OLIGOTROPHIC LAKES.Oligotrophic defines as such; Low fertility. Walleye will spawn in streams or rivers that are dark and deep enough to support them. Some walleye will spawn in the lake if there is sufficient wind swept rubble or gravel shore line. Sometimes this is not available in an oligotrophic lake, as some are very deep with sheer drop offs. Lake spawning will occur one to two weeks after the river walleye have completed spawning. The females will leave the spawning areas while the males may remain for up to two weeks. Once the walleye leave their spawning areas they will move to deeper water, fifteen to thirty feet deep. The water will be warmer here and they will find forage such as bait fish and immature insects. If the water is deep enough the walleye may remain here through out the summer. In the summer walleye can be found on sloping reefs. The best reefs have weed growth at the top. The walleye will prefer deep water as the water is clear and allows maximum light penetration. The walleye will move to the top of these reefs in low light conditions. A lot of oligotrophic lakes contain ciscos. The walleye will suspend over deep water to take advantage of this high fat forage despite the coldness of the water. During the fall the walleye will move up onto the shallows and feed. This is also the time when the ciscos spawn. As the water gets cooler the walleye will tighten up their schools and will be around sharp breaks in structure. Walleye are hard to find once an oligotrophic lake turns over. The walleye can be anywhere!
