Lewis River

For more than 65 years, PacifiCorp has provided public recreation opportunities along the Lewis River. Today, we operate 15 recreation facilities along the river, below Merwin Dam and along the shores of Yale, Merwin and Swift reservoirs. Combined, these recreation areas provide the public with 304 campsites in four campgrounds, 233 picnic sites and nine boat launch locations. Our Lewis River recreation facilities begin at Island Access, approximately two miles east of Woodland, Washington, on State Highway 503, and continue 45 miles upstream to Eagle Cliff Park at the east end of Swift Reservoir.

SPEELYAI PARK CLOSURE - PacifiCorp is closing Speelyai Bay Park on the Merwin Reservoir beginning March 16 through March 17, 2015 (weather dependent) so that contractors can repair a water main leak and complete improvements made to the parking area.

For your enjoyment, the Cresap Bay boat launch will be opened for public boating access to Merwin Reservoir between the hours of 9am and 5pm during the Speelyai closure. 

We appreciate your cooperation.  For more information, please contact 503-813-6666.

ALERT as of March 5, 2015 at 2:30pm - PacifiCorp apologizes for the inconveniences that the technical difficulties with the online Lewis River campground reservation system caused our customers on Sunday, March 1, 2015.

Many customers experienced overcharging for site reservations on their credit/debit card accounts.  Please know that we have received confirmation that cardholders will begin seeing credits on Friday, March 6, 2015.

If, after Monday, March 9, 2015, your bank statement still shows an overcharge, please contact us at 877-372-8077 or via email at li.overdrafts@gmail.com

In addition, many customers are also uncertain about their reservation status, after not receiving the confirmation emails which serve as their check-in documentation.  We received confirmation that all customers who made a reservation on Sunday, March 1st were re-sent a confirmation to ensure receipt of the documentation needed.  These reservation confirmations were mailed on March 4, 2015.

Lastly, the $5 reservation booking fee and the $5 fee associated with cancellations and changes to reservations will be waived for transactions and changes made the week of March 1-7 as a courtesy to our customers.
