WCT Multi-state Assessment 



February 10, 2003 



Table 14. Land-use and fishery management activities having potential to impact a conservation population. 



The population assessment will address source/sink relationships that may exist between headwater WCT 

 conservation populations and those conservation populations lower in a drainage, especially where barriers to 

 upstream movement might exist. While headwater WCT populations may include those isolated by impassible 

 barriers to upstream fish movement (and thus could not be re-founded or receive external genetic material 

 without human intervention), these headwater populations may be important sources for re-founding and 

 augmenting lower populations. This will be handled by a simple identifier check indicating that a given 

 population operates as a source. Any downstream population would then automatically become a "sink" 

 recipient.
