What's happening across the country today

June

2026
Daily report
The nation faces a stark hydrological divide as late June brings catastrophic flooding to the Central Plains while severe drought conditions tighten their grip across the South and Southwest. Wichita, Kansas experienced a flash flood emergency with multiple vehicles submerged, part of a broader deluge affecting the region—yet paradoxically, three major Kansas reservoirs (Tuttle Creek, Milford, and Perry Lakes) sit at less than half their normal capacity, down 50-70% from average levels. This pattern extends across the Southern Plains, where Texas reservoirs tell a tale of two extremes: East Texas lakes including Toledo Bend and Livingston hold 30-70% above normal following recent heavy rainfall, while drought-stricken reservoirs serving major population centers—Eagle Mountain (Fort Worth), Bridgeport, and the critical Choke Canyon system—languish at 25-30% of typical levels. Lake Eucha in Oklahoma shows the most alarming disparity, currently holding nearly one million times its average storage, suggesting either catastrophic flooding or significant data anomalies requiring immediate verification.

**Critical Conditions:**

- **Immediate Flood Threats**: Ohio River at Old Shawneetown flowing at 259,000 cfs; flash flooding across Kansas persists despite major reservoirs sitting critically low
- **Severe Western Drought**: Arizona's Bartlett and Horseshoe Reservoirs down 30-45% from normal; California's Lake Havasu holding twelve times average suggests Colorado River allocation shifts
- **Wildfire Emergency**: Utah faces "particularly dangerous situation" with Cottonwood Fire raging amid highest wildfire risk of the year across the West
- **Municipal Water Crisis**: Oklahoma City's Lake Hefner and Texas population centers face summer shortfalls with reservoirs 25-75% below normal
- **Flood Watch Expansion**: Cincinnati and Northern Kentucky under flood watch through Saturday; Minnesota and Mississippi River systems running well above seasonal norms
What you see on the map

Every layer that matters,
