Blue River Watershed Retrospective Assessment Program

Study Area: Blue River Watershed
Period of Project: January 2000-December 2002
Project Number: CO341
Project Chief: Kirby Wynn
Cooperator: Summit Water Quality Committee

BACKGROUND:

The USGS, in cooperation with the Summit Water Quality Committee, will assess the quantity and quality of the surface- and ground-water resources in the Blue River watershed. The study will provide an understanding of the natural and human factors that affect the quantity and quality of the water and the stream biota.

OBJECTIVES:

Specific objectives of the study are:

1. To characterize existing water-resources and stream-biota data for the Blue River watershed.
2. To analyze historical data and assess the broad-scale geographic and seasonal distribution of current water-quantity and quality and stream-biota conditions in the Blue River watershed.
3. To summarize the current knowledge of the environmental setting and identify, describe, and explain, where possible, the major natural and human factors that affect observed water-quantity and -quality conditions.
4. To develop a water-quantity, water-quality, and stream-biota data base.
5. To design a water-quality and stream-biology sampling scheme to fill data gaps and provide information to address water-quality and water-resource management concerns based on results of the retrospective analysis.
