 large cedar and fir stumps
d.. cable and epoxy to tie down large woody debris

a.. 350 meters of slide erosion slide area now protected
b.. sixteen groynes completed, (four rebuilt, twelve new)
c.. groynes built 1 meter height above 40 year flood level
d.. groynes that add biodiversity and are fish friendly

Costs for 2004:
a.. Cash $62,800.
b.. in kind contributions $37,055. Benefits to the Chilliwack/Vedder River:
a.. reduction in siltation of 28 km. of downstream Chilliwack/Vedder River
b.. improved spawning habitat for steelhead, Chinook, pink and chum and cutthroat and other fish.
c.. added biodiversity to the river system
d.. improved habitat for other aquatic life , insects, part of food chain needed for healthy growth of fry and smolts
e.. reduced hazard for public from clay slide slumps
f.. reduced hazard to residents of debris flows and floods that could result from a river blockage
g.. improved sport fishing opportunity due to less "colored" days of river.

Our partners were:
Our Chilliwack River Action Committee Help Habitat Derby
The Chilliwack Fish and Game Protective Association
The Fraser Valley Salmon Society
The Chilliwack River Valley Ratepayers Association
Terasen Pipelines Ltd.
Fraser Valley Regional District
BC Gaming Commission, Chilliwack Bingo
Pacific Salmon Foundation
Habitat Conservation Trust Fund
And many volunteer hours of work, donations of materials such as the granite tie down boulders, and discounts on equipment rentals.

For cost saving we will likely wait to produce an engineers final report until after next years work.

The Chilliwack River Action Committee continues to work for a healthy and sustainable Chilliwack River Watershed.
