District Parks


Walla Walla District - Recreation

As the nation’s largest federal provider of outdoor recreation, the U.S. Army Corps of Engineers (USACE) provides an abundance of recreational resources and opportunities at more than 400 operating lakes and river projects in the United States.  The Walla Walla District includes eight operating projects located in Washington, Oregon and Idaho. Every day, we are working with our partners and the public to manage, improve and preserve the precious land and water resources associated with the Walla Walla District. On this website you will find information about the diverse activities and facilities available for all kinds of recreation along the Snake, Columbia, Boise, and Clearwater Rivers, as well as Mill Creek located in Walla Walla.

The Walla Walla District operates 37 recreation areas that include visitor centers, campgrounds, picnic areas, playgrounds, beaches, marinas, boat launches, day-use parks and nature trails. There are also concession areas and more than 30 recreation areas operated by other government or private agencies at our lakes. The Walla Walla District also provides hunting opportunities on approximately 20,000 acres of public land. Each year, Walla Walla District operating projects host nearly 8 million visitors who come to enjoy the many recreational opportunities available at our rivers and lakes. Whether it is fishing, camping, boating, picnicking, swimming, sight-seeing, bird watching, hunting or a variety of other recreation activities, Walla Walla District has it all so bring the whole family and enjoy the outdoors. Whatever your favorite outdoor activity, one thing is certain: recreation can enrich your life. Visit one of our recreation areas to connect with nature and create unforgettable memories.

Remember to always wear your life jacket when riding in a boat. Just like a car's seat belt, your life jacket won’t work if you don't wear it.
