Colorado River Lake Levels, Water Temperatures
November 2026
The Colorado River is the lifeblood of the desert Southwest. DesertUSA tracks Lake Powell, Lake Mead, Lake Mohave and Lake Havasu with current lake levels, water temperatures, recreation conditions and major river news.
Updated monthly: Follow reservoir levels, Colorado River agreements, Upper Basin snowpack and the spring runoff outlook. The next full update is planned for December 2026.

COLORADO RIVER — WHAT’S HAPPENING NOW
NOVEMBER 2026 Update
- Lake Powell: NOVEMBER ELEVATION 3532 — 25.5% full
- Lake Mead: NOVEMBER ELEVATION 1037 feet —26% full
- 2027 operations: New Colorado River operating rules put increased emphasis on protecting critical elevations at Lake Powell and Lake Mead.
- Water use: Lower Basin reductions and conservation will be a major story as the river enters 2027.
- Winter watch: Attention now turns to the 2026–27 Upper Colorado River Basin snowpack and the amount of spring runoff it can produce.
Will El Niño Help the Colorado River?
A strong El Niño can increase the chances of a wet winter in California and parts of the Southwest, but it does not guarantee a large Colorado River runoff year. Most of the water that eventually reaches Lake Powell begins as mountain snow in the Upper Colorado River Basin, especially in Colorado, Wyoming and Utah.
For the Colorado River, the numbers to watch this winter are Upper Basin snow-water equivalent, spring runoff forecasts and projected inflow into Lake Powell. A wet Southern California winter can occur without producing an equally strong snow year in the river’s headwaters.
DesertUSA Winter 2026–27 River Watch
El Niño: Strong forecast
Upper Basin snowpack: Too early — watch begins as winter storms develop
Lake Powell spring inflow: To be determined
Lake Mead outlook: Dependent on Lake Powell releases, conservation and Lower Basin use
Lake Powell — NOVEMBER 2026
Current elevation: 3532 feet | Capacity: 25%] | One-year change: -13 feet
Lake Powell Rises Nearly 14 Feet in October Following Heavy Rainfall
Lake Powell has experienced an unexpected recovery during October 2026, rising nearly 14 feet following heavy rainfall and flooding across portions of the Upper Colorado River Basin. By October 31, the reservoir had climbed to approximately 3,532 feet above sea level, gaining nearly 800,000 acre-feet of water since the beginning of the 2027 water year on October 1.
The increase provides welcome relief following an extremely poor 2026 snowmelt runoff season. However, Lake Powell remains at only about 25.5% of capacity and is still approximately 13.5 feet below its level at this time last year.
The outlook for 2027 will depend largely on winter snowfall in the Rocky Mountains and the amount of spring runoff reaching the Colorado River. Federal water managers must continue balancing releases to Lake Mead with the need to protect Lake Powell’s storage and maintain reliable operations at Glen Canyon Dam.
Although October’s dramatic rise is encouraging, sustained recovery will require several seasons of improved precipitation and runoff.

Lake Mead — NOVEMBER 2026
Current elevation: 1039 feet | Capacity: 26.4 %] | One-year change: -18.73 feet
Lake Mead remains under pressure from low Colorado River runoff and the need to balance water between the system’s two largest reservoirs. Short-term monsoon flooding can create dramatic river flows, but the volumes are generally small compared with Lake Mead’s enormous storage capacity.
The 2027 outlook will depend on Upper Basin snowpack and runoff, releases from Lake Powell, Lower Basin conservation and implementation of the new operating rules.

2027 Colorado River Water Rules
Colorado River management is entering a new period in 2027. Federal operating decisions for Lake Powell and Lake Mead place greater emphasis on protecting critical reservoir elevations while adjusting water deliveries and conservation to actual hydrologic conditions.
The central problem remains unchanged: water use must increasingly be balanced against the amount of water the river actually produces. Conservation, agricultural efficiency, reservoir operations and agreements among the Basin states, Tribal Nations, Mexico and the federal government will continue to shape the river’s future.
2026–27 Snowpack & Spring Runoff Tracker
Updated November 1, 2026
Upper Basin snowpack: 89% of the seasonal median as of October 31. Snow accumulation is still in its early stages.
Upper Basin precipitation: 190% of average since October 1, reflecting unusually heavy October rainfall.
Lake Powell inflow forecast: 81% of average for water year 2027, according to the latest federal forecast.
Spring runoff outlook: Uncertain. October’s heavy precipitation has substantially increased reservoir inflows, but winter snow accumulation will determine spring runoff.
Lake Powell water level: 3,531.90 feet, up 13.82 feet since October 1.
Next major milestone: Monitor winter snowpack accumulation across Colorado, Utah, and Wyoming. Upper Basin snowpack normally peaks in early April, providing a clearer indication of spring runoff into Lake Powell.
