Mining in the upper Clark Fork Basin has resulted in substantial effects on water quality from large amounts of waste materials enriched with metallic contaminants. The U.S. Geological Survey has collected data since 1985 to document changes in water quality that might have resulted from remediation activities.
Sampling began in 2007 to determine biological and chemical characteristics of Fish Creek, Teton County. Macroinvertebrate and algal data collected from 2007 through 2011 are available from this link.
Stage-discharge relationships (ratings) are primarily developed from a graphical analysis of multiple streamflow measurements. Measurements are generally made on 8-week intervals. The frequency/interval of streamflow measurements may change based on a variety of circumstances including (but not limited to) flow conditions and rating definition.
Check your faucets at home -- do any of them drip? Well, maybe it's just a small drip -- how much water can a little drip waste? True, a single drip won't waste much water, but think about each faucet in your home dripping a little bit all day long. What if every faucet in every home on your block ... in your town ... in your state also dripped?
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Washington. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Want to know what's happening right now? Request real-time information from any USGS streamgage with the USGS WaterNow text service. This service responds to your text message with information about the current stage, streamflow, or other parameters collected at the gage.
The WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and...
The National Water Information System (NWIS) is the USGS water data portal where you can find a wealth of historic and real-time data related to floods. The NWIS website also is where you can query peak streamflow data by station, state (...
