RAPID CITY, S.D. (AP) — Authorities in the Rapid City area are warning of high creek levels and fast-moving currents as releases from Pactola Reservoir increase.

The Bureau of Reclamation and the Corps of Engineers are bumping up the water release Wednesday morning to 450 cubic feet per second.

That could go up to 500 cubic feet per second Thursday, and Pennington County Emergency Management Director Dustin Willett says that hasn't happened since 1965.

Rapid City spokesman Darrell Shoemaker says parts of the city could see flooding, and residents should take caution along the city's bike path. Some flash flooding occurred in Rapid City earlier this week after heavy weekend rains.

KOTA-TV reports that in Hill City, Rushmore Forest Products has had to temporarily shut down its saw mill due to impassable roads for loggers.
