5.5 Operations and Maintenance

Activities detailed in this implementation plan will require both ongoing and new operations and maintenance activities in this subwatershed.  These include inspection of erosion-prone Long Lake Creek annually to maintain conveyance capacity and identify erosion that could contribute sediment downstream or impede proper function of the channel, and maintenance activities for existing and proposed capital projects.
