As mentioned, as long as they are not stocked and there are no signs posting that the area is closed it's state waters and statewide regulations apply.
read this very carefully.... i was fooled into thinking what Skip has stated meant something else, but i was incorrect and upon further review i figured out where i went wrong.
the rule is, and by all means please correct me if i am wrong: all named waters not specifically stated to be OPEN are closed under statewide regulations. this excerpt sheds a bit more light, taken from the anglers guide 2012.
Use this two-step process to determine regulations on a specific waterbody: 1. Check the table on page 12 for the general statewide regulations. (fish species/size/creel limit) 2. Refer to the specific waterbody in the alphabetical listings of Lakes & Ponds (pages 24–33) or Rivers & Streams (pages 36–44) for special site-specific regulations. If no site-specific regulations are listed for a waterbody, statewide regulations apply for seasons, methods, and/or limits. Unless otherwise indicated in the Lakes & Ponds and Rivers & Streams listings: • Lakes and ponds are open year-round. • Rivers & streams are open from 6:00 a.m. on the 3rd Saturday in April through the last day of February (Closed to all fishing from March 1st to 6:00 a.m. on the 3rd Saturday in April
i was fooled in an vaugely unspecified stretch of the housatonic river early last season... and for the previous 6 seasons, annually. a chance encounter with a friendly but somewhat puzzled officer showed me the error of my reasoning this past spring. he was kind enough not to write me a citation, but more so i was straight forward with the man, and explained my confusion. he agreed and mentioned a number of anglers were confused like myself.
the odd part was that i was never in any doubt i was even remotely in the wrong, until we both pulled out anglers guides (which i keep with me just to be safe on things like this!!!), and he showed me the above clause.
