The reservoir has a surface area of at full supply level. The surrounding drainage area is .
A full-time staff of about five people supervises and operates this dam and the Rafferty Dam built at the same time.

Operation of the project is governed by an international treaty between Canada and the United States.
Moose Creek Regional Park is a regional park on the east side of the reservoir, north of the dam. The park encompasses about 3/4 of a section, which is about 480 acres.[3] The park is east of Alameda off of Highway 9 and north of Oxbow off of Highway 18.[4] The park features full-service camping, tenting, picnicking, swimming, boating, and fishing.
