[quote TubeDude] Besides having weed beds a lot of those old lakes also have thriving populations of several different forage species...minnows. Huge difference between those and our sterile reservoirs.

Utah, too, has quite a few native minnow species (as well as introduced minnow species in its rivers and lakes). Those species include--among others--leatherside chubs, speckled dace, least chubs, and redside shiners. The problem is that nonnative fishes have either outcompeted our minnow species or predators have consumed and held their numbers in check. The reality is that are reservoirs in Utah have never been and never will be places where consistent populations of perch and walleye can thrive and coexist. Prey populations is only one aspect of that equation...
