Seminoe Reservoir in Carbon County, Wyoming, was at just under 30% of normal during a recent observation, according to Nebraska Extension educator Gary Stone. The reservoir feeds the North Platte River system, including irrigators downstream.
Stone’s observation came as Nebraska producers and water managers assessed the effects of limited water supplies during the 2026 irrigation season. Nebraska Farmer reported that the reservoir’s low level contributed to a shorter irrigation season and added to concerns about water conditions going into next year.
Water demands compete
The North Platte system serves more than one group of users. Agriculture, municipalities, industry, recreation and expanding urban areas all rely on water, and the demands can overlap when supplies are limited.
Across drought-affected areas of the West, reservoirs have fallen below half capacity or lower in periods of reduced snowpack. The conditions described at Seminoe Reservoir place the North Platte system within that broader water-supply challenge, while the reservoir’s connection to Nebraska makes its level relevant to irrigators farther downstream.
- Seminoe Reservoir was observed at just under 30% of normal.
- The low level contributed to a short irrigation season in 2026.
- Water users include agriculture, municipalities, industry, recreation and urban areas.
For irrigators, the immediate issue is producing crops, forage and livestock with fewer inputs, including less water and energy. Stone’s account described water management as a matter of prioritizing uses and determining how to produce more with constrained supplies.
The water discussion also extends beyond farm operations. At a meeting of cattle producers, a natural resources district director described water security as a concern shared by communities and nations. The account connected shortages of water with food security and with competition among users.
The North Platte River system’s conditions will remain part of planning for the next irrigation season. Stone’s observation provides a recent measure of the reservoir’s level, while the short 2026 season supplies the documented context for concerns about water availability in the year ahead.
