2. Definition of a Coldwater Stream
Streams where game fish populations are predominantly salmonids.
Streams that maintain salmonid populations by sustaining spawning and rearing of juveniles rather than just serving as migratory pathways (self-sustaining population requirement).

4. Classification Salmonid Populations
Anadromous species that move out of streams and to the sea or lakes immediately after emergence (chum and sockeye salmon).
Anadromous species that spend 1-4 years in natal streams before moving to sea (Atlantic Salmon, Steelhead).
Resident species that spend their entire lives in streams (Cutthroat Trout, Brook Trout).

5. Classification Salmonid Populations
Anadromous vs. Stream Resident
Mobile vs. Sedentary

13. Classification of Coldwater Streams
Freestone: Water mostly is delivered overland or through shallow groundwater; highly variable stream flows; most of WV.
Spring Creek: Deep ground water dominated streams, generally in karst geology; relatively stable flow, temperature, and water chemistry.
Tailwater: Cold water comes from hypolimnetic release from an upstream dam, highly regulated flows systems (some can be stable flow, others highly variable).

Freestone stream: Joes Run, WV
Spring creek: Timber Coulee, WI
Tailwater river: White River, AR
