Around the watershed


Cyclists will soon have a smoother ride along parts of the Great Miami River Recreation Trail. Construction of four sections of the trail is set to begin July 28.


June brought an average of 5.95 inches of precipitation in the Great Miami River Watershed 1.88 inches above normal for the month. The high station was Lockington Dam (9.15 inches), and the low station was Englewood Dam (3.41 inches). As of the end of June, the Great Miami River Watershed had received 22.99 inches of precipitation in 2014 which is 2.73 inches above normal for this point in the 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.


Great story about the Great Miami River Trail.


MCD dams and levees prevented additional flooding during last night's intense rainfall, which closed parts of I-70 and I-75.
