Once upon a time I caught a brown in the White River, below the dam in the proximate location of the state park (Arkansas), that measured 26" - not that big of a trout for those waters - and did not weigh same. In the same waters and on the same outing I also caught a 19" and a 20" and I was surprised that these two smaller trout gave a bigger fight. Some things in the fishing department are hard to figure.
