Hours after officials warned residents of the chances of flooding near Venetian Drive, the Saffin Pond dam gave way, leading to an evacuation for all lake front property owners.

With officials concerned with flood waters heading into Lake Shawnee, emergency vehicles, including fire trucks, ambulances and water rescue vehicles,  were helping to evacuate residents to Camp Jefferson, which was currently being used as a shelter. (Update: Residents were allowed to return to their homes mid-afternoon)

While the Saffin Pond dam has been under construction for a few months, Jefferson Police Captain Eric Wilsusen expressed the township's surprise when the dam gave way.

“This is the big one for now," he said. "No one expected this.”

Several other Jefferson Township roads were flooded and impassable Sunday morning, while other areas lost power after succumbing to the effects of Hurricane Irene.

Gianna S. Rojas of Oak Ridge told Patch in an online comment there is was power on Stoneybrook Lane Sunday morning.

"We had bad flooding from the end of our street [at] StoneyBrook and Linda Lane. Whitecapps in the backyard as water rushes through our yard over the rocks," she said.

At Berkshire Road and Valley Street, a small bridge was eroding, so Berkshire had been closed down.

Berkshire was also closed less than one mile east of Route 15, because of a downed tree that was covering the entire road.

Weldon Road had several very deep puddles. It wasn't closed as of about 11 a.m., but driving on the road was potentially hazardous.
