Fishing Info for Rock Lake

Rock Lake is the deepest and largest of all scabland lakes left behind from the Missoula Floods, and holds that distinction for all of eastern Washington. At its deepest, it is more than 360 feet (110 m) deep, although the official measurement is uncertain. The lake is over 7 miles (11 km) long and averages 1 mile (1.6 km) in width, and is accessible via a solitary landing area located on the south end. The rest of the shoreline is inaccessible to vehicles, other than a few private properties. Located approximately 30 miles (48 km) south of Cheney, Rock Lake is in a moderately remote location. Other towns in the area include Sprague, St. John, and Rosalia, although all are a number of miles away. Rock Lake receives the majority of its water from Rock Creek, which further downstream is a tributary of the Palouse River, as well as Negro Creek. The lake is approximately 7 miles (11 km) long and 1-mile (1.6 km) wide and has a wildly varying depth with steep drop offs that reach over 300 feet. About half a mile from the boat launch, the lakes characteristic geography can be seen, with its high basalt cliff walls on either side with rock pillars and spires protruding from the bottom of the lake. The steep basalt cliffs and stone pinnacles that can rupture a hull and a lack of shoreline coupled with the wind tunnel effect with the regions notable Palouse winds has led to many deaths on the lake. In addition to the perils in the lake, the banks of the lake are also habitat for rattlesnakes in the spring and summer months.
