Weather experts say between 4 and 5 inches of rain fell on Butler County between Friday and Saturday.

David Shallenberger, meteorologist with the National Weather Service of Pittsburgh, said that amount of rainfall is in-line with conditions that normally occur this time of the year.

“We have high pressure off in the east and southeast. That pretty much lines storms up as they're moving from the southwest to the northeast,” Shallenberger said. “A lot of times, storms will move over the same areas when that happens.”

Shallenberger said despite the pattern, multiple thunderstorm warnings and flash flood warnings, no significant damage or flooding was reported in Butler County.

According to collected county dispatch reports between 3 p.m. Friday and 8 p.m. Saturday, there were 32 calls for downed power lines, two for vehicle crashes and two calls for flooding.

The only water-level tracking on the National Weather Service's site, is one piece of Muddy Creek that feeds into the north-end of Lake Arthur.

According to those measurements, Muddy Creek rose less than 1 foot over the weekend. As of 3 p.m. Sunday, the creek was at a height of 3.36 feet. On Thursday, the creek was noted at 2.85 feet.

“We had some significant flooding in Mercer and Venango (counties),” he said. “There weren't a lot of reports from Butler County.”

However other streams increased to significant levels.

According to tracking of the Allegheny River in Parker, the water rose more than 7 feet since 4 p.m. Friday, when it was observed at 5.69 feet. By Saturday, the river rose to 7.87 feet, and by noon Sunday, levels reached a peak of 13.03 feet, before descending into the 12-foot range by late afternoon.

According to information about that area, the service noted impacts generally begin around 13.9 feet and flood stage is reached at 20 feet.

A flood stage, which is not the same as areal flooding, is when water levels rise enough to cover large portions of land that are not normally covered by water and begin to create a hazard. Areal flooding is water built up gradually from prolonged moderate to heavy rainfall and affects low-lying areas.

The impacts of the Parker report were reflected in neighboring East Brady, where its Riverfest event took yet another hit.

This year's Riverfest had been modified to one day and for the most part continued. The event did postpone its Anything That Floats event and a scavenger hunt to Sept. 4 due to the risen water levels.

The event still featured crafters, food vendors and games for children, and a fireworks display still made it into the sky.

“We apologize for the inconvenience and the overall confusion and moving around of Riverfest this year,” said the organizer on the event's Facebook page. “We are still planning on the Anything That Floats race and scavenger hunt over Labor Day weekend. Again thank you for your continued support.”
