Per the colorado regulation brochure
COMMON HOOK is any hook or multiple hooks having a common shank. All hooks attached to a manufactured artificial lure shall be considered a common hook
ONE PERSONALLY ATTENDED LINE Each line shall have only three common hooks attached.
PERSONALLY ATTENDED LINE
means a rod and line, hand line or tip-up that is used for fishing and which is under the personal control of a person who is in proximity
to it.
So you can have up to three treble hooks rigged up to your sucker if you want.
