News release: Biden-Harris Administration announces $8.5 million from bipartisan infrastructure law for Colorado River endangered species recovery
Lower water levels at Lake Powell and rising temperatures in the Colorado River are contributing to dangerously low dissolved oxygen levels below Glen Canyon Dam, causing concern for the health of the trout fishery located near Lees Ferry. The Bureau of Reclamation works with the U.S. Geological Survey to closely monitor water quality conditions and is working with partners and stakeholders to better understand potential effects. Fish native to the Colorado River, such as humpback chub and razorback sucker, are generally located farther downstream where low dissolved oxygen levels are remedied by riffles and runs, which aerate the water.
