In 2005, the Yakama Nation launched a restoration effort in Hancock
Springs, a tributary of the Methow River. Though there is no
documentation of salmon and steelhead historically using the
tributary, unique ecological conditions associated with the creek, such
as a consistent hydrograph and favorable year-round temperatures,
imply that Hancock Springs was a major natural production site for
salmon and steelhead. Today, the federally listed fish have returned to
Hancock Springs.
