Caswell Memorial State Park is a state park in California , United States, which preserves a riparian forest along the Stanislaus River. It is located in the south of San Joaquin County, southwest of the town of Ripon. Riparian Oak Woodland, located in this park, is under threat and the park is trying to protect it. It once flourished in the Central Valley of California. Caswell is also home to a number of endangered species. The park of 258 acres (104 ha) was established in 1952.


The average temperature is between 45–50 ° F (7–10 ° C) in the winter and between 85–100 ° F (29–38 ° C) in the summer. In summer, it is common to exceed 100 ° F (38 ° C) for several consecutive days. This park was named after the landowner, Thomas Caswell. He enjoyed this beautiful forest, and he wanted to preserve it. In the 1950s, 134 acres (54 ha) of this forest had been donated by his children and grandchildren to California before it was opened to the public as a state park in 1958.


The park is located along the Stanislaus River near the town of Ripon, California. The park protects a fine example of the endangered and still declining riparian oak forest that once flourished throughout the Central Valley of California. Caswell is home to a number of endangered animal species, including the riparian brush rabbit, which is not known to occur anywhere else.


The native Americans who lived along this river and collected acorns from these ancient groves were Yokuts. At the beginning of the 1800s, Spanish explorers crossed this area, and fur trappers found the river bountiful.

Additional donations and state purchases have brought Caswell to its current size of 258 acres. Caswell Memorial State Park was opened to the public in 1958.
