Fishing John ,you're right it's the aerators. It's been a long time since I fish that Lake I know there was something about it.
I have tried but did not have luck. That was a few years ago. The lake is aerated; if you walk the trails in winter you can see the unsafe area in the middle of the lake. I don't know about springs but would guess there aren't many if they use an electric pump to keep fish alive through winter.
I'm with you, Pedmo....online documentation says max depth of 6' but being from shore, didn't get a great sense of any depth. I could run a 2' diver with relative ease but a 4' consistently got hung up on bottom weeds.
With the aeration system, I am surprised that there wasn't any clear, open (algae free) areas like a fountain might do in landscaping.
Dobber, Doesn't surprise me. I've fished Indian several times over the years and only caught Bull heads & dink Bluegills and LMB.
How much water depth did you find? The deepest water I've ever found on this lake was 3', above the muck. They cut weeds a few weeks ago. Supposedly they stocked the lake with bluegill, northern, bass & some walleye with the restoration. Befuddles me; why stock walleye in a very shallow, low oxygen lake with very little flow......
71° - 75° F
66° - 70° F
Was hoping with the Hwy 19 construction and being off the beaten path, we'd find some unsuspecting foes. Upon arrival at the Lake (and knowing in advance of the DNR's work a couple years ago), it was pea soup across the whole body. Hoped to get into some bass along the boat launch with all the reeds and didn't find a one. Buddy was bobber/worm fishing for panfish and only caught 3" bullheads en masse.
Direct quote from DNR Fisheries Supervisor David Rowe:
"The DNR and Dane County's Land and Water Resources Department put a chemical into the lake that will kill off the carp but will not hurt any other species in the lake."
Hope this helps...
