A spring in North Central Florida finally opened for swimming this summer.
Management at Otter Springs in Gilchrist County had to close the park for swimming because of duckweed.
The green, leafy-looking plant floats all over the top of water and could make swimming dangerous.
Park Manager Nancy Nieman says flooding on the Suwannee River earlier this year was to blame.
"When it came in -- the river came in the springs, it just brought all the duckweed in with it," Nieman said.
The park is now open for swimming.
The springs stay a cool 72 degrees year-round.
