High waters, swift currents and downed trees are making the water treacherous along portions of the Saranac River, officials say.
The state Department of Environmental Conservation issued a warning to paddlers and motor boaters on Friday following reports that the Saranac River is running high between Second Pond and the Lower Locks.
DEC Regional Director Betsy Lowe says crews are working to remove trees in the water.
"However, boaters and paddlers should wait until water levels recede before venturing out on this stretch of water," she said.
Snowmelt and rain have increased water levels in area water bodies.
Officials say paddling or boating during the spring is always treacherous, but this year even more so, meaning less experienced recreationists should wait for better conditions.
DEC urges individuals to wear Personal Flotation Devices while on the water and while putting in or taking out watercraft.
