Drainage areas in the James River basin in eastern South Dakota

The James River of eastern South Dakota contains an important surface-water supply for the agricultural economy within the basin. Proposed water-resource development has prompted numerous hydrologic studies of the James River. To aid in planning for future development, the map delineates all named stream basins, and all unnamed basins larger than 10 square miles within the James River basin South Dakota and lists by stream name and area of each basin. Stream drainage basins were delineated by visual interpretation of contour information of U.S. Geological Survey seven and one-half minute topographic maps. Two tables list areas of drainage basins, reaches, and noncontributing areas and drainage areas above gaging stations. (USGS)

Analyses of flood-flow frequency for selected gaging stations in South Dakota through September 1985

Analyses of flood-flow frequency were made for 80 active continuous-record gaging stations and 105 discontinued crest-stage partial-record stations in South Dakota with 10 or more years of record. The analyses were developed using the log-Pearson Type III procedure recommended by the U.S. Water Resources Council (Interagency Advisory Committee on Water Data, 1981.) (USGS)
