Around the watershed


November delivered an average of 2.09 inches of precipitation to the Great Miami River Watershed 0.91 inches below normal for the month. The high station was Collinsville (3.01 inches), and the low station was Springfield Wastewater Treatment Plant (1.22 inches). As of November 30, the Great Miami River Watershed had received 36.29 inches of precipitation since January, 0.10 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.

Good quality drinking water in the region’s buried valley aquifer remains abundant throughout the Miami Valley, and excessive nutrients continue to threaten water quality in our rivers, according to The Miami Conservancy District’s 2013 Water Resources Report.
