Use of Rainfall-Simulator Data in Precipitation-Runoff Modeling Studies

Description: Purpose and scope: The primary purpose of the study is to determine if data on infiltration and runoff obtained from the U.S. Geological Survey rainfall simulator, are useful in defining parameters used in the PRMS, which is used to predict runoff from larger watersheds. Incidental to this purpose are determination of the spatial variability of the parameters measured over the simulation plots and over the watershed, and sensitivity of these parameters in predicting runoff.

Integrated Status and Effectiveness Monitoring Program - Entiat River Rotary Screw Traps,Snorkel Surveys, and Steelhead Redd Surveys, 2008.

Description: The USFWS Mid-Columbia River Fishery Resource Office (MCRFRO) operated two rotary screw traps on the Entiat River as part of the Integrated Status and Effectiveness Monitoring Program from March through November of 2008. Along with the smolt traps, juvenile emigrants were also captured at remote locations throughout the Entiat watershed and its major tributary, the Mad River. A total of 16,782 wild salmonids were PIT tagged during the study period. Of this, 3,961(23.6%) were wild Oncorhynchus mykiss, 6,987 (41.6%) were wild spring run O. tshawytscha, and 5,591 (33.3%) were identified as wild O. tshawytscha of unknown run. Rotary screw trap efficiencies averaged 40.3% at the upper (Rkm 11.0) trap and 7.8% for the lower (Rkm 2.0) trap. These efficiencies were pooled for emigrant O. tshawytscha and O. mykiss. The MCRFRO conducted effectiveness monitoring snorkel surveys at 24 sites during the winter period and 30 sites during the summer and fall periods of 2008 as part of the Integrated Status and Effectiveness Monitoring Program in the Entiat River. The 2008 steelhead spawning grounds surveys were conducted weekly in the main Entiat River from rkm 1.1 to 44.2. A total of 222 steelhead redds were identified over the period from February 28 to June 16 2008 with April being the peak spawning month. Approximately 80% of the steelhead redds were located downstream of the rkm 26.

Magnitude and Frequency of Floods in Small Drainage Basins in Idaho

Description: Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.

Hydrology of Coal-Resource Areas in the Southern Wasatch Plateau, Central Utah

Description: From purpose and scope: The hydrology of coal-resource areas in the southern Wasatch Plateau in central Utah (fig. 1) was studied by the U.S. Geological Survey in cooperation with the U.S. Bureau of Land Management. The study area contains large coal reserves, and much of the area was unleased for mining in 1980. In general, study objectives were to define the surface- and ground-water hydrology and to predict, where possible, the effects of coal mining on the hydrologic system. Watersheds and aquifers that were the sole source of supply for public use were to be identified. The objectives were designed to provide the hydrologic information needed by the U.S. Bureau of Land Management to make sound decisions concerning the leasing of Federal lands for coal mining.

Implementing the Conservation Security Program

Description: This report discusses the Conservation Security Program (CSP), which is a agricultural conservation program created in the 2002 farm bill (P.L. 107-171, ยง2001). It provides incentives for farmers to pursue conservation and helps pay for conservation practices. Unlike some other NRCS programs, it pays for conservation on land that remains in production and makes eligible a wide range of farm lands (cropland, pastureland, rangeland, grassland, prairie land, tribal lands, and forested lands incidental to an agricultural operation)
