Mile 117.9 
Both sides of island 0.6 mile upstream of Fletcher Ford at 
Fletcher Cliff; Lee County, Virginia; TVA map 161 SE, 36° 
36' 16"N, 83° 17'13"W. Collection dates: 8 August 1979, 13 April 
and 21 April 1980, 18 May 1980, 18 June 1980. 
Mile 120.6 
At old ford, 0.4 river mile above unnamed county road bridge 
(county road intersects with county road 661, 0.3 mile northwest 
of bridge); Lee County, Virginia; TVA map 161 SE, 36°37'16"N, 
83°16'50"W. Collection dates: 29 June 1979, 23 April 1980, 16 
May 1980, 16 June 1980. 
the same areas. Qualitative collections were also taken with seines and 
backpack electrofishing units. 
The seine-snorkel technique (Hickman and Saylor 1984) involved 
four snorkelers in a line, moving downstream into a stationary 6-m 
seine with 5-mm bar-mesh. Snorkelers swam abreast of each other while 
bumping and pushing 1.1 -m fiberglass bars along the bottom. Fish were 
thus herded downstream into the seine. 
To insure a standard sampling area (4.9 m x 15.2 m), the snorkel- 
ers’ bars were attached by 16.6-cm lengths of chain. The transect length 
was determined by using a 15.2-m anchored rope. At the start of each 
transect the rope was anchored at the upstream end of the transect, and 
the seine was set at the downstream end. 
Relative abundance estimates were also calculated from transects 
taken with backpack electrofishing gear. The method was similar to that 
used for seine-snorkel transects. 
Fish caught were identified to species, enumerated, and released. A 
voucher specimen of each species, along with any specimens of uncer- 
tain identity, was preserved in 10% formalin and returned to the labora- 
tory for verification. After identification, specimens were stored in 70% 
ethanol and deposited in the TVA reference collection or in one of the 
following museums: Northeast Louisiana University Museum, Florida 
State Museum, Ohio State University Museum of Zoology, U.S. 
National Museum, University of Tennessee Museum, University of Ala- 
bama Ichthyological Collection, or Roanoke College Museum. 
Nomenclature used in this paper follows Robins et al. (1980). 
RESULTS AND DISCUSSION 
A total of 122 species of fish, representing 18 families, were identi- 
fied from more than 107,000 specimens collected in the nine study 
streams (Table 2). The results will be discussed for each river, with 
comments on noteworthy species collected.
