SIR 2013-5082 Cover

Abstract: To assist in understanding sediment loadings and the management of water resources, a bathymetric survey was conducted in the part of Lake Linganore between Boyers Mill Road Bridge and Bens Branch in Frederick County, Maryland. Carographic representations of both water depth and sediment accumulation in 2012 were produced and compared with cartographic maps of the valley in 1972 prior to inundation. Measurements of water storage capacity indicate a loss of about 65 percent of the original water storage capacity in the 40 years since dam construction. The total accumulated sediment mass was 156,000 metric tons between 1972 and 2012.

SIR 2006-5179 Cover

Abstract: Stream restoration efforts have been ongoing in Maryland since the early 1990s. The primary goal of many restoration efforts is to re-establish geomorphic stability of the stream channel and reduce erosive energy from urban runoff. Monitoring streams prior to and after restoration could help quantify other possible benefits of stream restoration, such as improved water quality and biota. This report presents general watershed characteristics associated with the Minebank Run watershed; a small, urban watershed in the south-central section of Baltimore County, Maryland. The physiography, geology, hydrology, land use, soils, and pre-restoration geomorphic setting of the unrestored stream channel are discussed.

Open File Report 2010-1310 Cover

Abstract: Maryland's population grew by 35 percent between 1970 and 2000, and is expected to increase by an additional 27 percent between 2000 and 2030. Because domestic water demand generally increases in proportion to population growth, Maryland will be facing increased pressure on water resources over the next 20 years. To provide the Maryland Department of the Environment with tools for making future water-resources decisions, the U.S. Geological Survey initiated a study to compute low-flow statistics for selected streamgage locations in Maryland that have 10 or more years of continuous streamflow records.
