Estimation of potential bridge scour at bridges on state routes in South Dakota, 2003-07 Estimation of potential bridge scour at bridges on state routes in South Dakota, 2003-07
Flowing water can erode (scour) soils and cause structural failure of a bridge by exposing or undermining bridge foundations (abutments and piers). A rapid scour-estimation technique, known as the level-1.5 method and developed by the U.S. Geological Survey, was used to evaluate potential scour at bridges in South Dakota in a study conducted in cooperation with the South Dakota...

Data collected to support monitoring of constructed emergent sandbar habitat on the Missouri River downstream from Gavins Point Dam, South Dakota and Nebraska, 2004-06 Data collected to support monitoring of constructed emergent sandbar habitat on the Missouri River downstream from Gavins Point Dam, South Dakota and Nebraska, 2004-06
The U.S. Army Corps of Engineers has constructed emergent sandbar habitat on sections of the Missouri River bordering South Dakota and Nebraska downstream from Gavins Point Dam to create and enhance habitat for threatened and endangered bird species. Two areas near river miles 761.3 and 769.8 were selected for construction of emergent sandbar habitat. Pre- and postconstruction data were...

Peak stages from backwater conditions at streamflow-gaging stations in and near South Dakota through water year 2001 Peak stages from backwater conditions at streamflow-gaging stations in and near South Dakota through water year 2001
Stream stages associated with the annual peak discharge are presented for 182 streamflow-gaging stations in and near South Dakota. The peak stage at a station can occur as the result of the annual maximum discharge, but also as the result of backwater conditions. Backwater, often caused by ice, can produce a peak stage higher than the stage coincident with annual maximum discharge. The U...

Evaluation of recharge to the Skunk Creek Aquifer from a constructed wetland near Lyons, South Dakota Evaluation of recharge to the Skunk Creek Aquifer from a constructed wetland near Lyons, South Dakota
A wetland was constructed in the Skunk Creek flood plain near Lyons in southeast South Dakota to mitigate for wetland areas that were filled during construction of a municipal golf course for the city of Sioux Falls. A water-rights permit was obtained to allow the city to pump water from Skunk Creek into the wetland during times when the wetland would be dry. The amount of water seeping...

Water resources of the Lake Traverse Reservation, South and North Dakota, and Roberts County, South Dakota Water resources of the Lake Traverse Reservation, South and North Dakota, and Roberts County, South Dakota
In 1994, the U.S. Geological Survey, in cooperation with the Sisseton-Wahpeton Sioux Tribe; Roberts County; and the South Dakota Department of Environment and Natural Resources, Geological Survey Program, began a 6-year investigation to describe and quantify the water resources of the area within the 1867 boundary of the Lake Traverse Reservation and adjacent parts of Roberts County...
