Nebraska Water Science Center

Data and Tools

Continuous and discrete surface-water, groundwater, and water-quality data are collected to provide long-term hydrologic records critical to investigating hydrology, modeling climate-change, evaluating natural and anthropogenic changes in the hydrologic regime, and providing information on water availability to water managers.

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

Genus-level taxonomic data of the phytoplankton community were collected from Willow Creek Lake near Pierce, Nebraska in 2013–14. Algal cell concentration and biomass data also were recorded.

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

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...

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

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, 20

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

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...

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

A variety of nutrient sources transported by multiple flow paths contribute to the nutrient load entering Willow Creek Lake. In addition to Willow Creek, there are several smaller tributaries that contribute streamflow to the lake. As Spalding and others (1992) noted, groundwater interactions with the lake are likely another important contributor to nutrient loading. Nutrient load was computed...

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
