It could be very good occassionally many years ago (when I was young). About the time that muskies were in the lake. One day we were there when a 50 inch musky was caught and brought in to the ramp. Of course muskies are another story, and they're gone now. Back to walleyes, I think the infrequent fishing reports indicate they are still there, but maybe numbers not so high. I haven't fished there in a few years, but Struble being a small lake, I'd probably stay tight lipped myself. Delaware, Susquehanna and even the Schuylkill River in the Fairmount dam tailrace will give you better luck. Blue Marsh Lake also supposed to be a good fishery but a good depthfinder is a must. I have a picture of myself from the late eighties with five walleyes caught from Struble, that's when the fishing was decent.
I hammered that lake in the 80's -90's mostly in spring after eyes opened and again in the fall. Had pretty good info from some co-workers and some of my customers a little later. They all claimed to have caught eyes - not me LOL. I tried trolling, drifting + slip bobbers every bait I could get even ordered wigglers(mayfly larvae) through the bait shop. Lures both trolled and casting, jigs, wading and from a boat. The closest I got was the hatchery truck pulled in 3 times while I was there - I think at the time there were stocking fry and not fingerlings yet.
I agree the rivers are a better shot. They also used to pull some out of the Nock but haven't heard for a while. Blue Marsh is mostly bass guys finding a few, haven't heard of guys targeting them there(would be tuff as they would follow the alewifes).
If we get a major flood around the end of Feb - beginning of March and they release water(from the bottom - not top) the spillway of BM can be good, but it's been several years since.
My mind works like lightning, one brilliant flash and it is gone.
Thanks for all the info guys. Helps allot. I ask because it appears they have stocked the lake over the years but its a gamble it it takes. I've heard allot of good things about the rivers but I'm just in a small 12 foot John boat with two electric motors. I've never fished any of the rivers but I venture to guess the Susquehanna is much like the Mississippi that I used to fish all the time back home in Minnesota. I would not take a John boat out on that river but perhaps you have some different perspective or areas of the rivers that are safe for a boat that small. I'm setup pretty well. two 40lb thrust motors, two batteries. I can stay out in the lakes all day, but have reservation about fishing in the rivers without advise.
I might run up in the afternoon Saturday to Struble and stay through dark. troll around, maybe do some Bass fishing while the little girl catches us some crappies and blue gills. I wont go expecting anything thing. A bad day on the lake with the little girl is still better then most other days.
Do a little searching for Lake Marburg. It's near Hanover, PA. Probably a bit of a drive for you though. It's restricted to 20HP outboards, so you might be okay in your boat. It definitely has a walleye population and from what I've heard, the problem catching them is trying to get your bait past the white perch. I've only been out there a couple times. Caught a walleye first trip, then lots of perch the next trip. My boat has a 50HP outboard, so it's too big for Marburg, and my trolling motor battery won't hold up for a day on the water there. If you click on this link, it should download a PA Fish Comm PFD file to your computer. It gives the status of walleye at Marburg. fishandboat.com/images/reports/2015bio/6x10_13marburg.htm
