When you catch a big Walleye, big meaning over 6-pounds, there is a 95% chance that it’s a female. The big females generally only go into the shallows in the spring where they are up along the shore, in rivers or over sandbars, which are their favorite places to spawn. The smaller males seem to stay in the 2 to 15 foot range all year. The bigger females tend to go deeper then 15 feet. When fishing deep for big mid-summer Walleye fish between 20 and 40 feet deep.

Why do the big females go deep? There are several explanations depending on the size of the lake and how far north the lake is.
1) Bigger females have a larger air bladder, which makes them hyper sensitive to changes in atmospheric pressure. Being deeper makes the adjustment a little easier when the weather changes.
2) Bigger females spend too much energy chasing small bait fish that are found in shallow water. The bigger bait fish that are found is shallow water like perch etc., are hard to swallow as they have defensive spins in their fins. Sucker Minnows, Whitefish, Lake Herring are all found in abundance down deep AND this food source is abundant in Wawang Lake. They are easier to swallow and more rewarding when considering the amount of energy needed to catch them. These deep water bait fish, especially Whitefish, have more oil in their meat thus more calories.
3) A walleye metabolism speeds up in shallow warm water. As a result, the bigger they get, the more food they need to maintain their weight. If the food is not there, they go to deeper cold water so their metabolism slows down. The dangerous thing about this is there is a fine threshold between eating more or conserving energy. If a big Walleye gets to the point where they can not find enough food to maintain their weight, they do get smaller, then they die. As soon as a Walleye gets to the point where they are starting to weaken from lack of food energy, they do not have the energy to catch bait fish and starve to death.
4) In smaller northern lakes, there is a larger population of Pike regularly attack walleye and bigger slower moving females are an easy target. This is another reason why they go deep right after they spawn.
Some Types of Lures to Use on the Big Lake:
When you are Walleye fishing on big water like Wawang Lake, the walleye tend to stay suspended along with the schools of bait fish. Lets say you were on a big part of the lake, , the best thing to do is troll until you come across a deeper school of bait fish and then keep trolling over the bait school.
These schools of bait-fish can be 15 to 40 feet deep and the walleye will be there too. The most popular lures are the Rapala Husky Jerks and the Rattlin’ Fat Rap.
–> 10 to 20 feet deep – Regular Husky Jerks
–> 20 to 40 feet deep – Down Deep Husky Jerk or Down Deep Rattlin’ Fat Rap
Just troll around and use your depth finder to spot schools of fish. To determine how deep you are, the Regular Husky Jerks go down about 1 foot for every 10 feet of line out. The Down Deep Rapalas go down about 3 feet for every 10 feet of line out. So using a Down Deep Rapala, getting down 30 feet deep means you need 100 feet of line out. This is just a general estimate. The speed of your troll will affect how deep the lures will go.
3-Way Swivel Rig:
The best way to fish down deep for Walleye is with 10-pound test line and a 3-way swivel rig. This technique is also excellent for other fish that are right on bottom in the 20 to 60-feet of water.
You need 8 to 10 pound test because thicker line has too much friction with the water and it will be hard to find the bottom. You also need a 1-oz or 2-oz weight, a 3-way swivel and a lure that does not sink. Use an Original floating Rapala, Junior Thunderstick, Countdown Rapala or a worm harness with small spinner blades and a big fat worm.
This rig is smaller than the standard type; You need a 3-foot lead line from the 3-way swivel to the sinker. Then you need a 5 or 6-foot lead line to your lure. Get a strait slow troll going and slowly let out line until your sinker hits the bottom. Then reel up a foot and wait.. Keep those lines tight!
