"First dam" Clarification
The link I provided shows that there are far more waters open year-round than just those listed in the previous posts.
As far as "first dam" or "first bridge" - they are speaking of the first one you come to as you go upstream. Not the first one at the headwaters of that river.
This is what it says in the regulation booklet. Maybe it is changing this year but I follow what is in the booklet unless posted at access points.
This page sorts it out quite nicely:
This forum is an awesome tool to get useful information about gear and tactics, but one of the worst places you can ask about laws. 50 different people will provide you with 50 different OPINIONS (not facts), and one person will have actually read the regs. Up to you to figure out who that person is.
Best to call the warden if the regs pamphlet is confusing.
if they have different regulations for the main river or body of water. then they usually give you the city where the dam or land marker and then if the regulations for up stream or down stream or some have compass direction ( north, south, east, and west) of the land marker.
ex:The daily bag limit on catfish is 10. The season for catfish is open all year except from the Prairie du Sac Dam downstream to the railroad bridge at Sauk City where the open season is May 3 through November 30. From the Wisconsin Dells Dam upstream, only one northern pike may be kept and it must be at least 32". Upstream from the Prairie du Sac Dam, walleye and sauger from 15" but less than 20" and only one over 28" may be kept. Below the Prairie du Sac Dam, walleye must be at least 18" and sauger or hybrids must be at least 15"and the daily bag limit is 3 in total.
In the future you'll probably get better regulation advice by contacting a game warden in the area you plan to fish then anywhere else. Hope this helps.
If so that makes sense, however I'm strictly referring to just a river system (or a stretch of it). It is open year round for fishing, however there are certain regulations that are in effect "upstream to the first dam or highway bridge". So my question is which stretch of the river the regulations are in effect for. I want to assume that it is in effect for the whole river upstream to the very first dam, regardless of how many dams there are.
