See how each federal plan plays out for Powell

The April 2026 rescue is a patch. The real question is which long-term plan holds Powell up over the next 5–40 years. Run the simulator, tweak inflows and policies, and watch the outcomes.

What the April 2026 federal plan will do to Lake Powell

In April 2026, the Bureau of Reclamation cut how much water Powell sends downstream and started moving water in from Flaming Gorge. The chart below shows where the lake lands with the plan compared to without it, from today through April 2027.

Through September 30, 2026, releases are cut from 7.48 MAF a year down to 6.0 MAF. Up to 1 MAF of water gets moved from Flaming Gorge into Powell between now and April 2027. The plan commits to keeping Powell at or above 3,500 ft — the “safety line” 10 ft above the point where the dam can’t make power anymore.

How much water flows in and out each day — including this year’s snowmelt (give or take 20%) and evaporation.

With the plan, Powell drops to 3513 ft by April 2027. Without it, the lake would drop to 3412 ft — that’s 116 ft down. The plan saves 101 ft. That’s 13 ft above the plan’s 3500 ft safety line.

See the math

Over the next 12 months

  • In: ≈4.0 MAF (0.28 MAF snowmelt + 1 MAF from Flaming Gorge + base flow)
  • Out: ≈4.0 MAF released to the Lower Basin — 1.6× what the plan adds
  • Evaporation: ≈0.43 MAF off the surface

Net: -0.41 MAF. At 3528 ft, each foot of canyon holds about 61K acre-feet → that means a -15-ft drop to 3513 ft by April 2027.

The plan saves 101 ft. Without it, Powell drops to 3412 ft (-116 ft). Not a rise — a rescue.

This is just the patch through April 2027. Run the long-term simulator → to see which plan actually holds Powell up past 2026.

With the plan — smaller releases + Flaming Gorge water
Without the plan — normal releases, no Flaming Gorge transfer
2022 actuals — last Flaming Gorge emergency release (~500 KAF)

The gap between the two lines is what the plan buys.

Context — the 2022 release: Powell went from 3530 ft to 3525 ft over the last Flaming Gorge emergency release window — a net -5 ft.

The 2022 release (~500 KAF under the DROA) ran May 2022 → April 2023. Emergency releases from Flaming Gorge slow Powell's decline; they don't reverse it on their own. The 2022 window had different snowpack and smaller cuts, so this is a historical reference — not a forecast.

How the lake holds water at each elevation

Each band is 15 feet tall. Wider bands hold more water. The canyon is V-shaped, so higher elevations hold a lot more water per foot than lower ones.
