1).— BASIN OF THE WASHITA. 
IX. — WASHITA RIVER. 
The Ouachita or Washita River is one of the largest streams in southwestern 
Arkansas. It rises in the southern range of the Ozark Mountains, and empties into 
the Mississippi Eiver. The head waters of tlie Ouachita and of its tributaries are 
swift-flowing streams of clear water. Their bottoms are rocky and gravelly. 
The Ouachita was visited near Crystal Bpriugs, Ark. Most of the seining was done 
at the ford. Above and below the ford the water was too deep for our nets. In the 
deep places large rocks were numerous, and the bottoms less gravelly than in the 
shallower water. The current of the Ouachita was less swift than in any of its tribu- 
taries. 
The tributaries of the Ouachita examined are all much alike in physical charac- 
teristics. The Caddo River was the largest visited. The South Fork of the Ouachita 
next in size, Mazarn and Myers Creeks being rather small. 
The Caddo River was seined at Caddo Gap and near Black Springs, and also in 
two small tributaries between these iioiuts. The Caddo is a beautiful stream, but 
evidently contains few fishes and few species. Near Black Spring the Caddo divTdes 
itself into several small streams. This affords excellent opportunities for collecting, 
but fishes were found in fewer numbers than in any other stream in which we collected 
during the summer. Temperature, TG® Fah. 
The South Forh of the Ouachita was seined near Mount Ida. This stream afibrded 
as favorable opportunities as did the Caddo, especially in the long deep holes. The 
strata of rock are nearly vertical, and lying across the stream, form by unequal wear 
a series of ridges and furrows in the shallower places. The stream varies in width 
from 40 to 70 feet, and the water is from 1 to 5 feet or more in depth. In the deeper 
holes were much pond weeds aud grass, which made hiding places for black bass (ilf. 
dolomieu, M. sahnoides) and pickerel {Lucius vermiculattts), which seemed rather com- 
mon. More fishes were found in this stream than in the Caddo. The temperature 
was 74° Fah. 
The llazarnis a tributary of the Ouachita, and Myers'^ Creek flows into the Mazarn. 
These streams were examined near Myers. Neither is large, and neither contained 
many fishes. 
The West and Middle Forks of the Saline are both about 24 miles east of Hot Springs.
