Lac Seul is located on the former lake bend of Glacial Lake Agassiz. Owing to this previous lake, much of the bottom of Lac Seul is covered with thick deposits of lacustrine silts and varved clay of varying thickness. The water of Lac Seul is tea colored. In clear water Walleye only feed at dusk and dawn because of their light-sensitive eyes, but because of the tea color of Lac Seul, it provides excellent Walleye and Northern Pike angling opportunities throughout the day.

Lac Seul appreciates some of the finest trophy Northern Pike and Walleye and also provides access to the vast, practically untouched wilderness surrounding it.

When there is a good wind, one strong enough to make the waves slightly choppy, walleye can be found anywhere, because the surface water will attract them with the conditions. Right before a storm or when the sky is dark and the wind is blowing can be one of the best times to catch your limit, because the walleye enjoy feeding in this weather.

Weather can play a part in locating the walleye, but these fish are unpredictable and can not always be pegged so easily. The weather can help you determine where to go and which areas to start with first, for the best chance of catching the trophy size fish or catching your limit. An easy way to locate fish is to use a GPS fish finder, but many anglers do not use this technology, instead using the weather as an indicator of where to start their search for the fish. Falling into the wrong belief that the weather determines this every time can be a big mistake, and can cost you fish. Walleye can be found many times in areas where other anglers have never looked, and this area may go against everything you were taught about walleye, but you may end up a trophy fish anyway. No one tells the walleye where they should be, and these fish are known for their unpredictable nature.

In cooler months the walleye normally move closer to the shore and into shallower water, because the water temperature drops and the skies are normally cloudy and overcast. Weather conditions right before a rain storm or snow storm hits are perfect walleye fishing weather, and the fish really seem to feed aggressively at these times. The weather can be used to help predict where the walleye will be, but it is not definitive proof. To catch walleye, you sometimes have to think outside the box and disregard all the advice you have heard. Head for the spot that no angler will fish, even if it is a shallow bed of weeds on a hot sunny day, and you may get a pleasant surprise.

The fish bite better in windy weather and when skies are overcast, but as many a tournament angler with a trophy walleye will tell you, they still bite no matter what the weather happens to be usually. It all comes down to giving them what they want on the particular day you’re fishing.
