Department of Natural Resources Ranger Bart Hendrix said the lake has seen big crowds so far this summer.
"The lake in general is getting busier," he said. "People are saving their vacation money and spending more weekends on the lake."
Hendrix said while no extra patrols are planned, rangers will be out to enforce safety laws, especially life jackets.
"We have had three drownings on the lake this year," he said. "We are taking life jackets very seriously, especially on children."

She said gas prices also are not as high as expected.
"Some people thought we would be seeing $3 gasoline at this time, but it just hasn't happened," she said. "People are not going to miss out on a vacation this year."
