Monitoring Data for Willow Creek Lake, Nebraska, 2012-14

Monitoring data were collected from the Willow Creek drainage basin and Willow Creek Lake with a focus on 2012-14. Included are datasets of meteorology; lake measurements of water levels, sediment nutrients, and physical, chemical, and biological data; streamflow and stream chemistry; and calculated nutrient loads to the lake.

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Lake Level

Daily measurements of Willow Creek Lake water storage were provided by the Nebraska Department of Natural Resources for 2012–14. These water levels were used in conjunction with a table (provided by the Lower Elkhorn Natural Resources District) relating lake storage volume to surface area. From these, daily estimates of surface area were derived for the lake.

Niobrara River suspended-sediment and bed-sediment data collected during hydroelectric dam flush near Spencer, Nebr., October through November, 2014

In the fall of 2014 (October-November) the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers collected sediment samples (suspended and bed material) at several sites on the Niobrara River in Nebraska near the Spencer Dam prior to, during, and immediately after a sediment-flushing event. Suspended-sediment samples were analyzed for sediment concentration and p

Depth grids of the flood-inundation maps for the Salamonie River at Portland, Indiana

Digital flood-inundation maps for a 6.5-mile reach of the Salamonie River at Portland, Indiana, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science website at https://water.usgs.gov/...

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Profiler

The data set contains vertical profiles of physical (water temperature, specific conductance, pH, dissolved oxygen, and turbidity) and biological measurements (chlorophyll-a and phycocyanin) that were measured hourly and then summarized on a daily basis within Willow Creek Lake during the non-winter seasons.

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Sediment Nutrients

The retention or release of nutrients into the water column from sediment, also known as internal loading, is another source of nutrients to the lake water column. Sediment cores collected from Willow Creek Lake in September 2013 and June 2014 were incubated for 7 days to assess potential for sediment to produce or consume water column phosphorus under aerobic (oxic) and anaerobic (ano

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Meteorology

A meteorological station was deployed on the dam to measure hourly relative humidity, wind speed and direction, and photosynthetically active radiation between August 3, 2012 and October 30, 2014, with air temperature and solar radiation added on April 30, 2013. Additional meteorological data were obtained from the National Climatic Data Center (2015): Precipitation data were obtained from...

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Lake Chemistry

Samples were collected from Willow Creek Lake approximately monthly during May through September by the Nebraska Department of Environmental Quality as a part of the Ambient Lake Monitoring Program since at least 1989. Lake samples were analyzed for several constituents, including nutrients and chlorophyll. Though several different station identification numbers have been used over the course...

Monitoring Data for Willow Creek Lake, Nebraska, 2012–14—Sampling Data

Chemistry data were collected or compiled from stream water, lake water, and groundwater. Stream water samples were collected more frequently to capture the range of streamflow conditions. Discretely collected samples were analyzed for nitrogen content (total Kjeldahl nitrogen and nitrate plus nitrite nitrogen) and phosphorus (total phosphorus and phosphate as phosphorus). A subset of samples...
