BOISE, Idaho (AP) — Federal officials in a letter to Idaho Gov. C.L. "Butch" Otter say they'll work within reason to keep Lake Pend Oreille in northern Idaho full into late September.

Otter in a news release Monday says the clarification of operations at Albeni Falls Dam will give greater certainty to area residents about summer lake levels when recreation is a popular.

The letter from David Ponganis of the U.S. Army Corps of Engineers and Greg Delwiche of the Bonneville Power Administration sent Friday is in response to two  letters sent by Otter last year regarding lake-level management.

Federal officials say starting this spring they'll work toward specific objectives detailed in the letter to Otter as they attempt to balance flood control, power generation and fish habitat requirements with recreation desires.
