Intense Rain Thursday April 20, 2017
The extreme hard rain dumped over an inch of rain in just a few hours in Oakland and Macomb County during the afternoon of April 20, 2017. All that stormwater had to go somewhere – the Red Run Drain .
As the Red Run Drain rose rapidly it submerged the street outfalls, rendering them almost useless, essentially surcharging them as water finds it own level.
Click on the link above (not the picture) and you’ll see the outfall for Ryan Road and nearby neighborhood street drains about 3/4 of the way UNDER the flow of the Red Run Drain. It often becomes completely submerged by 10 feet of water as levels approach the height of the bridge.
