The Detroit Lake State Recreation Area is a state park and recreation area in Detroit, Oregon. It is located in the Cascade Mountains.

The Detroit Lake State Recreation Area is best known for providing an excellent entrance to the Detroit Lake. This 400-foot deep reservoir was created through the completion of the construction of the Detroit Dam. It can contain up to 455,000 acre feet when full and has a total shore length of 32 miles. This lake is the main feature of the state park, making the unit known best for all sorts of water sports.

Unfortunately, as of December 19, 2011, the Detroit Lake State Recreation Area has its boat ramp closed to the public until further notice, due to the low water levels.
