There have been a few published reports that found reproduction by saugeye so they not entirely sterile. However it is very doubtful they would spawn in a pond or most small lakes.

Impact of Introduction: In Normandy Reservoir, Tennessee, saugeye have been reproducing with each other and backcrossing with walleye, compromising the genetic integrity of the natural walleye population. Walleye require specific habitat conditions for spawning and are often displaced by saugeye spawning in the same area. High numbers of saugeye could reduce populations of other gamefish (centrarchids) from which they readily consume (Fiss et al. 1997).
