RIAC Dredge Potter Moving to Mile 173 UMR

Date: 7/25/22

A re-send from Friday

Worth noting, todays stage at St louis is 3.5, forecasting 3.0 in a few days. LWRP (Low Water Reference Plane) for St Louis is -3.2

With 3.5 on the gage you can add 6.7 feet ( 3.5 minus -3.2) to the soundings on these surveys to get actual depths

The spots marked 3.5 on the surveys ( there are more than a handful near the sailing line)  would be about 10.2 feet of depth today with 3.5 on the St Louis gage
