Our mission is to provide , timely, reliable, impartial scientific information to our local, state, tribal, and federal partners so they can efficiently manage the water resources within their jurisdictions. Our data and research also help to protect the citizens of Idaho against floods, droughts, and other natural hydrologic hazards. Our science focuses on four basic areas of data collection and research: Surface water resources including rivers, lakes, and reservoirs Groundwater resources, both cold water and geothermal Water quality Water use and availability
The mission of the U.S. Geological Survey Colorado Water Science Center is to be the principal source of timely, high-quality science information on Colorado’s water resources, and to be a leader in providing an understanding of how those resources relate to the people and environment of the state. This will help planners, managers, and others to make the decisions necessary for the wise use of these limited and shared resources.
Scientists within the Geospatial Analyses and Applications Team develop and apply geospatial analytical methods to answer broad-scale questions about source-sink and cause-effect relationships between contaminants and vulnerable communities. Multivariate statistics are used to identify connections between landscape gradients and observational data. These connections are used to develop risk assessments and make predictions across broad, regional scales. Datasets and analytical tools developed by the CTT support multiple projects seeking to understand complex source-sink relationships between observational data and landscape characteristics. Datasets, tools, and methods detailed and stored on this community page...

This dataset contains taxonomic and biovolume data for phytoplankton sampled from Detroit Lake, OR, in August, 2019, and August, 2020. Taxonomy is reported to the lowest possible taxonomic level along with total and percent biovolume. Surface grab samples for phytoplankton enumeration were collected with a van Dorn type sampler and then transferred into a clearn polycarbonate churn. Whole water samples were dispensed for total nutrients and phytoplankton identification and enumeration, the latter preserved with 1 percent Lugol's iodine solution. Samples were analyzed at BSA Environmental Services in Beachwood, Ohio. Cell numbers of all identified phytoplankton taxa were quantified on a per milliliter basis using...
