The Lake Bronson Dam Project

  Current Status (December 2008): Barr Engineering has completed the feasibility study for the Lake Bronson Dam and the study has been submitted to the Minnesota DNR. The alternative being considered for repair of the dam is as follows:

Rebuild Existing Spillway and Allow Embankment Overtopping
The selected option repairs include modifying the existing spillway, replacing the existing gates with new gates that can pass normal and seasonal high flows (flows that are typical for an average snowmelt) through the existing spillway, overlaying the spillway and the downstream concrete apron with reinforced concrete, extending the downstream retaining walls, and adding rock, gravel, and granular filter downstream of the spillway apron. The embankment will be lowered and armored with Roller Compacted Concrete (RCC) to allow safe overtopping by major floods without significant embankment erosion. Public access along County Road 28 will be maintained with this option, with a portion of the road at a lower elevation. 
The complete study and results can be found in the document titled Lake Bronson Dam FS Final Report (.PDF file, 9.6 MB), along with conceptual drawings of the selected alternative.
