Abstract
This paper will discuss the use of a three-dimensional physical model of John Day Lock and Dam, Columbia River to investigate alternatives to improve fish passage at the structure. A 1:80 scale physical model of the site was constructed to investigate flow conditions developed under various operating procedures. The model reproduces the Columbia River from river mile 212.5 to 219.5. The hydraulic experiments investigate fish passage improvement measures required under the Columbia River Juvenile Fish Mitigation Program for the John Day Project. Experiments are being conducted to investigate spill patterns for juvenile fish, drawdown options, gate spill patterns for adult fish, proper location of a juvenile fish transportation facility, and flow conditions approaching the powerhouse intakes.
