  • Officials invite public comment on Rathbun Lake fall releases

    In 2016 in response to stakeholder input, the Corps of Engineers revised its operating guidance for Rathbun Lake.

  • Fall releases from Rathbun Lake unlikely this season

    CENTERVILLE, IA - Present conditions at Rathbun Lake appear to be unfavorable for the U.S. Army of Corps Engineers to conduct a fall water release this year as the pool elevation is currently below the multipurpose level, 904.0 feet. To provide a fall release for the benefit of state and privately managed conservation and recreational areas in the Chariton watershed downstream of Rathbun Lake, the pool elevation needs to be at 905.6 feet or above to have adequate water storage to conduct the fall water release. In addition, the weather forecast for the next 7 days shows little to no precipitation which contributes to the low probability for a fall water release.
