Page Note: Colorado River at Lees Ferry Streamflow

Current Status: Streamflow is significantly below normal, running at 7,870 ft³/s—33% below the 5-year median and continuing a concerning downward trend.

Key Indicators:

Week-over-week: Down 7.6% (650 ft³/s decline from 8,520)
Month-over-month: Down 7.5% (640 ft³/s decline from 8,510)
Year-over-year: Down 32.2% (3,730 ft³/s decline from 11,600)
vs. Historical baseline: 33.3% below 5-year median

Interpretation: The Colorado River is experiencing sustained low flow conditions. The year-over-year decline of 32% signals a prolonged dry period affecting the basin. Current flows are approaching critically low levels relative to the 5-year average, which has implications for water allocations under the Colorado River Compact and downstream water availability.

Trend: Negative. Flows have declined consistently across all time horizons, with the steepest decline occurring year-over-year, suggesting either sustained drought conditions or upstream management changes affecting Colorado Compact Point discharge.
