Diefenbaker Lake is one of Saskatchewan's best fisheries. This sprawling, 225 kilometer-long reservoir has hundreds of great fishing spots, diverse habitat, and the fish and environment to challenge every skill level and style of angler. From rainbow trout to pike, Lake Diefenbaker supports several several species of fish. Walleye, burbot and pike are just a few of the other fish species thriving in this vase waterbody. From derbies to quieter fishing spots, Diefenbaker Lake has everything an angler could want. This introduction is meant to be a general overview of this large and diverse lake.

DERBIES

There are three major fishing derbies that take place annually on Lake Diefenbaker, with big money prizes at stake. The Lake Diefenbaker Walleye Classic takes place during the last weekend in May. This major tournament is part of the Saskatchewan Walleye Trail and carries a first place prize of $10,000. The weigh-in and boat launch are a Coteau Bay. The Riverhurst Walleye Classic is a catch-and-release tournament that takes place on Father’s Day weekend each year. The Sask Landing International is also part of the Saskatchewan Walleye Trail. This highly popular tournament takes place from July 17 to 19, 2015.

FLY FISHING

Canada Freshwater Fishing states that, "in the course of the springtime, Lake Diefenbaker often floods. This flooding generates pools of water which are referred to as coulees [where] walleye usually go. These walleye are generally tempted by fishermen who use in-line spinner, casting jigs, and crankbaits. These coulees and shore fishing opportunities should not be regarded as simply for the lure angler. In fact, walleye fishing on the fly can be some of the best that Saskatchewan has to offer. This method of fishing walleye has yet to hit the mainstream, however, those who fly fish for rainbow trout know that any fish that can be caught, can be caught with a fly.

Some flies worth considering for walleye are Streamer patterns, leeches and mayfly nymphs. Deceivers are especially popular among walleye fly anglers. Aim for sizes larger than you would for rainbow trout; often, minnow-shaped flies will be particularly effective. Walleye will go after larger prey and will chase it down rather than wait for it.

WALLEYE

For walleye fishing with both flies and lures, the conditions of Lake Diefenbaker are ideal. Walleye rely on wind (among other things) to keep themselves hidden from both predators and prey. Lake Diefenbaker is prone to heavy winds and wave action that walleye love. Along with wind, the best conditions for walleye are cloudy days and other lowlight conditions, especially darkness. Walleye are far more active at night than they are during the day, and if you are feeling adventurous, the time between 10:00pm and 3:00am is ideal. Just make sure you are very familiar with your fishing locations before you attempt this. If you are not a night fisher, take heart. The times right around sunrise and sunset can also be productive.
