The Whitman Lake Hydroelectric Project would be located on the southeast end of Revillagigedo Island in southeastern Alaska, approximately four miles east of Ketchikan, within the Whitman Lake and Achilles Creek watersheds. Whitman Lake was a naturally formed lake prior to impoundment. In 1927 construction of the 39-foot-high, 220-foot-long concrete gravity arch dam (Whitman dam) with a 40-foot-wide Ogee spillway, increased the reservoir’s area to 0.23 square mile (148 acres).
