Satellite Derived Measures of Cyanobacteria
Cyanobacteria blooms are an environmental and human health problem across the US. They are capable of producing toxins, odors, and surface scum that threaten the health of humans and animals, the quality of drinking water supplies, and the ecosystems in which they develop. EPA developed the CyAN app and CyANWeb, easy-to-use and customizable applications that provide access to algal bloom satellite data for over 2,000 of the largest lakes and reservoirs across the US. States with lakes, like Wyoming, can use CyAN to make faster and better-informed management decisions related to cyanobacterial blooms.
Microbial Sampling at Yellowstone National Park
EPA researchers and Yellowstone National Park collaborated on a 5-month sampling campaign during the 2021 park visitation season. The goal of the effort was to characterize the microbial quality in shallow well and spring collector systems used to supply water for the park's drinking water infrastructure.

Wildfire Impacts on Seasonal Water Temperatures
Over the past thirty years, high-severity wildfires have become more pervasive across the western US. High-severity fires can burn down riparian vegetation that offers shade to streams, stabilize streambanks, and trap sediments and precipitation. Water resource managers in the region are concerned about wildfires’ effect on streams thermal regimes and their implications for salmonids. EPA researchers assessed wildfire effects on the winter and summer water temperature indices of stream stations at Boulder Creek (Oregon), Elk Creek (Oregon), and Gibbon River (Wyoming).
