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 areas of Gleason Creek and Ditch #15 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.
