GRDA Variance Request from Grand Lake Rule Curve Requirements in 2017

Vinita – The Grand River Dam Authority (GRDA) is submitting a request to the Federal Energy Regulatory Commission (FERC), which proposes a temporary variance to rule curve requirements for Grand Lake elevations for the period August 15 through October 31, 2017. If approved by FERC, GRDA would not be required to lower the elevation of Grand Lake from 744 feet to 741 feet during that period.

As in prior years, GRDA proposes to institute a slightly modified rule curve for the lake’s elevation during this time period to protect safety and property during the peak recreation season of 2017, including Labor Day weekend. The variance request is the same as those granted by FERC in 2015 and 2016.

GRDA intends to file the variance request with FERC on July 10, 2017. To help facilitate this filing date, GRDA requests written comments on this proposal by July 7, 2017. The public can review the variance request on GRDA’s website, Please send your comments via email to Teresa Hicks at Comments can also be sent via U.S. Mail to:
