Each year, biologists working on Lake Oahe collect information on fish populations and angler use of those populations. This information helps biologists predict how fishing will be the following year.
Current Lake Oahe walleye regulations include a daily limit of 6 walleye, which may include no more than four walleyes 15 inches or longer and no more than one of those may be 20 inches or longer, year-round. The possession limit for Lake Oahe is 18, which must be obtained with three or more days of fishing.
Walleye fishing usually peaks on Oahe during June and July. Fishing in the upper region usually peaks from late May through June and the middle and lower regions peak during June and July. During peak fishing times, catches of walleye by anglers will be higher in upper and middle Oahe than lower Oahe
The 2004 walleye abundance index, which was about years and lower than the peak of the mid 1990's. The walleye abundance in Lake Oahe increases as you move upstream because of higher natural production of young walleyes in the upper section of the reservoir during most years. The
Walleye condition, or how plump a walleye is at a given length, is a good indicator of growth. The ideal range for the condition index is 90 to 100. Walleyes were generally in the ideal range until 1995-1996 with condition reaching a low in about 2000.
Though water levels in Lake Oahe are low, the quality of the walleye fishery is improving and Game, Fish, and Parks will continue to work hard to maintain access to all areas of the reservoir during 2005.
