Middle St. Louis River Watershed Culvert Inventory
This culvert inventory is critical for identifying areas where stream crossings are destabilizing stream systems and compromising their ability to effectively transport both water and sediment.
LOCAL LEVERAGED FUNDS
This project will create a culvert inventory database for county and township roads in the southwest portion of St. Louis County that contains the St. Louis River watershed. Data will be used by the County Public Works Department to identify and prioritize stream crossings in need of replacement or increasing upstream storm water retention to reduce the potential for culvert failure during large runoff events, factoring in stream health (fish habitat and passage, sediment transport and hydrologic connection) while protecting infrastructure.
