FYI, Swanson Lakes is a WDFW Wildlife Area not a refuge. An early October hunt resulted in Huns for my wife and I. The population was definitely UP from past years. Swanson Lakes and the nearby ponds were bone dry due to the long drought. I heavily suggest a stop M-F at the Wildlife Area main office; the manager, Juli Anderson is doing a super job and is extremely helpful.The WDFW website has a map and info., too.
Twin Lakes, South of Swanson Lakes is managed by the BLM and is hunt able for Huns. The only refuge is around Coffee Pot Lake.
