Summary Utah/Western Colo, 1992 System Study, United States Department Of Energy Western Area Power Administration
All U.S. Government Documents (Utah Regional Depository)
The Utah/western Colorado area of the Rocky Mountain Region has adequate coal and water resources to support additional thermal generation plants beyond those already in service. Also within the region are several sites suitable for large-sized hydroelectric pumped-storage projects for purposes of supplying peaking power. The close proximity of these types of electric generating facilities is desirable in providing offpeak energy during the pumping cycle for the pumped-storage units. Considering that the potential capacity of each type of generation is in the 500 to 1,000 (two units) MW range per site and would require major extra-high-voltage (EHV) transmission developments, it …

A User's Manual For Computer Programs Used In: Model Choice: An Operational Comparison Of Stochastic Streamflow Models For Droughts, W. Robert James, David S. Bowles, Nath T. Kottegoda
Reports
The rapid development of stochastic or operational hydrology over the past 10 years has led to the need for some comparative analyses of the currently available long-term persistence models. Five annual stochastic streamflow generation models (autoregressive, autoregressive-moviing-average (ARMA), ARMA-Markov, fast fractional Gaussian noise, and broken line) are compared on their ability to preserved drought-related time series properties and annual statistics. Using Monto Carlo generation procedures and comparing the average generated statistics and drought or water supply properties, a basis is established to evaluated model performance on four different Utah study streams. A seasonal disaggregation model is applied to each of …

Update On Estimation Of Water Surface Elevation Probabilities For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield
Reports
The techniques of operational hydrology, employing an autoregrssive moving average (ARMA (1,0) model were used to replicate historical patterns of streamflow into, precipitation on, and evaporation from the Great Salt Lake. The results were combined with a lake water balance model to simulate lake stage sequences beginning with known initial conditions and extending up to 125 years into the future and used to generate probability distributions for future lake stages. Starting with a spring 1980 high stage of 4200.45 ft msl, the best estimate is that the 1981 spring high will be 4200.19, but there is one change in four …
Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen
Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen
Reports
The Sevier River Basin is a water short basin wherein upstream diversions not consumptively used become the water right for downstream users. The diversion-return cycle occurs several times as the stream travels from its mountain source areas to the terminal lake at the lower end of the basin. This study dealt with the proposed implementation of conservation measures which would wawste less diverted water and allow for irrigation of additional acres. The objective was to predict the hydrosalinity impacts of the implementation of these measures. The results indicated that increased consumptive use in the upper areas would decrease the water …

Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley
Initial Growth And Survival Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Ponds, James J. Shelley
Electronic Theses and Dissertations
Initial growth and survival rates were estimated for bluegills (Leponis macrochirus) and black bullheads (Ictalurus melas) stocked simultaneously with largemouth bass (Micropterus salmoides) in ponds throughout South Dakota. Mean first year survival for bluegills and black bullheads stocked in eastern South Dakota ponds was 28.6% and 67.7%, respectively. Differences in first year bluegill growth throughout the state were not detected. Total lengths for bluegills averaged 52.4 mm after one growing season statewide and 137.1 mm after two growing seasons in southeastern South Dakota ponds. Significant (P<.05) geographical differences in first year growth of black bullheads were detected with mean lengths ranging from 67.7 mm in northwest ponds to 115.5 mm in southeast ponds. The average total length for black bullheads after two growing season in southeastern South Dakota ponds was 215.2 mm. The combined effects of pH, turbidity, and bicarbonate alkalinity accounted for 67.5% of the variation in first year bluegill growth. The pond parameters total number of growing days, fish present prior to stocking, and pond surface area when combined accounted for 73.9% of the variation in first year black bullhead growth. Differences in bluegill relative weight values were not detected throughout South Dakota; the average for the state was 105.2. Mean black bullhead condition factors (K) for fish with total lengths between 128 and 191 mm were 1.85 and 1.45 for pre- and post-spawning periods, respectively. Bullheads probably spawned between 29 May and 26 June 1980.

The Physical And Chemical Limnology Of Lake Mcconaughy With Reference To Fisheries Management, Melvin W. Taylor, Kit M. Hams
Nebraska Game and Parks Commission: Publications
Lake McConaughy is an important fishery resource of the state of Nebraska. The estimated fishing pressure in 1975 as determined from a postal creel census was 175,872 angler days (Morris 1977). This estimate is inflated compared to an on-site creel census conducted in 1977-78 which showed a total of 69,500 fishing trips annually (Madsen 1980). Not all fishermen were contacted so this estimate is undoubtedly too low. Regardless of which figure is accepted, the reservoir provides many man-days of fishing opportunity. Conservation and management of the fishery resource is necessary to maintain and/or improve its quality,
