Spring 2022 Full Road Closures

Spring Construction Update:

Starting Monday, May 16, closures on SH-55 between Smiths Ferry and the Rainbow Bridge will shorten from 4-hour closures to 2-hour closures. The new schedule will be 10 a.m. – 12 p.m. Monday – Thursday, and will continue through Thursday, May 26. Outside of those closures, there will still be one-way, alternating traffic with 15-minute delays.
Drivers should still anticipate longer delays once the road reopens at 12 p.m. to allow flaggers to clear queues on either side of the work zone. Once those lines are cleared, there should not be wait times longer that 15 minutes.

We appreciate your patience as we move through another spring season of construction work. To learn more about the spring construction schedule, visit

About the Park

Lake Cascade offers two group camping opportunities, including Snowbank group camp and Osprey Point group yurts, 279 individual campsites in 10 developed campgrounds (with power, sewer, and water at Poison Creek and Ridgeview) two dispersed camping areas with primitive camping, several day use areas, and six boat launch ramps.

Windsurfers and boat sails crisscross Lake Cascade when the afternoon winds kick up. Anglers catch Rainbow Trout, Coho Salmon, or Small-mouth Bass all year long and hikers or mountain bikers traverse a variety of trails within and beyond the park. Whether you’re a beginner or an expert, the nearby North Fork of the Payette River offers world-class white water adventure.

Lake Cascade has as many camping options as it does recreational opportunities with hundreds of campsites ranging from primitive to fully serviced hook-ups. The sites are located along 86 miles of shoreline with beautiful views of Lake Cascade and the North Fork Mountain Range.

Visit the Bureau of Reclamation website for current water levels.

The park is open year round. Reservations are from the Thursday before Memorial Day to Labor Day. In the winter (snow season), camping is limited and outside of reservations, it is based on a first come first serve. Call the park for details.
