I don't do much freshwater fishing, but I don't ever recall seeing the traditional golden colored Walleye getting that large. Am I mistaken?
Walleye will grow up to 36" - at least from my experience - that is the longest one I have ever seen.
The girth and weight can vary dramatically for fish of the same length in walleye.
My brother in law landed a 36" Blue Walleye in another lake nearby Kipawa, that we very carefully measured to make a Replica mount, and then released, we also had 2 different digital scales. One scale said 14lb 2 oz , the other scale said 14lb 1 oz.
This walleye was caught right after the spring spawn, and was very skinny with a giant head, and likely could weigh 5 or ,6 or 7 lbs more if it was caught in late fall or ice fishing.
The couple of walleye in the photos posted were 32" and 33" - still looking for that 36" in Kipawa
Big walleye are very fun to catch but not good to eat really -the meat tends to get a "mushyness" to it after they are over about 5 lbs - the smallest ones are the best eating - here in Kipawa there is a slot size for keepers 14.5"to 20.5"
The best tasting are the 15"ers
Kipawa is a great place for giant Walleye, with the bonus of great eating smaller fish, amazing Smallmouth fishing - hundreds in a day - and good Lake Trout fishing and Northern Pike
