An Oklahoma Wonder
The Blue River is the largest stream originating in the Arbuckles. Its headwaters begin in the Hunton Anticline and are fed by springs north of Connerville, Oklahoma. It flows 134 miles south to its confluence with the Red River. It is one of only 42 free-flowing medium sized rivers in the U.S. and the only such river in Oklahoma (Benke 1990).

Arbuckle Headwaters & Streams
The Blue River Arbuckle headwaters and medium-sized streams provide habitat for numerous spring-dependent species including the disjunct least darter, redspot chub and southern redbelly dace. These are steep bedrock-dominated streams with step-pool morphology.
At the lower end of the Arbuckle formation, on the granite outcropping, the stream becomes very steep with taller waterfalls and deep pools. This area is part of the Blue River WMA, which is managed for hunting, a bass and sunfish fishery in the summer, and a put-and-take trout fishery in the winter.
Camping and hiking opportunities are also available. The largest population of seaside alder is on the WMA, along the edges of the Blue River and forming islands.
Woodbine & Coastal Plains
The Woodbine and Coastal Plains reaches of the Blue River are in deeper soils and are much more incised than those on the Arbuckles. Channels are more trapezoidal in shape, with sandy substrates. These reaches exhibit a fish assemblage more indicative of coastal plains streams, and also host a population of the American eel (Anguilla rostrata), a catadromous fish.
Rare Seaside Alder
Seaside alder is a rare tree found in south central Oklahoma along the Blue River. It grows on the edge of waterways and in monotypic stands on islands with canopies extending over the water to compete for sun light against taller trees (Schrader and Graves 2002).
Seaside alder grows on stable portions of the floodplains between bankfull and flood-prone elevations.
Unique Fish Species
Arbuckle streams contain many unique and disjunct species, including several disjunct Ozarkian species: the least darter (Etheostoma microperca), redspot chub (Nocomis asper) and southern redbelly dace (Phoxinus erythrogaster) and the ringed crayfish (Orconectes neglectus).
The least darter and redspot chub are dependent upon cool spring discharges, and this relationship is being studied in detail by our parent study by Fisher and Seilheimer (IFIM section, this report).
Blue River Recreation
Arbuckle streams are important from a recreational standpoint. Local residents and tourists use these rivers for leisure fishing, including bass, sunfish and suckers.
Trout has been introduced as a winter put-and-take fishery at the Blue River Wildlife Management Area (WMA), operated by the ODWC. The Blue River WMA is also a popular destination for hiking, camping and picnicking.
