Homepage for USGS national surface-water data with more than 850,000 station years of time-series data for stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall plus real-time data and tutorial.
Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
Detailed information on Total Maximum Daily Load, the total quantity of a pollutant that a stream can carry and still conform to water quality standards, used as a measurement in the monitoring, assessment, and remediation of polluted waters.
Water quality is important here because this reservoir is the primary supply for Wichita, Kansas. Due to low streamflow during the monitoring period, we expect suspended sediment and phosphorus to be more variable in the future.
Outlines tactical problems that make it difficult for beach managers to use scientific information to make beach closure and advisory decisions. Explains methodologies we are using to address those problems and better prepare local decision makers.
