I find that this in my mind is not clearly defined whether east twin lake is 2 or 3 rod lake, we should get a specific DEEP response:

From CT anglers guide:

Allowable Number of Fishing Lines/Rods
The number of lines (with or without rods) that may be used at one time by
an angler was increased from two lines to three, except for the designated
Trout Management Areas, Wild Trout Management Areas, Trout Parks,
Sea-run Trout Streams and Trophy Trout Streams where the maximum
number of lines will continue to be two.

Statewide regulations for seasons, legal methods, and limits (page 21) apply unless a site-specific regulation is listed for a water body.
