## National Hydrological Crisis Deepens Across Multiple Regions

A catastrophic water emergency is unfolding across America's heartland and Southwest as reservoir levels plummet to unprecedented lows while major river systems surge with spring runoff. In Texas, critical water supplies face existential threats: Choke Canyon Reservoir stands at barely 24% of normal capacity (49,190 acre-feet versus 201,180 average), while Lake Corpus Christi has collapsed to just 36% of typical levels. Eagle Mountain Reservoir near Fort Worth—a primary water source for millions—holds only 27% of its normal storage. The crisis extends through Oklahoma and Kansas, where Lake Hudson has plummeted to 36% capacity and Tuttle Creek Lake sits at a mere 40% of average storage. Meanwhile, the Ohio River at Old Shawneetown is conveying 259,000 cubic feet per second, creating downstream flooding concerns across Kentucky and Illinois as spring snowmelt combines with recent precipitation events.

The dual emergency arrives as NOAA forecasts a below-average Atlantic hurricane season, offering little relief to drought-stricken regions desperately needing tropical moisture. Outdoor recreation faces widespread disruption: boating access at Texas reservoirs has been curtailed, fishing tournaments cancelled, and municipal water restrictions tightened across the Southern Plains. The situation grows more precarious as Nevada prepares for an intense wildfire season amid persistent drought conditions, while Colorado water managers recall the devastating May 1876 flood—a historic precedent for the volatile drought-to-flood transitions now amplified by climate instability. The Sacramento River's elevated flows at 15,900 cfs and Minnesota River systems running at 16,900 cfs near Jordan signal that while some regions battle excess water, the nation's reservoir crisis represents a fundamental challenge to water security for tens of millions of Americans heading into peak summer demand.

**Critical Data Points:**
- **Texas reservoir emergency**: Multiple major water supplies at 24-36% of normal capacity
- **Kansas water crisis**: Tuttle Creek and Milford Lakes at 40-33% of average storage
- **Major flooding**: Ohio River at 259,000 cfs; Mississippi River systems elevated across Minnesota
- **Wildfire season**: Nevada preparing for heightened risk amid ongoing drought conditions
- **Recreation impacts**: Widespread closures and restrictions across Southern Plains reservoirs
What you see on the map

Every layer that matters,
updated as the day unfolds.

Each layer is built around a real question — what the snow is doing, what the rivers are running at, what the weather's about to throw at you, where you can head this weekend.

Snow
