This project involved construction of new channel habitats and support structures for salmonid habitat located at North Vancouver Outdoor School (NVOS) (Sue’s Channel) and the restoration of channel habitats that were impacted by the October 2003 flood of record on the Cheakamus River and the August 5, 2005 CN Rail sodium hydroxide spill (Moody’s Channel), located on Squamish First Nation (SFN) I.R. 11. Design and engineering work were undertaken by Fisheries and Oceans Canada (DFO) and NVOS staff during the winter of 2005 - 2006. Construction work started late in 2005 with right of way clearing to facilitate surveys for construction levels, grades and cuts. Initial excavation for the Sue's Channel complex area started in the spring of 2006. These early excavations were funded by the concurrent Mamquam Reunion project. Approx. 1200 m3 of alluvial gravels extracted on-site at NVOS were utilized in that project. Excavation started in earnest in late spring with the start of the "Moody's Channel" phase of the project. Gravels excavated from the Sue's Channel site were used to reconstruct approx. 205 m of Lower Moody's Channel, creating 2278 m2 of enhanced spawning, rearing and refuge habitats for chum, coho, pink, chinook and steelhead. Works also included the installation of 61 pieces of LWD and over 166 boulders. Works on the new Sue's Channel Complex included a 610mm valve assembly and intake pipe, feeding water from the existing Gorbuscha Channel headpond; and the creation of a 380 m, 2400 m2 spawning, rearing and refuge channel for chum, coho, pink, chinook and steelhead. An additional 467 m2 amphibian habitat area was constructed, providing study areas for North Vancouver Outdoor School’s aquatic study programs, accessed by habitat side trails. Works also included the installation of 175 pieces of LWD and over 80 in-channel boulders. There were very few problems during any phase of this project, though some of the cuts were relatively deep and a significant amount of material was excavated from site to complete the project. Several thousand cubic meters of "excess" alluvial gravels were stored on-site at NVOS for future fisheries related projects. Both projects were completed prior to the 2006 chum and coho runs and were well utilized by spawners. "Gee" trapping within weeks of project completion indicated that an abundance of juvenile salmonids had entered and were utilizing both habitats.

iii Introduction

The North Vancouver Outdoor School has worked with BC Hydro, DFO and the Squamish Indian Band to develop a number of salmon habitat restoration projects on the school property and adjacent lands over the last two decades and this project is directed at the restoration and upgrading of these habitats so that they remain productive over time. These various channels and ponds collectively form a large and important component of the off-channel habitat accessible to salmonids and other fishes of the Cheakamus River and were major factors in conserving pink, chinook and coho salmon populations during the recent 2003 flood and 2005 caustic soda spill in the Cheakamus River. This project involves a continuation of the effort to repair, upgrade and expand constructed salmon habitats that were either damaged by recent events on the Cheakamus River or those that require upgrading to improve how they function as fish habitat and further how they deal with future flood and other catastrophic events in the valley. It is very important that these habitats be maintained and improved where possible. Footprint impacts and limiting factors Loss of habitat: The first limiting factor that these projects address is the loss of side channel and off- channel habitat. The off-channel habitat is critically important for species such as coho, chinook, pink and chum salmon. Riverine channels are important for spawning pink and for spawning and rearing 0+ chinook salmon and steelhead trout juveniles. Former spawning and rearing areas have been lost, primarily due to simplification of the Cheakamus River in Reach 4 due to dyke and bridge construction for protection and access to transmission lines, diversion of flows out of the basin directly into the Squamish River and loss of wood and gravel recruitment due to the effects of Daisy Lake created by dam construction (Northwest Hydraulics, 2000). These footprint impacts; such as altered fluvial processes, caused by reduced downstream flows, and controlled flow releases have resulted in less downstream diversity, such as side channels to the main river. This loss of riverine side channels critically limits spawning and rearing habitat for pink and chinook salmon and steelhead trout. Migrating pink fry provide a major source of food for other species, such as steelhead trout and chinook and coho pre-smolts, prior to their migration to saltwater in the spring. Diversions: The second limiting factor addressed is loss of nutrients due to the effects of the Daisy Lake Reservoir and diversion of nutrients out of the basin through the power tunnel to the Squamish River. These projects will increase the biomass of salmon produced by the lower Cheakamus River and thereby increase the amount of marine derived nutrients that enter the ecosystem each year. Loss of nutrients due to the effects of the Daisy Lake reservoir and diversion tunnel are addressed by increasing the source of marine derived nutrients to the lower Cheakamus River. Side channel habitats can increase salmon returns to the river and have the ability to hold salmon carcasses through winter floods and prevent them being swept out of the watershed. This maximizes the value of the marine derived nutrients to the local ecosystem. Goals and Objectives

These projects take advantage of the river intakes on the NVOS property that feed water downstream into constructed channel habitats. The Eagle Point intake provides flows into the Moody’s Channel complex, where a section of side channel was restored to provide optimum habitat for spawning pink, coho and chum salmon. This area will provide another significant refuge for pink salmon embryos during future flood events and should assist in the conservation of this specific population. The expansion of groundwater fed components in the Upper Paradise system, in Sue’s Channel, provides critical spawning habitat for the benefit of chum salmon. The work of the Cheakamus Water Use Plan’s Fish Technical Advisory Committee identified chum spawning capacity in the Cheakamus River as a specific 1 limiting factor. This project adds significant spawning and rearing potential to an already extremely productive channel system. Additional flows provided by the Gorbuscha Channel intake provide habitats critical to trout, chinook and coho.

Similar constructed channel areas along the Cheakamus River played a critical role in conserving a significant proportion of the 2004 brood juvenile coho salmon during the recent 2005 caustic soda spill. Coho fry survived in high numbers within protected side channel habitats and are now re-colonizing heavily affected main stem habitats.

Study Area

These salmon habitat restoration sites are located adjacent to the Cheakamus River within the area known locally as the Paradise Valley. The project focused on two constructed off channel habitats along the Cheakamus River, Moody’s side channel, and the expansion of the Upper Paradise groundwater channel, with the addition of the “Sue’s Channel” complex. Moody’s side channel was originally constructed for the benefit of coho and chum salmon and originally fed by up-welling groundwater alone. Its upstream section originates in the NVOS “duck pond” and has since been augmented by Cheakamus River water flows through the “Eagle Point” intake. Water from the intake flows through the Eagle Point Connector Channel, into the NVOS Canoe Pond and through the Bighouse Connector Channel into the Moody’s system. Both the Eagle Point Connector and Bighouse Connector were completely rebuilt after the 2003 flood. The lower section of Moody’s side channel flows continue through the Squamish Indian Band IR #11, re-entering the Cheakamus River just upstream of the Cheekye River confluence. Upper Paradise Channel is located on North Vancouver Outdoor School, roughly paralleling the BC Hydro transmission line right of way, just south the “bailey bridge”. Sue’s Channel roughly parallels Upper Paradise Channel and is fed by both upwelling groundwater and a controlled flow from the Gorbuscha Channel intake. The property on which these off-channel habitats are located on are either owned by the North Vancouver Outdoor School, School District 44 (North Vancouver), or the Squamish Indian Band. Maps covering the site are Natural Resources Canada National Topographic System 92G/14 and Geo Data British Columbia Terrain Resource Information Management 92G.085 near UTM coordinates of 5519720m N by 488750m E and 92G/14. 5519500mN: 489250m E.

Methods

Excavation was done with Cat 235, 320, 325 and 330 excavators and Cat 950 and 966 loaders. Materials were moved around site by a variety of standard dump trucks and a D250 Cat truck. LWDs were placed using a Cat 325 excavator and transported with standard dump trucks and a D250 Cat truck. Most LWDs were supplied by NVOS though several logs were supplied by the Vancouver Olympic Organizing Committee (VANOC) through a resource sharing arrangement with British Columbia Conservation Fund (BCCF).

2 Trail construction was assisted with a Bobcat skidsteer and 331 excavator. Squamish River Watershed Society (SRWS) and NVOS partnered with DFO during all phases of the design and development of these restoration works. Results

Gravels excavated from the Sue's Channel site were used to reconstruct approx. 205 m of Lower Moody's Channel, creating 2278 m2 of enhanced spawning, rearing and refuge habitats for chum, coho, pink, chinook and steelhead. Works included the installation of 61 pieces of LWD and over 166 boulders. Works on the new Sue's Channel Complex included a 610mm valve assembly and intake pipe, feeding water from the existing Gorbuscha Channel headpond; and the creation of a 380 m, 2400 m2 spawning, rearing and refuge channel for chum, coho, pink, chinook and steelhead. An amphibian habitat area of 467 m2 was also constructed during the project, providing a trail network and study areas for North Vancouver Outdoor School aquatic studies. Works also included the installation of 175 pieces of LWD and over 80 boulders. Approx. 160 meters of channel side trail was constructed including a 15 meter bridge spanning the channel. The center span was roofed, creating a 12 m2 (16 x 7 ft.) “classroom” over the channel.

Works completed include upgrades to connectivity, LWD replacement and repairs after the flood of October 2003 A new, enhanced, Eagle Point Connector channel and Canoe Pond outfall channel were constructed after the 2003 flood. During construction of the 2002, Cheakamus Off Channel project, excavated gravel was hauled in dump trucks 4.5 kilometers upstream and deposited on an active river bar. During flood flow conditions, this gravel was picked up by the river and deposited downstream. This action helped replace eroded gravels in mainstem river spawning areas. Additional funding was provided in 2005 and 2006 to help mitigate the damage caused by October 2003 flood and the August 2005 CN Rail caustic soda spill. Both events had significant impacts, particularly on steelhead, chinook and pink stocks. Recruitment / Repair Dave’s Pond / Eagle Point For more information contact: BCRP @ www.bchydro.com/bcrp/ Gorbuscha Far Point / Mykiss The Far Point intake and outfall ponds were rebuilt in 2004. This involved replacement of pipe, valves and outfall assemblies. The diking protection was upgraded and headponds enlarged. The Mykiss Channel was constructed to provide critical spawning and rearing habitat, primarily for steelhead, chinook and pinks. The BC Hydro Water Use Planning process for the Cheakamus River identified pink salmon and appropriate spawning habitat as a limiting factor. The Gorbuscha Channel complex and intake assembly was completed as a two phase project in 2003 and 2004. These channels provide valuable spawning areas for pink and chinook salmon significant rearing and refuge habitats for steelhead and coho. This channel, and the education that happens here, is a memorial to Sue Emerson, and her dedication to the Bridge Coastal Restoration Program. Tragically she died doing what enjoyed best, hiking the mountains surrounded by all the beauty.
