Hydrologic data from Naval Oil Shale Reserves, Parachute Creek basin, northwestern Colorado, 1980-81

Two years (water yr 1980 and 1981) of data collected by the U.S. Geological Survey for the U.S. Department of Energy, Naval Petroleum and Oil Shale Reserves, in the Parachute Creek drainage basin of northwestern Colorado are tabulated. Data were obtained from five surface water gages, two automatic sediment samplers, and two water quality monitors. Climate data include maximum, minimum, and average temperature and relative humidity, average wind speed and wind direction, and total daily solar radiation. Daily total precipitation is reported for three stations, and snow-course data reported for one site. (Author 's abstract)

Hydrologic data from Naval Oil Shale Reserves, Parachute Creek basin, northwestern Colorado, water years 1982-83

Data for water years 1982 and 1983, collected by the U.S. Department of Energy, Naval Petroleum and Oil Shale Reserves in the Parachute Creek drainage basin of western Colorado are summarized. These data are supplemental to data reported by Patt and others (1982) and Galyean and others (1983). Data from five streamflow-gaging stations, automatic sediment samplers, and two water quality monitors are presented. The sediment samplers and monitors are located at two of the streamflow-gaging stations. Climate data including mean, maximum, and minimum air temperature and relative humidity, daily solar radiation, mean wind velocity, and mean wind direction are reported for one site. Daily precipitation data are reported for three sites and snow-source data are reported for one site. (USGS)

Lakes Marion-Moultrie stream system investigation, South Carolina : Part II-Simulation Studies

A stream-reservoir model was developed to simulate the operation of the Lakes Marion-Moultrie, South Carolina, reservoir system. The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model, developed for this part of the study, incorporates an inflow component, a diversion-canal component, and a reservoir system component and is capable of evaluating the performance of the reservoir systemem for a variety of operating rule conditions. All model components were verified using observed reservoir input and output data for a 6-year (1967-72 water years) period. In addition, a long-term 31-year simulation under present rule of operation was performed and the results summarized statistically. The model may be used for simulating other rule curves of operation for planning studies of reservoir system performance. (See also W75-05646) (Woodard-USGS)
