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).

This dataset includes electrical resistance data from a network of 50 data loggers that was installed throughout the Willow-Whitehorse watershed of SE Oregon in September 2014. Data loggers were downloaded in August 2015 and September 2016. These data loggers were used as “electrical resistance” (ER) sensors, following Chapin et al. 2014. The sensors were Onset HOBO Pendant temperature data loggers that were modified to monitor streamflow intermittency and determine the timing of stream drying.

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.

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 (anoxic) conditions using techniques similar to Penn and others (2000); the oxic conditions served as a control and the anoxic conditions represented typical lake sediment environments. Phosphate as phosphorus and total dissolved phosphorus release rates (milligrams phosphorus per square meter per day) were estimated by dividing the change...

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.

This dataset includes spatial location information from 167 temperature data loggers that were installed throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 30 and August 14, 2015. One hundred twelve data loggers were installed in stream channels (some of which were dry), 50 data loggers were installed outside the stream channel to measure air temperature, and 5 data loggers were installed on ridgetops to measure air temperature across the watershed.

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...

This dataset includes stream temperatures from a network of 112 data loggers that was installed in stream channels throughout the Willow/Rock/Frazer watersheds of northern Nevada between July 31 and August 15, 2015. Ninety-seven data loggers were recovered and downloaded in late July 2016.

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...
