Gus Garbe, park ranger at Leech Lake, Federal Dam, Minn., adjusts one of the buoys that marks the channel from the boat ramp to the main body of the lake Sept. 3, 2015. The buoys, which are anchored with a block of concrete, need to be adjusted periodically throughout the recreation season. All buoys are removed prior to the lake freezing and cleaned or repaired during the off-season.
