WATER QUALITY STATUS REPORT, INDIAN CREEK (CANYON COUNTY), IDAHO 1976-1977
Description:
The Indian Creek drainage (17050114) is located in the Boise River Basin of Southwest Idaho. This study was concerned with the portion of Indian Creek near the Nampa and Caldwell urban areas. Major land uses in the area are associated with urban development and irrigated agriculture. Two major point sources discharge to the stream in the study area. These sources were found to elevate instream temperatures, depress dissolved oxygen concentrations, add heavy organic loadings, provide excessive nutrient loads, discharge toxic levels of ammonia and residual chlorine, and cause bacterial contamination. Nonpoint sources such as individual on-site sewage systems, irrigation return flows, animal feeding operations, and urban storm runoff could also be affecting the pollutant load of Indian Creek by adding increased turbidity, sediment, nutrients, and elevated bacteria levels. Water Quality Status Report No. WQ-42. Prepared by: Donald M. Martin and William H. Clark, May 1979. Idaho Dept of Health and Welfare, Division of Environment. 45 pp plus appendices.
