However, in 1966 all mussel fishing was done in the lower 87 miles of the river between Beards- town and its mouth. This was the only known continuous stretch of the river containing a sufficient number of mussel beds large enough to attract commercial clammers in 1966 (Fig. 16). The loca- tions of the beds fished commercially in 1966 are given in Table A-26. In addition, three-ridges occurred abun- dantly enough in 1966 just below Lower Peori
