Biological and Hydrological Impacts of Surface Mining for Federal Minerals on the Tyro Creek Watershed, Alabama. Phase 1. Priming-Aquatic Baseline Information

摘要

This report is a compilation of water quality, hydrological, and biological information collected for four sites in the Tyro Creek watershed (Tuscaloosa County, Alabama) prior to surface mining for federal coal in the Little Tyro Creek lease tract. Samples were collected monthly from September 1981 through September 1982. This information provides a preliminary data base to assess hydrological and aquatic biological effects of surface mining and subsequent reclamation. These effects included high specific conductance, low pH, high sulfate and manganese concentrations, and increased sediment load.
