Lake and River Conditions

NOTICES TO DIABLO AND ROSS LAKE BOATERS

  • Seattle City Light has completed most repairs to docks and facilities at the head of Diablo Lake that had been destroyed or damaged by a 2010 rockslide.


    PORTAGING

  • There is a the new portage dock for all canoe and kayak portage activities (note: do not use the ferry dock). The portage is 1.2 miles over a gravel road, with an elevation gain of 525 feet, elevation loss of 100 feet.

  • Ross Lake Resort also offers a portage service for canoes and kayaks. Itis not possible to portage power boats, or any other boat that can not be carried, between Diablo Lake and Ross Lake. Boaters should be prepared to unload their boats and gear and carry it to the portage truck. There is a phone installed near the ferry dock for visitors to call and request portage service from Ross Lake Resort.

  • The Ross Dam Trail (milepost 134 off State Route 20) can also be used as a portage route to Ross Lake if need be, but it is not recommended, as this trail is a rocky, switchbacking trail that descends one mile and 900 feet to reach the lake.
