Boaters in Lake Ontario must continue to obey a 5 mph speed limit within 600 feet of shore until Sept. 2, Gov. Andrew M. Cuomo announced Thursday.
The 5 mph speed limit has always been the rule within 100 feet of the shore, but earlier this year the state extended the "no-wake zone" in response to high water levels and threats of shoreline erosion, which could be worsened by wakes and waves churned up by boats.
The speed restrictions also apply to the St. Lawrence River, which flows out of Lake Ontario.
The Army Corps of Engineers reported Friday that the level of the lake has fallen 8 inches in the past month, but remains 27 inches above its long-term average for the first week of August.
