Bruce, Lake Housatonic was the first of the three Housy impoundments to get walleye fingerlings going back to the start of the program in the 90s but it was never proved to be successful during electro-shocking trips. Myself and RobertV fished it hard a few times and Robert did even more so and we could never pattern a reliable bite. We caught more and bigger walleye below the Derby dam at the confluence with the Naugy, that is why I offered the opinion that maybe we were losing the fingerlings over the Derby dam. Walleye will always move to active water flow, they are really a big river fish and in lakes will congregate in front of river mouths, outlets, dams, etc.
So a couple of years ago the Inland Fisheries group decided to try Lake Zoar since it had a history of successful walleye activity over the years. That is why Zoar is the focus now getting some 9,000 or more walleye fingerlings each Fall. Whether this will be successful or not remains to be seen.
The only walleye water that gets any publicity and feedback is Squantz Pond. The DEEP can't survey each of these waters every year so they rely on fishermen to give reports on sites like CTF. Walleye fishermen are more secretive than native brookie guys so getting info is hard. If you have good input then link in with Inland Fisheries and speak privately with Tim Barry, Bob Jacobs or Peter Aarrestad and let them know what is happening on your trips. Your input is very important to these biologists.
