It's currently just under 39% full and still taking in water from what's left of Spring runoff.

Federal forecasters are predicting an increasingly dire summer across the Colorado River basin, with the latest projections showing the waterway on track for record-low flows.

The Colorado Basin River Forecast Center’s May projections for the West’s most important river show just 13 percent of average flows into the river’s biggest headwaters reservoir, Lake Powell, amounting to just 800,000 acre-feet.

Monitoring stations across the region’s mountainous headwaters registered record-low snowpack at many locations, he said.
