MCD maintains channel modifications along four tributaries to the Great Miami River. Each of these projects is separate from the main system of dams, levees, and channel modifications.

 

Miller Ditch

MCD owns and maintains a section of Miller Ditch (also known as Bull Run Ditch) between Hyatt Street and the CSX Railroad in Tipp City. This ditch, which enters the river at the north end of the city, was built to divert runoff from undeveloped land west of the Tipp City so it would not flow into the levee-protected area and overwhelm the storm sewer systems. It is not designed to provide flood protection and has not been improved to provide capacity for runoff from new development in the area.

 

Mud Run

Channel modifications along Mud Run were constructed as part of the Miami Villa local protection feature in Huber Heights. MCD maintains 0.8 miles of Mud Run, from the old Miami and Erie Canal north of Chambersburg Road to Fishburg Road. A low levee along the west bank of the creek prevents water from flowing over land and into the Miami Villa local protection feature.

 

Holes Creek

The Holes Creek Addition to the Official Plan is a 0.7-mile modified channel in Miami Township, Moraine and West Carrollton. The improvements begin west of Lamme Road and proceed to the mouth of the creek. The U.S. Army Corps of Engineers, which constructed the existing channel modifications, is developing plans to construct a floodwall north of Holes Creek between State Route 741 and the Norfolk Southern Railroad to protect the neighborhood from flooding.

 

Owl Creek

The Owl Creek addition to the Official Plan is a ditch improvement for local drainage and does not provide a high degree of flood protection to the adjacent areas. The improvements are on 0.5 miles of Owl Creek #2 along the west side of I-75 from Farnsworth Drive to the confluence with Owl Creek, and on 0.4 miles of Owl Creek between I-75 and a point adjacent to Gibbons Road west of Alex Road.
