Topaz Lake sits on the California border in western Nevada with half the lake in each state. On the Nevada side is the pleasant town of Topaz Lake. Popular activities at the lake include boating, water skiing, and fishing. Topaz Lake Park on the northeast shore has boat launching facilities, and you can rent aluminum motorized fishing boats at Topaz Landing Boat Rentals. The fishing is great for rainbow trout, brown trout, largemouth bass, and smallmouth bass. The park is also an excellent location to view bald eagles, pelicans, ospreys, and other bird species.
