The walleye prefers water temperatures below 70 F, which are found in the deeper waters of reservoirs during the summer and the cooler rivers feeding, selected reservoirs.
Fish are the predominate food item of adult walleye.
The spawning sites are generally over rocky bottoms such as that found near the riprap of dams or in the headwaters of feeder streams. The female can release from 50,000 to 500,000 adhesive eggs along the shoreline as an accompany male or males fertilize them. The unattended eggs will hatch in 5-9 days. This fish has been stocked in selected areas of the upper Savannah River along with a very close relative, the sauger. The walleye is an excellent sport fish, which is highly regarded for its angling qualities and table value.
