Lower Mountain Fork

The Lower Mountain Fork River Foundation (LMFRF) was founded in 2002 for the sole purpose of enhancement and improvement of the trout fisheries of the lower Mountain Fork River. The LMFRF donates directly to the Oklahoma Department of Wildlife Conservation (ODWC) by funding particular projects which will improve trout habitat.

ODWC is currently working on a study of the water quality in the lake above the stream, to determine ways to create colder water flow into the Lower Mountain Fork.

White River

The White River in Arkansas, along with the Norfork River, have been experiencing low dissolved oxygen (DO) levels, and are seeking "impaired river" status with the EPA to provide funding to research the problem.  Trout typically require 6 ppm of DO, and the water coming out of Bull Shoals dam during the summer frequently experiences DO of only 1.4 to 1.6 ppm, resulting in fish kills near the dam, and impaired oxygen levels downstream as well.
