Intro

This market tracks whether Lake Mead's water elevation at Hoover Dam will exceed 1045 feet by the end of June 2026. On Kalshi, the leading outcome—that the reservoir will be above this threshold—stands at 94.0%. Resolution will be determined by the official end-of-month water elevation reading from the U.S. Bureau of Reclamation. Watch the June 2026 monthly elevation report, due around July 3, 2026, to see whether Lake Mead maintains levels above the 1045-foot mark amid ongoing drought and water management pressures in the Colorado River Basin.

Kalshi

Resolution is determined by Lake Mead's end-of-month water elevation at Hoover Dam for June 2026, measured in feet. Each market resolves to Yes if the elevation is strictly greater than the specified threshold. The official measurement will be obtained from the U.S. Bureau of Reclamation's official records.

Frequently asked questions

The market resolves on Jul 3, 2026, shortly after the end of June 2026. Resolution is determined by the official end-of-month water elevation reading for Lake Mead, typically reported by the U.S. Bureau of Reclamation. The outcome hinges on whether that final elevation exceeds or falls below the 1044.5-foot threshold. Factors influencing the result include spring and early-summer snowmelt, Colorado River water allocations, evaporation rates, and downstream demand across the Southwest.

Key catalysts include updated snowpack forecasts from the Rocky Mountains, which drive spring runoff into the Colorado River system. Drought declarations and water-allocation decisions by federal and state agencies can shift trader expectations. Unexpected precipitation or heat waves in the basin will alter evaporation and inflow projections. Upstream dam releases and irrigation demand patterns in May and June directly affect Lake Mead's elevation trajectory. Climate reports, seasonal outlooks, and any emergency water-conservation measures announced by Nevada, Arizona, or California will influence market pricing into the June close.
