"The Ohio Department of Natural Resources recently
completed a modernization of the McConnelsville Lock 7 dam.
Because this updated structure passes water more efficiently than
the old dam, the local flow dynamics around the streamgage have
changed. To ensure the forecast remains as accurate as possible,
the National Weather Service and the United States Geological Survey are currently recalibrating the rating curve used to translate river flow into forecasted river heights. We would be pausing everyday forecasts while this recalibration takes place.
WHAT THIS MEANS FOR YOU:
* For Boaters and Recreational Users: 3-to-5 day forecasts for
normal, everyday water levels will be temporarily unavailable.
However, you will still be able to view current river level
observations at all times.
* For Public Safety: The NWS continuously monitors river conditions.
Should the probability of a high water event increase, river
forecasts will immediately resume along with any appropriate
Flood Watches and Warnings."
