Fishing the White River and North Fork River is always challenging because the river levels rise and fall each day as water is released from Bull Shoals and Norfork dams. Here are two important links from the U.S. Army Corps of Engineers that give anglers accurate, up-to-the-hour information about current river levels. Do not risk wade fishing or boating when the water is running too high.
Water levels above 3,000 cubic feet per second are often dangerous for wade fishing on both rivers, except in select locations. Between 3,000 and 10,000 cubic feet per second, the White River offers some good wading locations along its 99 miles of trout water, but most must be accessed by a boat. Water levels above 10,000 cubic feet per second on the White River should only be fished from a boat, and water levels above 20,000 cubic feet per second are generally too risky for boat angling.
It’s always better to wait for safer water for fishing rather than take a chance fishing water than can be deadly!
