PROJECT ALERT NOTICE (OH) Minor flooding in Ohio

Date: Mon, 10 Sep 2018 11:13:38 EDT

Summary: Minor flooding in Ohio

The extratropical remnants of Gordon dropped widespread 2-4 inches of rain in a 72 hour period throughout southern and southwestern Ohio. A few spots in the Cincinnati Ohio area received upwards of 7 inches of rain in that same time period due to convective cells ahead of Gordon.

Antecedent moisture conditions in Ohio were fairly dry, therefore flooding was only in the minor category (NWS terminology).

Major river basins that were affected were the Great Miami and Little Miami river basins in southwestern Ohio as well as smaller drainage basins (White Oak and Ohio Brush) in extreme southern Ohio and the Licking River basin east of Columbus. The highest flow measurement was captured at White Oak Creek above Georgetown in southern Ohio.

USGS has three crews (6 people in total) out in response to this flooding. One crew is covering southern and southwestern Ohio (Little Miami River basin), another crew is capturing rating gaps in the Licking River basin. One crew is in southeastern Ohio as part of a regularly scheduled field trip. Additionally, the Miami Conservancy District has deployed one crew (2 people) to obtain measurements in the Great Miami River basin.

USGS has been in contact with the Miami Conservancy District as well as the Ohio Water Development Authority.
