<P> Many fossils of rabbits, rodents and pond turtles, as well as coyotes, deer and the Black bear, have been recovered as well . One of the most common animals identified from the Diamond Valley Lake site by San Bernardino County Museum scientists was the extinct American mastodon, Mammut americanum . In North American paleontology, mastodons are thought to have been solitary forest - dwelling browsers . The abundance of mastodons in the fossil record from the site suggests that, during the last Ice Age, the Diamond Valley Lake site was more wooded or forested than today . Fossil remains of ponderosa pine and manzanita recovered from the site lend credence to this interpretation . Radiometric dating of fossil plants from the Diamond Valley Lake site confirms an age range of less than 13,000 years ago to more than 60,000 years ago for these fossils . </P> <P> 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 . </P> <P> 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 is considered one of the best fisheries in California . </P> <P> 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 . </P>
