Parkwide general herpetofaunal surveys were conducted in 1991 and 1992 and focused mostly on aquatic habitats. Open areas and forested habitats were surveyed but to a much lesser degree. In addition to the species shown below, there is some question as to the presence of Eumeces skiltonianus (western skink) within the park. Reptile species have also been reported in the parkwide amphibian inventories.
