Recreation was designated as a mission of the Mill Creek Project in 1964. Bennington Lake offers approximately 20 miles of trails for hiking, biking and horseback riding. The Lake is filled to a recreation pool of elevation 1205' above sea level in the spring once the risk of flooding is low. The lake is stocked with rainbow trout by the State of Washington Department of Fish and Wildlife in the spring; however, once the Corps of Engineers water right ends in June the lake elevation begins to drop and no more fish are stocked. The lake is open to vehicle access throughout the year and is open from 6:00 am until 10:00 pm daily.

Rooks Park is a developed day use area. It is open from 7:00 AM to Sunset April 1st to October 15th. After October 15th the gates are closed and the water is shut off, but visitors are welcome to walk in and use the trails. While visiting Rooks Park dogs must be on a leash no longer than 6 feet. Rooks Park has a reservable shelter that costs $50.00 per day to reserve. You can reserve it by visiting recreation.gov or by calling 1-877-444-6777.

The Mill Creek Flood Risk Reduction project was created after the 1931 flood of the City of Walla Walla. The project was completed in 1942 and is comprised of two dams that operate in cooperation to divert and hold flood waters. The Diversion Dam is located at Rooks Park and the Embankment Dam that holds the water is located at Bennington Lake.

The Mill Creek office is located at 3211 Reservoir Rd and is open from 7:00 am until 3:30 pm daily. During the summer, Park Rangers do work later.
