Made it out to Keyhole reservoir yesterday which is about 45 miles away. We were fishing by 8:15 am. Still early season here. Surface temp was 42 when we arrived. The fish we were catching were mostly over 40 feet deep. 3 of us in the boat caught 42 fish if my count was correct. 1 pike and a few perch, but mostly walleye. We kept 15. Limit is 6 each. Lots of smaller ones. Biggest was 17 inches. Quit around 6 and headed home. Dinner was fresh walleye. One of the best eating fish there is. Caught them mostly on a 1/4 oz jig with a minnow.
