Mid-Columbia Fisheries (MCF) enhanced flow connectivity to a 0.6-mile Yakima River side channel (RM 153.5) that supplies irrigation water to Bull Canal. The project is located in Irene Rinehart Riverfront Park in Ellensburg, Washington and included the following elements: 1) Removing two gated culverts at the head of the side channel and replacing with a bridge to improve conveyance and reduce sediment deposition. Before removal, the gated culverts were not considered fish passage barriers, but they greatly impacted the flow and sediment dynamics of the side channel; the side channel did not experience the scouring flows that could have moved sediment through and maintained a thalweg. The new bridge allows for scour and sediment transport. 2) Regrading the accumulated material immediately up- and downstream of the gated culverts to restore flow conveyance and reduce fish stranding. In 1998, WA Dept. of Fish and Wildlife installed a channel-spanning weir to direct flow into a 0.6 mi. side channel at RM 153.5 of the Yakima River. From April 15 to late August each year, Bull Canal Company (BCC) diverts up to 45 cfs into a pipe located 2,000 feet down the side channel. This project did not make any changes to the channel-spanning weir. Prior to this project, the side channel would immediately dewater in late August when managed flow in the Yakima River was lowered, causing fish to be stranded in the side channel and subject to increased predation. In response to significantly higher than anticipated construction bids, MCF worked with the project steering committee to reduced the project scope and secured approval to remove a) the extensive channel regrading element, b) the roughened channel at the downstream end; and c) the wood structures on the Yakima River bank. Although Beaver Dam Analogs (BDAs) were included in the amended project scope and project permitting, MCF and partners are waiting to see if their installation is warranted. At the time of this report, beaver activity and willow tree falling have combined to impound water in the area where BDAs were scoped, making the installation of BDAs redundant. MCF will monitor the extent and duration of side channel dewatering. If dewatering remains precipitous when the Yakima River is lowered, MCF will work with partners and USFWS funding to install Beaver Dam Analogs or similar features to improve fish survival during dewatering. This project was designed to reduce or prevent stranding mortality due to rapid dewatering of the Yakima River side channel and to allow the side channel to serve as high quality rearing habitat for juvenile spring Chinook, coho, and steelhead. During the fish relocation necessitated by project construction, we learned that the site provides habitat for lamprey as well.
