Sandusky River crested Tuesday evening, and the water level was expected to drop by more than a foot by this evening.
The crest at 7 p.m. Tuesday was 10.62 feet, which would be eighth on the list of historical crests for the river in Tiffin. The crest of 11.83 feet Feb. 8, 2008, is fifth on the National Weather Service's list.
The weather service predicted the river would drop to 10.6 feet by 1 a.m. today and 9.4 feet by 7 p.m. today.
Dan Stahl, director of Seneca County Emergency Management Agency, said officials were braced for the worst, and it didn't happen.
"That is a very good thing," he said.
Stahl said his office staff, with assistance from Seneca County's Community Emergency Response Team, spent a few hours taking an assessment Tuesday of areas that had been damaged by flooding.
Properties are rated as "destroyed," "major damage," "minor damage" and "affected" during the assessment. An outbuilding was destroyed, he said.
The information is passed on to Ohio EMA and American Red Cross, he said.
"There was no additional flooding today," he said.
National Weather Service extended the flood warning for Sandusky River in Tiffin until Thursday afternoon. Its forecast for the weekend includes a chance of precipitation.
