Try howard s. slough in hooper.
You should be able to get a 30 yard shot fairly easily. My son killed his there this year and it was a 35 yard shot on the second outing after swans this season. Be out there 10 minutes before shooting light and wait for them to come off the roost. They all get up at once and fly over the west dikes. 15 yard shots are not hard to come by if your "lucky" and standing where they decide to fly over. He killed his swan last year over 13- 13 gallon white trash bags. They were landing in them.
