Three of us hit the water at about 8:30am. I sure wish Fish and Wildlife would put in a real launch. It takes a person in the water with waders to get the 18' boat off the trailer.
We had heard that the fish were all on the surface so we fished two rods with mono about 100' back (1 3" orange/gold rippin minnow, 1 3" orange rapalla) and a 3rd with a red 000 flasher and kokanee killer. Tipped the front hook on all lures with just a small pinch of worm. In 2 hrs of trolling, we only had 3 fish in the boat, so I put the downriggers down to 30' (with the same set-ups and put the 3rd with leaded line 3 colors out. We had strikes immediately and in the next 2 hours we had our limits.
The fish were kind of small for Rock Lake. Most were Browns around 13-15" with a couple of Rainbows, the biggest which went about 18".
Most of the fish we caught were on the north side of the lake about 2-3 miles up from the launch in water that ranged from 65-150'. Trolled at about 2.2mph. It was a bright, sunny day, but cold as could be. Very little wind today. Only one other boat on the lake, and they came in with limits of similar sized fish right after we did.
This is a great lake to fish!
