Flooding is causing issues in many parts of Oklahoma. Muskogee County Commissioner Ken Oak says the road across the Fort Gibson dam has been closed as well as roads accessing the road. That's 251A from the west and Highway 80 to the east of the dam.

The Grand River Bridge has also been shut down due to high water.

The Army Corps of Engineers has increased the outflow from Fort Gibson Lake. This is likely to increase the flooding threat to Webbers Falls, but authorities say it can't be put off any longer.

The Grand River Dam Authority Police Department is reminding boaters and others to be very careful on the water due to elevated lake levels. 

“When the lakes are up like this, the topography of the shoreline can change drastically,” said GRDA Police Chief Brian Edwards. “So we are reminding boaters to use extreme caution and especially be aware of their boat wake.”

Edwards said boaters need to be mindful that structures normally above the shoreline may be damaged by boat wakes as well as other wave action.

He said boaters should stay clear of marked buoy areas in front of spillways at Pensacola and Robert S. Kerr Dams.

Edwards also reminded the public that it is illegal to enter floodwater discharge in a spillway area below the dams.

"The rushing waters can be very dangerous and visitors to areas below the spillways need to pay attention to the signage marking 'no trespassing' and restricted areas," he said in a news release.
