I went to my 3 year old nieces birthday today held at a SD County Lake. I found beds everywhere with males posted up on them. The females were staging in deeper water. I saw a few 4-5-6-7lbs females. Then a few larger females roled up. The ranger and I talked about them and agreed they were pushing past 10lbs. I've seen some big Calico (and that's my gage), but these bass were BIG and THICK.
Anyway, check your local SD lake. Bass are in the "mood" so you can throw something at them. Not sure if I'm really into bed fishing, but if the "size" is right, it could be worth the time. These photos only represent a few fish out of 8 large females and about 20 - 1-3lbs males. I took the boat ride with the family and made about 5 sight cast. No hits. Just a lot of CoorsLights.
