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 of monitoring, the general location of sampling corresponds to the deep site referenced in Rus and others (2018).

The dataset contains estimates for total phosphorus flux from wastewater treatment plants that discharge to surface water within the Red River of the North Basin in the United States and subbasins. Shapefiles defining the subbasins are available as part of the same data release in which these data are published. Estimates of wastewater treatment plant total phosphorus flux (or load) were calculated by Tammy Ivanhnenko for the years 1978, 1980, 1982, 1984, 1986, 1988, 1990, 1992, 1996, 2000, 2004, 2008, and 2012. Flux estimates were based on the average discharge from the wastewater treatment plants and treatment level, both reported as part of the U.S. Environmental Protection Agency's Clean Watershed Needs Survey,...

For about 10 years, the U.S. Geological Survey (USGS) has monitored water quality and streamflow in three agricultural drainage ditches in an effort to evaluate the influence of best management practices on water quality. These ditches are small tributaries to oxbow lakes located in the Mississippi Alluvial Plain of northwestern Mississippi--two sites (LWSR and LWT2) drain to Lake Washington and one site (BLT1) drains to Bee Lake. Streamflow was intermittent at these sites and the ditches were dry much of the year. When streamflow was present, flows were measured on 15-minute intervals and water-quality samples were collected over the course of the flow event using an automated sampler. These datasets were aggregated...

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 were analyzed for nitrogen and oxygen isotopes associated with nitrate and phosphate, respectively, to identify nutrient sources in Willow Creek Lake.

Five discrete groundwater seepage measurements were collected to make a direct measurement of the flux of water across the sediment-water interface. Change in volume/time is the volumetric rate of flow. The volumetric rate of flow was used to calculate flux velocity (distance/time), by dividing the specific area of the seepage meter (2.70-square-feet). The change in volume over the time the seepage test was conducted is the volumetric flow rate of ground water seepage. Flux velocity could be multiplied by the study area to acquire a shallow groundwater flux.

As a part of the statewide Public Beach Monitoring Program–Bacteria and Microcystin, the Lower Elkhorn Natural Resources District collected weekly samples at Willow Creek Lake to monitor microcystin concentrations. The monitoring generally followed the procedures described by Graham and others (2008) for recreational areas. Sampling occurred weekly during May through September, 2006 to 2014, though data provided in this Data Release are limited to 2012 to 2014. Grab samples were collected from the water surface by wading at the south-shore swimming beach. In the laboratory, the samples underwent three freeze-thaw cycles to lyse the cells prior to analysis using the enzyme-linked immunosorbent assay technique to...

Streamflow was measured at the three largest inflows (the Foster, NT, and ST sites) of Willow Creek Lake and at the outflow of the lake. Flow data were typically available at a 15-minute frequency, but generally were summarized as daily means. Flow data for the Foster, NT, and outflow sites were provided by the Nebraska Department of Natural Resources (NDNR) and were estimated using stage-flow relations applied to measured stage following protocols described by Kennedy (1983). Flow at the ST site was measured by the U.S. Geological Survey using an indirect rating curve with water levels monitored continuously by a submersible pressure transducer and periodic streamflow measurements collected using a Parshall flume...

Flow interaction between Willow Creek Lake and groundwater was calculated from a lake water balance (Healy and others, 2007) in which all of the other flow components were either measured or estimated between 2012 and 2014 (as described in Rus and others, 2018) and the interaction was the residual term. Inflow terms consisted of streamflow at three sites (Foster, NT, and ST) as well as the direct precipitation onto the lake. Measured outflow terms consisted of the streamflow at the outflow site and the direct evaporation from the lake. Increases in lake storage had the same effect on the water balance as an outflow. All components of the water balance were tabulated on a daily basis and converted to units of acre-feet...

In 2014, the USGS Lake Erie Biological Station participated in the Coordinated Science and Monitoring Initiative (CMSI) program, a program founded by the U.S. Environmental Protection Agency (EPA) and Environment Canada in the 1990s as a means to focus collaborative research attention on one of the five Great Lakes each year (on a rotating schedule) as a means to increase scientific knowledge for Great Lakes restoration. The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013). We sampled all trophic levels in all three lake basins across multiple seasons in order to determine nutrient availability...
