This update is intended to provide preliminary results from work conducted during 2007 regarding migratory bull trout life history, abundance, distribution, and habitat conditions in the Walla Walla Basin, and to provide insight into the effect of physical and hydrologic conditions on bull trout biology and connectivity between local populations and core areas. Work conducted in 2007 will be reported on in more detail in our 2007 Annual Progress Report later this spring.
