Muraider, unless the unlikely happens, that would be rain or snow, the lake levels will be low. Kab is at the bottom of the rule curve which isn't bad, Rainy on the other hand is well below the rule curve, with their clout and political prowness, I suspect they will draw water to help themselves from our basin, keeping us low. It will take an awful large amount of precip to bail us out by opener, however I don't expect we will be high and dry like some years in the past.

The experimental water curve is working in our favor this year, as they didn't do the drastic draw down as in the years past, prior to the curve. With a little bit of luck most boat harbors will have water. guts

There maybe a reader that may have a better explanation then me, but I'll try.

Kabetogama, which is part of the Namakan basin is similair to a resevoir, there are two dams on the Mn./Canada boder in the Kettle Falls area.

In the past the paper mills open and closed the dam/spillway to generate electricity for the mills, savings them 100's of thousands of dollars. There were seasons that they were greedy, drawing off too much water depending on Spring snow and rain to bring the water levels back up.

The water drawn off the Namakan Basin enters Rainy Lake flows on to Lake of the Woods and supports some mills in Canada. It was not uncommon over the fall and winter months for the Kab lake level to drop 8-10' and somtimes more. That being said, you can see if we didn't get lots of Spring runoff and rain, we would begin the Summer with docks sticking out of the water 8-10', some summers the water would remain low and never get back to normal

About 6-7 years ago, after much debate, rule curves regulating water levels, preventing such drastic draw downs in the future, went into effect. The IJC, representatives from both sides of the border, agreed to keep water levels more consistent in case of abnormal Winter and Spring runoffs, they regulate the draw down at the dams, they now should be adjusting the outflows to correlate with the present and predicted weather patters, as it relates to moisture.

Prior to the rule curve now in place, Kab could have been 3-4 feet lower than it is now, with this curve, if its adhered to, the Namakan basin will have a chance to reach more normal levels, instead of having to start out in the whole so far. Hope the explation helps, guts

      There are two main spawning spots on Vermilion that I know of. I'm near the one on the west end of Vermilion. The walleye haven't been as good on this end yet they don't pull any fish out from here. They've been pulling walleye out of the east end spawning spot in Pike Bay, and for some reason walleye have been doing better over there.   I have no doubt that there are many variables that go into the equation, but you can't ignore that the end they put the 10% back into has been doing better than the one where they leave it alone.

      Are there any updates for the area?  It sounds like crappie fishing is good in the shallows on Fishtrap.  I heard Sham is fighting high waters with no end in sight....

      Trolloni - Do you write it that way to actually troll us?  Creel/lake surveys show Vermilion is very healthy and the DNR continues to use new technology.  It's only going to get better.  If we listened to old, arm-chair QB's, fishing would be as shi#TY as the West side.

      At least10% of all eggs hatched at the Pike River Hatchery are returned to Vermilion waters every year. According to DNR statistics that percentage is usually a much higher survival rate then if they had let the walleyes spawn naturally! I consider that a good trade off! Cliff

      They should not be  going  back to area waters or traded to  other dnr  districts they should go right back into LAKE VERMILLION !!!  Don't ya think its time the dnr   should start to listen  to the paying public, us ! [trappers, hunters,  fisherpeople ,boaters and snowmobilers ]
