What I find interesting is walleye are not native to the Potomac River but white perch are. Walleye were introduced into the Potomac in the early 1980's. Since then, they have done quite well and spread from the upper and middle reaches of the river all the way to the tidal portions that run through Washington, DC. It is there in the fall line area that both walleye and white perch spawn. Both do quite well together. It has been shown in studies that white perch feed heavily on fish eggs in the spring. However, many reservoirs where walleye are found have no or very poor spawning areas for walleye to begin with. Throw in white perch and that may very well be the tipping point for walleyes failing to naturally reproduce.
