Description

Truckee Meadows Water Authority’s Glendale Water Supply Improvement Project was needed primarily to continue the supply of municipal drinking water to the Reno and Sparks Nevada area. The failing rubble diversion structure was inefficient for diverting water flow, fish passage, and boating and recreation activities. TMWA initiated the improvement project to repair the diversions inefficiencies. This was a multidiscipline design and implementation process. TMWA worked very hard to include the community and the agencies involved in the project to help form the design and the subsequent use of the diversion. The diversion needed to function for the TMWA goal for providing dependable water while at the same time allowing for river connectivity, fish passage and intake protection, and boater passage. This discussion will present the results of the evaluation and monitoring that TMWA completed not only to meet permit requirements, but to establish an understanding of the methods of assessment and to record the success of fish passage across the diversion. The diversion is designed as an eleven foot high hydraulic impoundment with a full river width roughened channel to provide fish passage. The roughened streambed slope is 4%. It also provides the primary goal of diverting approximately 60 cfs of water through a system of fine plate vertical fish screens, and allows for boater and recreation access as well. Three phases of fish passage measurement methods were completed. The pilot phase, pre-construction and post-construction results will be presented and the methods used to complete these shown and compared. Results indicate excellent fish passage for the full river width roughened channel structure for approval of the Monitoring and Evaluation requirements and nicely provide a great data set for fish passage through a roughened channel of many of the Truckee River native fish species. This may be the first rigorous evaluation and measurement of fish passage across a large full river width roughened channel fish pass. The results show the usefulness of this type of fish passage and the effectiveness for its application at other locations. As the costs to complete these types of solutions become lower as compared to other methods of fish passage, we now have a clear measured understanding of their excellent performance to go into the future.

He focuses all of his work on the aspects of fisheries engineering and has been involved in the design and construction of many fish passage, fish screens, fishery management, and fish facilities throughout his 30 year career. Mr. Kidder started his career working beside the late Milo C. Bell in the 80’s and 90’s and has never looked back on the business of solving fish passage problems for clients around the West, Alaska, and the Great Basin. Chinook Engineering is celebrating its 24th year anniversary.
