5.5 Operations and Maintenance

Activities detailed in this implementation plan may require new operations and maintenance activities in this subwatershed.   These include inspecting Minnewashta Creek and the outlet channel from Lake Virginia annually to maintain conveyance capacity and identify erosion that could contribute sediment downstream or impede proper function of the channel and the wetlands with exceptional vegetative diversity monthly during the growing season to determine invasive species.
