When the job of classifying West Virginia’s trout streams was undertaken, the classication of stocked streams was decided on as a
beginning point. e number of streams stocked at that time was 154. Since the project was initiated, circumstances that varied the number
of streams to be classied are as follows:
1. Additions and/or deletions to the stocked stream list.
2. Necessity of rating native and/or wild trout streams as a means of protection against mining, dredging or proposed
road construction.
3. Several sections in particular streams had to be classied independent of one another. Stream ratings oen varied from one section
to another due to eects from local springs, tributaries or specic pollution discharges.
4. Tailwaters have been deleted from the classication list. In a tailwater regime, temperature and water quality are articial and their
classication would not place them in a management class that would reect actual trout potential.
e classication system has provided a means for evaluating West Virginia’s trout stocking policy. e recent removal of ve small streams
from the stocking list, that were determined to have a shable wild or native population, is an example of how this system is being utilized.
ree streams, being repeatedly dredged within the stocked sections, have been removed from the stocking list based on the quality of
habitat. ree streams have been added to the stocking list which were classied as management class three. Also, several streams were
found to be better suited for trout than previously expected, changing the stocking status from a warmwater stream to a Coldwater stream.
More trout were stocked and shermen were allowed to creel six trout instead of four.

e numerical rating of eight parameters for each stream are totaled and the stream is classied as one of the four following
management classes.
Class 1. Rating of 22-30 A stream which would be expected to have a native or wild trout population. No trout stockings
should be made in these streams. If trout are not present, consideration will be given to establishing
them by stream reclamation and ngerling stockings.
Class 2. Rating of 16-21 A stream which should have trout carryover and may have some successful trout spawning. Such
streams should receive ngerling stockings and/or “put-and-take” stockings.
Class 3. Rating of 7-15 A stream capable of supporting trout through the spring and early summer. “Put-and-take” trout
stockings are necessary to provide a trout fishery.
Class 4. Rating of 6 or less A stream which will not support trout throughout much of the year. Such streams should either not
be stocked or be stocked as a warmwater stream. Streams in this category should be reviewed closely
before trout are stocked
