Atrazine contamination is most widespread in the Midwest, but extends into Colorado and New Mexico. Environmental and public health groups want water quality protections for the weedkiller.

Keith Gido researches freshwater fish communities and how environmental changes reshape aquatic ecosystems. He says dams can make it more difficult for native fish to survive drought.

Two years after her death, the world-famous grizzly bear's legacy endures. At the same time, federal protections for the species are on their way out the door.

The iconic insects arrive in Utah every summer, but since the 1990s, their populations have declined by 80%. The Trump administration delayed a final decision on protecting them.

New satellite observations show that some global river models struggle to account for dams, reservoirs, and other human influences, raising questions about their reliability for water planning.

Conservation groups collaborate with Hyde Park and Cache Valley to promote water saving landscape while Utah's climate dries.
