Built in 1928, Scott Reservoir is an irrigation impoundment on Porter Creek near Pinetop-Lakeside, Arizona, USA. The least developed of the "in town" lakes, trees surround Scott Reservoir. It lies just outside the town limits on the Apache-Sitgreaves National Forests.
Scott Reservoir covers with an average depth of , and lies at altitude. It is usually somewhat turbid, which helps control algae blooms and aquatic weeds.

The lake is stocked with catchable-sized rainbow trout in spring, early summer and fall, and it is occasionally stocked with channel catfish. There are also some largemouth bass.
