Northern Missouri
The Roy Blunt Reservoir is a water project with a road layer
The Roy Blunt Reservoir, formerly the East Locust Creek Reservoir, shows how water supply, county roads, and regional planning meet in Sullivan County.
The Roy Blunt Reservoir is more than a future lake on a map. It is one of the clearest Sullivan County examples of a local project that turns into roads, grants, water planning, and land questions all at once.
The transportation page separates two things that can get blurred together. MoDOT is administering a federal BUILD grant for transportation improvements around the planned reservoir, formerly called East Locust Creek Reservoir. MoDOT is not building the reservoir itself. The reservoir project is a separate cooperative effort involving Sullivan County, the North Central Missouri Regional Water Commission, and USDA’s Natural Resources Conservation Service.
The road details show how real the project is on the ground. Affected Sullivan County routes include 5, N, VV, and Y, with improvements such as new bridges, new pavement, Mid-Lake Road work, and intersection changes. In other words, this is not only a water story. It is also a road-map story.
The water piece explains why the planning reached so far. The federal environmental review frames the reservoir around water supply, water-based recreation, and flood-damage reduction on East Locust Creek. The local sponsor group listed by MoDOT includes Green City, Milan, Public Water Supply District No. 1 of Sullivan County, and Green Castle, so the project is tied to more than one place in the county.
For a reader near Milan, Green City, Green Castle, or rural East Locust Creek, the practical lesson is simple: check the right source for the right question. Road and traffic questions go to MoDOT. Reservoir construction and water-supply questions go to the project sponsor and NRCS record. Land, access, and timing questions should not rest on old word of mouth, because the project has had name changes, grant steps, road phases, and schedule changes.
