Thanks for posting, @Oak. Peculiar that Blue Mesa res is @ 29% while Morrow Point is @ 93%.The latest forecast is for Lake Powell to receive 64% of its average April to July inflow. That's a little better than what happened in 2021:
"The inflow to Lake Powell was 28% of normal in 2021. April-July streamflow volumes were closer to normal east of the Continental Divide where snowfall was near to slightly above normal. The 2021 water year produced an inefficient runoff for all river basins in the Intermountain West similarly to the 2020 water year. Streamflow volume forecasts were very low on April 1st at <60% of normal runoff for most of the region. Warm temperatures, dry soils and below average spring precipitation led to a very fast snowmelt in Utah and western Colorado.
"By June 1st seasonal streamflow volume forecasts predicted <50% of normal runoff for nearly the entire Upper Colorado and Great Basins. One cause of inefficient runoff during 2021, was extremely low soil moisture to begin the water year. October 1st 2020 soil moisture values were very low in Utah, western Colorado and parts of western Wyoming. Soils in large areas of Utah and western Colorado were at the lowest moisture levels observed (since 1948) to start a water year. Very low October 1st soil moisture meant that melting snow in spring needed to first recharge soil moisture reservoirs before snowmelt could reach regional rivers."

Morrow Point begins @ the bottom of Blue Mesa dam, and a third reservoir, Crystal, begins @ the base of Morrow Point dam. Blue Mesa dam and reservoir:

Morrow Point dam, in the Black Canyon of the Gunnison river

Crystal dam, farther down the Black Canyon
