Agricultural drainage practices have transformed the landscape, rivers, and streams across much of Minnesota. Drain tile quickly moves water off the land, drainage ditches quickly move that water to rivers, and quick-rising rivers erode their banks. In Renville County, 90% of the rain that falls is in the Minnesota River within 48 hours. The elimination of wetlands that store water and slow its movement have dramatically changed the landscape.
Limbo Creek is one of the last free-flowing, unditched streams in Renville County. It meanders across the landscape, compared to the straightened ditches whose primary purpose is to move water as quickly as possible. It’s also appropriately named - Limbo Creek’s legal status is literally in limbo. Despite meeting the definition of a “public water,” Limbo Creek has been omitted from the Public Waters Inventory, the list of streams and rivers kept by the State of Minnesota. This means Limbo Creek is vulnerable to becoming a ditch, without the need for a public waters work permit.
Limbo Creek has been proposed for ditch projects several times, going back to the 1970’s. But a new proposal to ditch Limbo Creek and expand its capacity to sluice water quickly to the Minnesota River has emerged. MCEA has worked with farmers, adjacent landowners, and local conservation groups to push for listing Limbo Creek as a public water, and to prevent another addition to the erosion problem in the Minnesota River valley. This erosion is damaging and expensive. In just one example, the City of Mankato is incurring over $10 million in expenses to prevent a major city well from being swallowed by an eroding riverbank.

Key Timeline Events
Renville County approves CD 77 proposal to ditch one mile of Limbo Creek
On November 3, 2020 the Renville County board denied a petition by MCEA for environmental review and then approved a proposal to ditch over one mile of Limbo Creek (called "CD 77 ditch improvement project.") The Minnesota DNR sends a letter prior to and after the action by the county board telling them that Limbo Creek is a protected public water and environmental review of the CD 77 proposal is required before it can be approved.
Minnesota DNR restores Limbo Creek, four other streams to Public Waters Inventory
Minnesota DNR publishes two public notices and proposes to restore Limbo Creek and four other streams in Renville and Polk counties to the Public Waters Inventory (PWI). The notice also establishes that it is public policy that any stream or river meeting the definition of a "public water" is protected as one, even if it is not listed in the PWI. DNR opens a 90-day public comment period on the relisting proposal.
MCEA petitions Minnesota Department of Natural Resources
Petition asks the Minnesota DNR to correct the error in the Public Waters Inventory, and list Limbo Creek as a public water. Public waters are protected from modification without a permit.
DNR removes over 640 miles of waterways from Public Waters Inventory
Included in the order is the deletion of Limbo Creek as a public ditch, leaving Limbo Creek with no protection under Minnesota's public waters laws.
Petition submitted to Renville County for new ditch project in Limbo Creek
Landowners next to Renville County Ditch 77, which flows into Limbo Creek, petition to modify the channel of Limbo Creek to increase water flow.
US Army Corps of Engineers denies federal permit to ditch Limbo Creek
Limbo Creek listed as "public ditch" in Public Waters Inventory
Minnesota’s Public Waters Inventory erroneously lists Limbo Creek as a “public ditch.” This leaves the creek vulnerable to future proposals to turn it into a ditch. This error was never corrected, and Limbo Creek is listed as a ditch in the final PWI issued in 1985.
