The Ohio Revised Code outlines how conservancy districts are funded. The Miami Conservancy District (Main District) and two subdistricts (Aquifer Preservation Subdistrict and River Corridor Improvement Subdistrict) are individually funded by local assessments, and the funds are not interchangeable. Miami Conservancy District can also receive funding through grants, agreements and other sources. Learn more
2026 & 2027 Flood Protection Assessments
This assessment is used to operate and maintain the entire flood protection system.
In June 2024, the Conservancy Court voted 6-1 to increase the maintenance rate to 3.35%. The previous rate was 2.19%. Rates can be adjusted annually by the Board of Directors and are subject to approval by the Conservancy Court.
A new methodology is being developed to appraise flood protection benefits and calcuate assessments that will start in 2028.
Other Assessments

Subdistrict – River Corridor Improvement (Recreation)
Communities pay an assessment for maintenance of recreation amenities in their city, township or county. The amenities include bikeways and river activity areas – with improvements such as low dams, portages, river access points, and parking lots.
