During a recent meeting of the Johnson County Commission, Lake DeSmet Operations Manager Paul Mavrakis presented a comprehensive update on the reservoir’s water year. He noted that the lake’s elevation on October 1 stood at 4,604.46 feet – the lowest reading he has recorded in his tenure, and possibly the lowest ever measured.
Current Reservoir Conditions
Despite the historic low elevation, Mavrakis emphasized that Lake DeSmet remains at 87% of full capacity. In comparison, nearby Keeble Reservoir is operating at just 42% of its capacity, while the Pathfinder Reservoir to the south, which holds a million acre‑feet, is down to 17%. “We’re in great shape compared to what some of the other reservoirs are,” Mavrakis said, underscoring the relative health of the local water supply.
Release and Irrigation Schedule
All water releases from Lake DeSmet were halted on October 1. The year saw an unusually early and extended release period, beginning on May 12 rather than the typical July start. The previous year’s releases did not begin until July 3. This longer release window supported extensive irrigation across the county.
In a notable shift, the Operations Department leased 2,187 acre‑feet of water for irrigation purposes – a practice not undertaken in prior years. This lease reflects the county’s proactive approach to meeting agricultural water needs while managing limited supplies.
Implications for Residents and Farmers
The commission’s update reassured local farmers that the county is taking decisive steps to allocate water responsibly. By leasing water specifically for irrigation, the department aims to sustain crop production without compromising the reservoir’s overall stability.
Residents were also reminded that water usage restrictions remain in effect, and that the county will continue to monitor lake levels closely throughout the remainder of the water year. The commission plans to provide further updates as conditions evolve, ensuring transparency and community involvement.
Looking Ahead
While the low elevation is a cause for vigilance, the relative fullness of Lake DeSmet compared to neighboring reservoirs offers a measure of confidence. The commission’s early release schedule and new irrigation lease demonstrate a commitment to balancing agricultural demands with long‑term water stewardship.
Commission members encouraged citizens to stay informed through county communications and to support water‑conservation initiatives that protect this vital resource for future generations.
