Jeff Holmes posted a good report on Rock Lake. I only fished this lake once and it was about 15 years ago, but it sounds like the ramp hasn't changed a bit... Rock Lake is a fun one to fish, but I tend to disagree to some degree with Jeff's suggestion that it could become a much bigger "name" kind of place if the ramp were upgraded and other species were introduced... Rock lake has two nice bays (narrow but rich) not too far from the ramp... One just to the left after leaving the ramp and one to the right further down... there is a shallow flat on the right about half way up the lake but it doesn't extend very far out into the lake... Other than that, except for the extreme south end the lake
has steep bottom slopes and narrow littoral zones and the primary food source for any kind of major fishery would have to be "pelagic" in nature... that is to say.. suspended, open water kinds of plankton eaters and the predators that prey upon them...


When I fished the lake I had a couple of good hits from smallmouth bass in the bays mentioned earlier, but ended up bringing home 3 or 4 15" class brown trout I caught casting spinners to the rip rap near the north end of the lake. The trout had been feeding on crayfish and were rather thin as I recall....

I would classify Rock Lake as "oligotrophic"... that is to say.. deep, clear, and not exceptionally productive.... I think it will tend to crank out large fish.. but there will never be very many of them, because the food supply to feed them just isn't there...... I think the "poor condition" of the ramp is kind of a positive because it tends to keep the pressure down. In other words it means that those who can launch and fish, will have a much greater opportunity to catch the fish that are there... and, thanks to Jeff's report, I may be headed there soon to cash in...
