Around the watershed


Cyclists, walkers and others will experience a one-week detour beginning Tuesday, Dec. 2, along the Great Miami River Trail in Dayton between Helena Street and Deeds Point MetroPark. The Miami Conservancy District will be working on the trail under the I-75/State Route 4 overpass. Trail users should travel parallel to the trail on North Bend Boulevard during construction.



MCD is working to help organizations preserve our region’s water through programs such as the Stream Team, which trains volunteers to monitor stream water quality. Learn more about the Partners for the Environment and Stream Team, and help continue to #SpreadtheGood in our community.


October delivered an average of 2.37 inches of precipitation to the Great Miami River Watershed 0.35 inches below the monthly normal. The high station was Collinsville (3.47 inches), and the low station was Saint Paris (1.62 inches). As of October 31, the Great Miami River Watershed had received 34.20 inches of precipitation in 2014 which is 1.01 inches above normal for this point in the calendar year.


Just a reminder, Montgomery County is replacing the Ridge Avenue Bridge so the Stillwater River Bikeway has a short detour through Triangle Park. Trail users are re-routed along the Great Miami River Bikeway between DeWeese Park and the southern tip of Triangle Park. Construction is expected to be completed by September of 2015.



The Downtown Dayton Partnership, Miami Conservancy District, and a team of community partners are seeking an original design to be painted on a concrete floodwall along the Great Miami River.
