39 acres. This small lake is located 4 1/2 miles south of Black Diamond ( State Hwy 169 ), turn east on SE 400th St. for two miles to Enumclaw/Kanasket Rd, then NE about a mile to Deep Lake entry road. The lake is undeveloped and has a nice county park on it. There is rainbow, cutthroat, and spiny rays including bass. The lake has a public fishing pier (small), a little beach area, and a nice hiking trail around the lake. The boat launch is carry in only with limited parking. This would be an excellent lake to float tube on.
