  • January 22, 2018 - USGS Water Data availability during lapse in Federal funding

    Due to a lapse in Federal funding, the U.S. Geological Survey must suspend those parts of its data collection and distribution processes requiring human intervention. However, automated reporting and serving of telemetered data will continue.

    Users may note some degradation in the quality and completeness of real-time streamflow, groundwater and water-quality data from some reporting stations due to the suspension of field calibrations and adjustments, especially as high flows occur, aquatic vegetation becomes dominant, or ice forms in high altitude streams. The USGS will continue to monitor some performance aspects of its network using a skeleton workforce.
