Mountaintop mining and valley fill (MTM/VF) coal extraction, practiced in the Central Appalachian region, represents a dramatic landscape-scale disturbance. MTM operations remove as much as 300 m of rock, soil, and vegetation from ridge tops to access deep coal seams and much of this material is placed in adjacent headwater streams altering landcover, drainage network, and topography. In spite of its scale, extent, and potential for continued use, the effects MTM/VF on catchment hydrology is poorly understood. Previous reviews focus on water quality and ecosystem health impacts, but little is known about how MTM/VF affects hydrology, particularly the movement and storage of water, hence the hydrologic processes that ultimately control flood generation, water chemistry, and biology. This paper aggregates the existing knowledge about the hydrologic impacts of MTM/VF to identify areas where further scientific investigation is needed. While contemporary surface mining generally increases peak and total runoff, the limited MTM/VF studies reveal significant variability in hydrologic response. Significant knowledge gaps relate to limited understanding of hydrologic processes in these systems. Until the hydrologic impact of this practice is better understood, efforts to reduce water quantity and quality problems and ecosystem degradation will be difficult to achieve.

“…Both the removal of streamside vegetation and increased impervious surface typically result in increased surface runoff and hydrologic variability (Trimble et al, 1987;Potter, 1991). These changes, in turn, lead to increased rates of erosion, increased loads of suspended and deposited fine sediments (Glenn, 1911;Ellis, 1936;Magilligan & Stamp, 1997), and elevated nutrient concentrations (Paul & Meyer, 2001;Groffman et al, 2003).…”

Influence of urban tributaries on freshwater mussel populations in a biologically diverse piedmont (USA) stream

et al. 2009

The Southeastern USA is currently experiencing a period of rapid growth of human populations that is likely having profound effects on the region's unique aquatic biota. Using both survey data and experimental protocols, we assessed the influences of water and habitat quality on freshwater mussel populations in a small Piedmont stream. Chewacla Creek is a high-quality stream located near the rapidly growing towns of Auburn and Opelika in east-central Alabama. From 1999 to 2007 we monitored freshwater mussel populations and measured substrate and water chemistry variables in Chewacla Creek. Surveys revealed that mussel abundance decreased substantially concomitant with degraded habitat and water quality downstream of three highly urbanized tributaries. We conducted sentinel trials using adult mussels (Villosa lienosa) in Chewacla Creek and a tributary (Parkerson Mill Creek) that receives wastewater discharge. Sentinel mussels were placed in cages at three locations downstream of the effluent discharge point and at one upstream site (control). Sentinel mussels exposed to wastewater discharge exhibited lower survival rates compared to control animals. Together, survey and experimental data suggest that degraded tributary subcatchments may fragment mussel populations in highquality streams. Moreover, our data indicate that protection of sensitive aquatic taxa necessitates effective management of water quality across large spatial scales.

“…A study by Potter (1991) attributed increased baseflow in a stream in eastern Wisconsin to advances in farming practices that resulted in increased recharge. A streamflow-trend study by Gebert and Krug (1996) concluded that decreased flood peaks and increased annual low flows in streams from the Wisconsin Driftless Area were caused by changes in agricultural practices and land use.…”

Analysis of streamflow and water-quality data at two long-term monitoring sites on the St. Croix River, Wisconsin and Minnesota

Streamflow of the St. Croix River has been monitored on a long-term basis by the U.S. Geological Survey (USGS) at streamflow-gaging stations on the St. Water-quality sampling conducted by the USGS at two associated water-quality monitoring sites from 1964 to 2001 have included analysis for nutrients, suspended sediments, metals, bacteria, and pesticides. The water-quality data at the two sites had considerable temporal variation and was often limited in extent by the data-collection needs of previous projects. The absence of consistent long-term water-quality data made detection of statistically significant trends in the water-quality data difficult. Nutrient, suspended-sediment, and major ion concentrations and field parameters were generally higher and more variable at the St. Croix Falls site than at the Danbury site. However, disparate sampling periods and strategies could cause possible biases in the comparison of water quality between sites. IntroductionThe U.S. Geological Survey (USGS) has performed long-term continuous streamflow measurements of the St. Croix River at two streamflow-gaging stations: at Wisconsin State Highway 35 near Danbury, Wisconsin and below the dam at St. Croix Falls, Wisconsin ( fig. 1). Water-quality measurements of a variety of constituents such as nutrients, suspended sediments, metals, bacteria, and pesticides have been collected at two water-quality monitoring sites associated with these streamflow-gaging stations. This report will refer to both the streamflow-gaging stations and associated water-quality monitoring sites as sites.This study, which was initiated in 2001, was a cooperative effort between the USGS, National Park Service (NPS), and the Joint Water Quality Commission of Danbury and St. Croix Chippewa Indians of Wisconsin to analyze the long-term USGS flow data for temporal trends and provide summaries and analysis of the USGS water-quality data collected at these sites. This report presents trends in flow and differences in water quality among sites, studies, and over time. Streamflow data from 1902 to 2001 and water-quality data from 1964 to 2001 are included in this study.Differences between the long-term data sets can be used to determine the part of the St. Croix River Basin where change has occurred. Trends at the Danbury site reflect changes in the upper basin (1,580 square miles), trends in the difference between the St. Croix Falls and Danbury sites reflect changes that occurred in the part of the drainage basin between those two sites (4,660 square miles), and trends at the St. Croix Falls Printed on recycled paperAccess data online at http://wi.waterdata.usgs.gov/nwis
