Winton Lake at Winton Woods is now open to recreation, including boating and fishing.

"As cleanup efforts wind down, isolated portions of the lake may be closed temporarily through next week," Great Parks says in a statement. "Guests should obey posted signs."

The Metropolitan Sewer District says a mass of tree roots, grease and "flushable" wipes caused a sewer line to overflow in Winton Woods. The agency is also investigating a second sewage spill elsewhere in the park.
