Description

There is increasing attention being given to the safe downstream passage of migratory fish past dams or other instream obstacles. This is due to the potential for increased exposure of these fish to predation, high mortality or injury created by passage through turbines, spillways or outlet works. For downstream migratory species prone to moving near the surface, the use of floating surface collectors has been proven to be effective, though these have typically been very expensive and fixed in one location. This paper will present information on two small scale, relatively inexpensive, floating surface collectors currently under design and scheduled for construction and deployment in the fall of 2012. One will be installed in a reservoir with a modest amount of water level fluctuation and will be located at a fixed horizontal position. This installation will be operated with gravity water flow through the collector. The other collector, to be installed in a reservoir with up to 185 ft of water level fluctuation, is designed to be both transportable between different water bodies as well as movable between different collection locations within a reservoir. This second, more portable design, utilizes off the shelf components and is operated with pumped fish attraction and transport flow. Information to be presented will include design criteria considerations, a description of operations, and the monitoring plans designed to measure the effectiveness of each collector installation.

Comments

Mike McGowan, P.E. received a BS and MS in Civil Engineering from Colorado State University and has worked in private practice for over 32 years. 20 of these years have focused on projects related to different aspects of fisheries including passage, screening and fish production throughout the western states. A Senior Project Manager with HDR Engineering, Inc, he is currently involved with the design of two unique floating surface collectors being designed to facilitate downstream passage of salmonids past two existing dams. He is currently coming off a 4 year assignment in Anchorage Alaska where he was the design project manager and on-site technical representative during construction for a new, 78 million dollar facility, that incorporated intensive recirculation rearing systems within a 3 acre building.
