Diamond Valley Lake offers fishing and light boating on the lake.
A recreation park, aquatic center, visitor center and the Western Science Center along with the lake marina are located on the eastern end of the lake.
A viewpoint, offering views of the pumping station and I/O tower, along with most of the lake is located on the western end of the lake.
To the south of the lake is the Southwestern Riverside County Multi-Species Reserve, a 13,500-acre (5,500 ha) preserve between Diamond Valley Lake and Skinner Reservoir.
The reserve is home to at least 16 sensitive, endangered or threatened native California bird, animal and plant species.

Stocking of the lake with fish began before the reservoir was filled, with a small rearing pond being placed on the bottom of the valley.
The lake has several species of freshwater fish; largemouth bass, smallmouth bass, bluegill, crappie, rainbow trout, striped bass, channel catfish, and shad.
It was also discovered that a small population of flathead catfish were accidentally introduced.
It is considered one of the best fisheries in California.

Much of the area around the lake remains undeveloped and empty.
Original plans included large recreation areas on both the eastern and western end of the lake complete with golf courses, campgrounds, swimming lakes, water parks and other amenities.
The MWD still plans on building the additional recreation facilities, but lack of funding and lack of support from developers has prevented them from doing so.
