CODK S FOR FISHES' USE 01' REACH 



Codes indicating single use or dominant use: 



L = Resident throughout life cycle 



A = Spawning elsewhere (Includes hatchery fish) — spends part or most of life 

 In reach 



H = Spawning and hatching — young promptly move downstream 



.1 = Spawning and nursery to subadult 



C = Passing through — species uses reach as a corridor to migrate upstream and 

 return downstream 



F = Feeding run 



N = No use (in connection with abundance codes M, N md P) 



Z = Use undetermined 



Codes that are combinations of the above codes to indicate more than one populatio n 

 of a species . 



R = L plus H or J 



P = C plus L, A, H or J 



S = H and J combined 



Any other combination: Code entered for dominant use 



ES THETICS RATINGS . Esthetics were rated 1 (low) through 5 (high). Features that 

 detract from esthetics Include: pollution, dewaterlng, channelization, riprap 

 (particularly car bodies and discarded building materials), mine tailings, a busy 

 highway along stream and severe land abuse. As a guide: 



1 - A stream with low esthetic qualities. 



2 - A stream and area with fair esthetics qualities. 



3 - A water with natural beauty but of a more common type that listed under 



4 and 5. A clean stream in an attractive setting. 



4 - A water comparable to 5 except that it may lack pristine characteristics. 



Presence of human development such as roads, farms, etc., usually comprise 

 the difference between 4 and 5. 



5 - A water of outstanding natural beauty In a pristine setting.
