Dye tracing investigations were conducted in Cades Cove and Tuckaleechee Cove, two carbonate fensters in the western Great Smoky Mountains. These investigations were conducted as part of a two-year study examining the karst hydrology in the carbonate fensters. Main objectives of the dye tracing investigations were to determine resurgences for cave systems, delineate recharge areas for major springs, and to compare travel times from sink (dye injection point) to resurgence (monitoring site) for the two coves. Over the two-year study period (2017-2018), four different rounds of dye injections were completed, and each round had four dye injection locations, with the exception of the fourth round in September 2018,...

Fish community richness, density, and biomass for entire communities, Brook Trout, Rainbow Trout, and minnows, including site characteristics, and water chemistry (acid neutralizing capacity, pH, nitrate, sulfate, ammonia, calcium, and total aluminum) collected at least once and as many as 13 times at each of 52 stream sites during the same years that fish were inventoried, Great Smoky Mountains National Park, 1993-2014.

Conclusions: Watershed area and the percentage of a watershed that is covered by forest significantly influence watershed sensitivity to acidic deposition. Based on these landscape pattern indicators, one can identify subregions where acid-sensitive streams are most abundant. Thresholds/Learnings: Synopsis: Hypotheses relating to watershed sensitivity to acidic deposition were tested using a geologic classification scheme and available regional data for the Southern Appalachian Mountains region. Landscape characteristics including lithology, elevation, elevational gradients, landscape position, and forest cover were used in the geologic classification scheme. Acid neutralizing capacity (ANC) was used as the stratifying...
