From Snow to Flow

A majority of the water in the western U.S. comes from snowmelt, but changes in the timing, magnitude, and duration of snowmelt can alter water availability downstream. This data visualization story explores what changing snowmelt means for water in the West, and how new USGS efforts can advance snow science by modeling snowpack and snowmelt dynamics and linking these results to streamflow....

Multisource Water-Quality Trends in the Delaware River Basin

Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin...

Surface Water Flow Trends in the Nation's Streams and Rivers

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.
