| Abstract: | The general goal of the restoration effort for the Truckee River fish passage project is to re-establish sufficient connectivity to sustain or recover viable populations of native fish species while accommodating social needs and uses of the resource. The ERDC-EL team was tasked with identifying and assessing both upstream and downstream passage alternatives for all native fishes thought to be impacted by fragmentation. The establishment of criteria and goals to address recovery needs for warmwater fishes is an enterprise fraught with knowledge gaps and assumptions. Information is particularly lacking for many of the native species of the Truckee River. Therefore, the project objective was refined to implementation of the most effective measures for fish passage improvement on the Truckee River. Though over 30 structures impede fish passage on the Truckee River, various agencies and owners are addressing many of them. In view of this ongoing work, SPK worked with EL to develop fish passage alternatives at 17 structures on the Truckee River. These structures range significantly in construction, purpose, size, and impact to upstream and downstream fish passage (Table 1; Conyngham et al. 2007). In light of these considerations, ERDC-EL examined each structure, assessed types and degrees of impact, and identified actions to improve fish passage. Site visits, meetings with dam owners and other counterparts, physical site constraints and opportunities, and upstream and downstream passage needs of relevant species all helped determine the selection of two to four alternatives per site. |
