Crow Creek Surface-Water Quality Study

Science Center Objects

Project Period: 2009-2011
Cooperators: Crow Creek Environmental Protection Agency, U.S. Environmental Protection Agency
Project Chief: Joyce Williamson

Executive Summary

The U.S. Geological Survey (USGS) is cooperating with the Crow Creek Tribe Environmental Protection Agency and the U.S. Environmental Protection Agency to collect water-quality samples from streams, such as Crow Creek, that drain the Crow Creek Indian Reservation in central South Dakota. Crow Creek is a tributary flowing into Lake Frances Case and the Missouri River.  The Crow Creek Tribe is interested in determining background water-quality information and tracking any changes to water quality that may result from animal feeding operations (AFOs) or confined animal feeding operations (CAFOs) in the watershed. The Crow Creek Tribe's Water Quality Coordinator, with assistance from USGS, will be organizing a sampling strategy consisting of 4 to 6 sites to study the water quality of the area surrounding a proposed AFO as well as the areas of Crow Creek, Elm Creek, and Smith Creek. 


The purpose of this project is to assist and train Tribal staff to determine if an AFO is affecting, or will affect, background surface-water quality on the Crow Creek Indian Reservation.  The goals of the study are to: (1) assist the Tribe in the development of a comprehensive water-quality sampling program for the Crow Creek Indian Reservation, (2) assist the Tribe with training in the collection of water-quality samples, (3) assist the Tribe with training in measurement of streamflow, (4) collect and analyze water samples for a select suite of constituents including pH, dissolved oxygen, temperature, conductivity, fecal coliform, total coliform, nitrates, phosphates, and metals at 4 to 6 locations within the Reservation.
