Seeker,
Winni is designates as a "Lake Trout and Salmon Water". See pages 22/23 of the NH Fresh Water Fishing Digest linked below:
http://www.wildlife.state.nh.us/Fish..._Digest_07.pdf
It states "October 1 to December 31 - Closed to all trout, salmon, and whitefish".
Have you gotten lucky not getting caught in the past?
