Selenium concentrations in Yuma Ridgway's Rails occupying managed and unmanaged emergent marshes at the Salton Sea

Yuma Ridgway’s rail (Rallus obsoletus yumanensis, hereafter, rail) are an endangered species for which patches of emergent marsh within the Salton Sea watershed comprise a substantial portion of habitat for the species’ disjointed range in the southwestern United States. These areas of emergent marsh include: 1) marshes managed by federal (particularly the U.S. Fish and Wildlife Service’s Sonny Bono Salton Sea National Wildlife Refuge (SBSSNWR), state (California Department of Fish and Wildlife), and local (Imperial Irrigation District) resource agencies that are sustained by direct deliveries of Colorado River water; and 2) unmanaged marshes sustained by agricultural drainage water. Management of rail habitat in this arid environment is complicated by increasingly limited availability of unimpaired freshwater owing by recent water management decisions associated with the Quantification Settlement Agreement, and risks posed by potentially harmful concentrations of selenium (Se) found in agricultural drainage water that can readily bioaccumulate in aquatic food webs.
To provide timely science for managers, the selenium concentrations in this data release are the basis for summary statistics reported in Ricca et al. 2022. These data comprise selenium concentrations and associated  locations and dates of the following matrices sampled to describe  pathways of selenium exposure to rails occupying managed and unmanaged marshes: 1) unfiltered surface water, midge larvae (Chironomidae), water boatmen (Corixidae), mosquitofish (Gambusia spp.) and crayfish (Astacidae). Selenium samples were collected from 15 fixed sampling points each in managed and unmanaged marshes during late February, April, and June of 2016, which corresponded to rail pre-nesting, nesting, and fledgling reproductive life-stages, respectively. Two areas within the two treatment types (managed vs. unmanaged marsh) were of particular interest to help assess risks associated with changing Sea dynamics and different water management strategies: 1) a large unmanaged marsh (Morton Bay) unintentionally created in approximately 2008 when it became separated from the Salton Sea as water inflows began to drop and a berm formed from accumulated sediment; and 2) a restored marsh (HZ-9A) managed by the SBSSNWR, which is currently supplied with Colorado River water, but may be sustained in the future by a blend of clean (that is, low Se) Colorado River and agricultural drainage water with higher Se from the Alamo River.

Historical simulated snowpack and runoff for the Lake Sherburne, MT watershed and vicinity, water years 1980-2019

This data release contains historical SnowModel (Liston and Elder, 2006) output for the Lake Sherburne, MT watershed and surrounding area. The two quantities simulated for this release were snow water equivalent depth (swed), the liquid water equivalent depth stored as snow in the simulation domain, and runoff (roff), which includes snowmelt at the snow-soil interface and rainfall on pixels without snow cover. The simulation used to produce these outputs was conducted on a 30 m geospatial grid and was forced using meteorology from the National Land Data Assimilation System (NLDAS-2, Mitchell and others, 2004; Xia and others, 2012). This simulation used daily snow water equivalent time series from two National Resources Conservation Service snowpack telemetry sites (SNOTEL), Many Glacier and Flattop Mountain, to condition the SnowModel simulation to the observed snowpack (Liston and Heimstra, 2008). Land cover information for the simulation was provided by the 2016 National Land Cover Database (Jin and others, 2019) and 30 m elevation information was provided by the National Elevation Dataset (Gesch and others, 2018).

Debris-flow Video Files for Bridge Cameras (Upper Station), Chalk Cliffs, Colorado, USA, 2019

Chalk Cliffs, located 8 miles southwest of Buena Vista, CO, is one of the most active debris-flow areas in the state (U.S. Geological Survey). This "Child item" page includes videos of floods captured by two of the high-definition cameras at Chalk Cliffs which are located at the Upper Station. This station drains an area of 0.06 km^2 and was used to monitor flow properties and triggering conditions in the headwaters of the study area. It was equipped with two rain gauges, a laser distance meter to measure flow stage, two geophones to record ground vibrations, a force plate to measure the basal impact forces of the flow, and two downward looking video cameras to record flow characteristics (Kean et al., 2020).The two cameras at the Upper station are mounted in stereo approximately 92 cm apart and view the flow immediately upstream of the cross section where flow stage, basal force, and one set of ground vibrations are measured. The observations from these cameras aid in the interpretation of time series data at the cross section and help constrain flow velocity, sediment concentration, and particle grain size. The setup of the two cameras at the Upper Station can be seen in the attached image "Upper_station_setup.JPG". Also see figure “station_and_camera_locations.png” for the location of the cameras and stations at Chalk Cliffs. 
Camera video recording is triggered when the rainfall intensity exceeds a threshold (see Michel et al., 2019). Video files for the camera were downloaded manually during site visits. More detailed information about the camera and settings used can be found in the metadata file under “Process steps” in “Data quality information.”

Debris-flow Video Files for Firehose Camera, Chalk Cliffs, Colorado, USA, 2019

Chalk Cliffs, located 8 miles southwest of Buena Vista, CO, is one of the most active debris-flow areas in the state (U.S. Geological Survey). This "Child item" page includes videos of debris flows captured by one of the high-definition cameras at Chalk Cliffs. This camera was placed at the Firehose Station which is located on the perimeter of the study area at the base of the cliffs and was used to monitor the impacts of cascading water runoff during rainstorms on loose sediment at the cliff base. It was also used to constrain the sediment concentration of flows impacting sediment at the base of the cliff.  It was equipped with a rain gage and video camera to record flow characteristics. See figure “station_and_camera_locations.png” for the location of the cameras and stations at Chalk Cliffs. 
Camera video recording is triggered when the rainfall intensity exceeds a threshold (see Michel et al., 2019). Video files for the camera were downloaded manually during site visits.
