"The objectives of this 3-year study were to determine (1) budgets of H+, Ca+ +, CI-, NOS-N, NH3-N, and S04= for a 38.9-ha forested watershed and (2) changes in concentration of these constituents that occur in the tree canopy, the soil and bedrock, and the stream channel. Sampling points were two forest openings for bulk precipitation, 20 throughfall sites, four springs where water first seeps out of the soil, and the main stream at the watershed outlet. The most important conclusion was that sulfate is accumulating in the watershed. Average annual kglha of sulfate were: bulk precipitation = 39.9, throughfall = 53.0, and stream = 25.1. Sulfate budgets are compared with published results from five other study sites in the hardwood region of the Eastern United States and with some results from Germany.S3.

The study area, called the High Ridge evaluation area, is located in the Blue Mountains 22 km. northwest of Elgin and consists of four watersheds ranging between 24 and 118 hectares in size. The study's purpose is to identify the pretreatment conditions of hydrologic behavior in determining effects of management practices. Data collected: precipitation; snow depth and density; streamflow; air, soil, and water temperatures; and speed and direction of wind.
