Peak-Flow Frequency Analysis for Selected Montana Streamgages

The Montana Department of Resources and Conservation requires peak-flow information for Federal Emergency Management Agency (FEMA) floodplain mapping for various locations across Montana. Accordingly, the USGS WY-MT Water Science Center has published peak-flow frequencies for selected streamgages in the Beaverhead River, Clark Fork, Ruby, Jefferson and Madison River Basins, and for selected...

Streamflow Information Program

The U.S. Geological Survey (USGS) operates and maintains a national network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and effective...

Flaxville Aquifer

The Flaxville aquifer is present in the northern and central parts of the Fort Peck Indian Reservation and consists of sand and gravel that forms extensive plateaus and topographic benches used for dryland farming.  Because many residents rely on groundwater as their primary water supply on the Reservation, the Flaxville and underlying aquifers are important sources of groundwater.  The goal...

Rain and Precipitation

Rain and snow are key elements in the Earth's water cycle, which is vital to all life on Earth. Rainfall is the main way that the water in the skies comes down to Earth, where it fills our lakes and rivers, recharges the underground aquifers, and provides drinks to plants and animals.

Water Meniscus

A meniscus is a curve in the surface of a molecular substance (water, of course) when it touches another material. With water, you can think of it as when water sticks to the inside of a glass.

Fish locomotion and biomechanics as limiting and optimizing factors in fish passage

Swimming ability determines how well fish are able to access habitat, and is a fundamental design consideration for passing fish at dams, road crossings, etc.  The purpose of this study plan is to improve understanding of how fish are able to negotiate zones of high velocity and turbulent flow, such as are found in fishways, culverts, as well as in natural areas.   Swimming performance is...
