ROCK SPRINGS, Wyo. — Strong spring runoff from heavy mountain snow is filling up reservoirs in the upper reaches of the Colorado River drainage in western Wyoming.
Rangelands in western Wyoming are unusually dry but the Green River is flowing high and fast.
Hydrologist Jim Fahey with the National Oceanic and Atmospheric Administration predicts more healthy runoff in the weeks ahead thanks to lingering mountain snow.
Fahey says Fontenelle Reservoir is 67 percent full and could get top 90 percent full by the end of this summer. Flaming Gorge Reservoir is 86 percent full, up from 75 percent in January.
Fahey says flows in the Green River could boost low water levels in Lake Powell and Lake Mead but not by more than 1 or 2 percent.
