COLLECTING STATIONS

Collecting was done at stations listed below and shown in Fig. 2. Each station was assigned a letter, designating the stream system on which the station was located, and a number which indicates the position of the station on the stream. This number increases progressively upstream from mouth to source. Code letters used are as follows: A&Mdash;Arkansas River; W—Walnut River System; B—Beaver Creek System; C—Big Caney River System; G—Grouse Creek System; M—Middle Caney Creek System; E—Elk River System. All dates are in the year 1956.
