Summary

CPCB facilitated a regional sediment workgroup consisting of aquatic ecologists, biologists, and hydrologists from throughout EPA Region 7 to evaluate linkages between sediment indicators and biological indicators within streams of the Central Plains region. The overall goal of this project was to promote the identification, quantification, and understanding of sediment and sediment erosion processes on aquatic life.

In order to accomplish the project goals, the workgroup will 1) identified and assessed current sediment/aquatic resource information relative to regional needs; 2) conducted an exhaustive literature search to compile existing data on relationships between sediment indicators and associated biological indicators in streams throughout the United States; 3) collected and organized regional data on sediment and biological indicators from organizations and researchers within Region 7, and 4) used multivariate statistical analyses to evaluate relationships between sediment and biological indicators. The results from these analyses will be used to develop a second year proposal designed to test specific hypotheses regarding linkages between sediment and biological indicators within streams of the Central Plains region. Combined, this research will provide the framework for assessing sediment impairment within the Central Plains region and for the development of sediment-related TMDLs.
