Around the watershed


The Miami Conservancy District celebrates its 100th anniversary this year. But MCD might never have been formed if not for the determination and perseverance of a few men.


A year-long study by the US Army Corps of Engineers (USACE) validates the economic potential of the Great Miami River corridor, from bringing more tourists and generating additional small businesses to attracting additional workforce and driving larger businesses to the region.


December brought an average of 2.76 inches of precipitation to the Great Miami River Watershed 0.10 inches below normal for the month. The high station was Franklin (3.74 inches), and the low station was Urbana (1.58 inches). Total precipitation for the year 2014 was 39.05 inches which is exactly the long-term annual average for the watershed.


Results from a riverfront recreation study on 99 miles of the Great Miami River validates investment for economic return. Read the report.


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.
