What's happening across the country today

June

2026
Daily report
The nation faces a striking water paradox this late June: while several Texas reservoirs surge to dangerous excess—Toledo Bend at 25 times normal capacity, Livingston at 13 times, and Lake Tawakoni doubled—the Southern Plains and Southwest grapple with severe deficits. Kansas reservoirs including Tuttle Creek and Milford Lake sit at half capacity, while critical Texas water supplies like Eagle Mountain (27% of normal), Choke Canyon (29%), and Bridgeport (39%) threaten municipal and agricultural operations. Oklahoma's Lake Hudson has plummeted to 44% of average. Meanwhile, major flooding persists along the Ohio River at Old Shawneetown with flows of 259,000 cubic feet per second, the St. Johns River in Jacksonville, and across the Upper Mississippi basin from St. Paul to Hastings, Minnesota. Flash flooding has trapped vehicles across southern Massachusetts and Rhode Island, with warnings extending into Rockland and New Jersey, while Harrison County continues recovery efforts from recent inundation.

The wildfire crisis compounds these hydrological extremes, with smoke from Utah blazes drifting into Colorado and South Florida experiencing dangerous air quality alongside extreme heat. A fast-moving wildfire near Coulee City, Washington has forced evacuation of Sun Lake Campground. Human-caused ignitions account for most of Utah's current fires, stretching resources thin across the Intermountain West. For outdoor recreation:

- **Water recreation severely impacted** in Kansas and western Texas due to depleted reservoirs; boating and fishing access restricted
- **Flooding closures** affect river access throughout the Ohio and Mississippi River valleys; the Snake River at Hells Canyon Dam flows at 19,200 cfs
- **Air quality warnings** from wildfire smoke compromise outdoor activities across the Four Corners region and Front Range
- **Minimal snowpack** remains outside Alaska, where Imnaviat Creek and Atigun Pass expect 4-6 inches this week
- Avalanche centers across California, Oregon, Wyoming, and Alaska remain in off-season monitoring status
What you see on the map

Every layer that matters,
