Habitat Suitability and Availability for Rainbow Trout (Oncorhynchus mykiss) in the Canyon Reservoir Tailrace and Evaluation of Side Scan Sonar for Habitat Mapping in a Semi-Wadable River
… Oncorhynchus Mykiss are typically stocked in tailraces across the southeastern United States to mitigate fish habitat and assemblage alterations caused by large impoundments. Hypolimnetic discharges from Canyon Reservoir have created conditions suitable for a coldwater tailrace fishery and …

Factors Influencing Rainbow Smelt Entrainment Through Oahe Dam, South Dakota
… fish species were collected in the Oahe Dam tailrace (tailrace) from May through October or November with paired 1-m diameter, 1-mm (bar measure) mesh Nitex plankton nets. Additionally, water temperature, light intensity, and hydroacoustic abundance of rainbow smelt in Lake Oahe in close …

Entrainment of Rainbow Smelt Through Oahe Dam, South Dakota
… meter nets to collect rainbow smelt in Oahe Dam tailrace, 2) to determine diet and seasonal trends in smelt entrainment, and 3) to determine meter-net efficiency and formulate entrainment estimates. In 1996, rainbow smelt were collected biweekly with a modified kodiak trawl and paired, 0.5 mm and …

Fish-Habitat Associations in Small Backwaters of the Upper Missouri River, North Dakota
… significantly among backwaters located in the tailrace, middle and lower river segments of the Garrison Reach. Woody debris and water temperatures in backwater sites were positively correlated with distance from Garrison Dam. I collected a total of 20 species of fishes from backwater sites of …

The role of fish physiology, behaviour, and water discharge on the attraction and passage of adult sockeye salmon (Oncorhynchus nerka) at the Seton River dam fishway, British Columbia
… levels that were examined. Fish delayed in the tailrace below the fishway entrance significantly longer under intermediate discharge (19.9 h @ 12.7 m³s‾¹) than either the high discharge (9.3 h @ 15.8 m³s‾¹), or the low discharge (7.0 h @11.0 m³s‾¹;) conditions (P = 0.022, and P = 0.015, …

Analysis and design of a new updraft free-exit-flow low-head hydropower turbine system
… hydropower turbine system is designed to enhance tailrace water quality, to minimize fish mortality in turbine flow passage, to improve turbine mechanical performance, and to reduce costs and time of hydropower development. This study applies the theoretical, experimental, and computational …

Linear Power Discretization and Nonlinear Formulations for Optimizing Hydropower in a Pumped Storage System
… efficiency, pump, turbine, spillway discharge, tailrace elevation-discharge, and storage-elevation relationships. Also, there are binary unit dispatch and either/or constraints accommodating spill and gated release. Both formulations are applied to a simplified scheme of the Smith Mountain Lake …

Behavioral Responses of Rainbow Smelt to Sensory Deterrent Systems
… of entrained rainbow smelt to the Lake Oahe tailrace/Lake Sharpe food web be evaluated prior to installation of strobe lights. Light attenuation appears to fluctuate minimally, indicating that strobe lights should consistently deter rainbow smelt throughout the summer months in Lake Oahe. …

Limonology of Shadehill Reservoir, SD and Food Habit of Analysis of its Walleye Fishery
… each of its two main tributaries, and one in the tailrace below the dam. Water temperatures ranged from a high of 21.4 °C in July 1994 to 1. 7 °c in February, 1995 and no summer thermal stratification was observed. Dissolved oxygen (DO) remained high and fell below 4 ppm only once during the study …

Abundance, Standing Stock Biomass and species Composition of Zooplankton in Lake Sakakawea, ND and Uptake of Dissolved Organic Carbon (DOC) by Daphnia pulex
… suggests that variation in total biomass in the tailrace is explained mainly by quantity and diel vulnerability to entrainment of large bodied branchiopods. Export of total zooplankton biomass from Lake Sakakawea was greatest in the spring and early summer (1000-4000 kg DW/day). Export rates …
