The project treatments
for the Entiat Habitat Improvements project envisions the placement of
approximately 5 cross vanes in the lower Entiat River reaches 2-9, and
the installation of approximately 5 log retention structures in the
upper middle Entiat. The cross vane installation in the lower Entiat is
intended to increase the amount of pool habitat, increase large woody
debris (LWD) loading, reduce channel confinement, and restore a measure
of riparian function. The log structures in the upper middle Entiat is
intended to increase LWD density, backwater pools, high flow refuge
habitat and tail out habitat and habitat diversity. These measures are
consistent with the Entiat WRIA 46 Management Plan diagnoses for Entiat
