Unnamed Pond near Belt Mountains. Air temp 48 degrees. Gusty winds, overcast. Decided to check out a pond I've been hearing some interesting stories about. Turned out to be not much more than a large farm pond on some state land. Cattle have been using it regularly, and the mud was atrocious. Water had about a foot visibility, and near the bank the water had that brown, cow urine tinge, so I wasn't very optimistic. Nevertheless, the second cast with a small olive bugger hooked a nice, fat 16 inch rainbow. Dang near every cast after that either resulted in a netted fish or a nice strike, and not a single fish under 16 inches. One fat rainbow went almost 20 inches and probably 3+ lbs. Stayed with the streamer for a good 4 hours and finally got bored and tired, fighting both the fish, the mud and the wind. Made a note to return with the pontoon boat. The pond is a good size, but with the toon, I could anchor in the middle and cast to both banks. A real gem in the middle of nowhere. It must be spring fed from under the pond, as there were no visible inlets that held water.
