| Description | This study emphasized performance monitoring of the Surface Bypass and Collector (SBC) and two new structures added in 1998: a Simulated Wells Intake (SWI) retrofitted to the powerhouse below the SBC, and a Behavioral Guidance Structure (BGS), attached to the south end of the SBC. The SWI was added to decrease smolt entrainment into turbines and increase their availability to the SBC by flattening flow lines in the forebay. The BGS was designed to divert smolts from Turbines 1-3 toward the SBC or spillway. Different hydroacoustic systems (single-beam, multi-beam, and split-beam technologies) were deployed at many locations to monitor fish passage and fish behavior at the dam. The goal of the fish passage research was to measure the performance of spill, intake screens, and the prototype SBC. The goal of fish behavior studies was to investigate and characterize the behavior of juvenile salmonids as they approached the SBC and the BGS. |
