Summary

Purpose:

To identify areas with suitable water depths, water velocities, and
substrates for white sturgeon spawning habitat.


Abstract:

Estimates of spawning habitat for white sturgeons Acipenser
transmontanus in the tailraces of the four dams on the lower 470 km of
the Columbia River were obtained by ... using the Physical Habitat
Simulation System of the U.S. Fish and Wildlife Service's Instream
Flow Incremental Methodology to identify areas with suitable water
depths, water velocities, and substrates. Rearing habitat throughout
the lower Columbia River was assessed by using a geographic
information system to identify areas with suitable water depths and
substrates. The lowering of spring and summer river discharges from
hydropower system operation reduces the availability of spawning
habitat for white sturgeons. The four dam tailraces in the study area
differ in the amount and quality of spawning habitat available at
various discharges: the differences are due to channel morphology.
The three impoundments and the free-flowing Columbia River downstream
from Bonneville Dam provide extensive areas that are physically
suitable for rearing young-of-the-year and juvenile white sturgeons.


Geographic Description:

This study was conducted in the Columbia River from the mouth
(river kilometer 0) to McNary Dam (river km 470). The four dams

within the study area are operated primarily for hydroelectric power
generation and divide the river into three impoundments, Bonneville
Pool, The Dalles Pool, and John Day Pool, and a free-flowing river
reach. Bonneville Dam was closed in 1938, The Dalles Dam in 1957, John
Day Dam in 1967, and McNary Dam was closed in 1953. The four river
reaches differ in length, surface area, and other physical
characteristics.

Methodology:

Physical Habitat Simulation System (PHABSIM) used to evaluate
habitat available for spawning white sturgeons by determining the
relation between river discharge and spawning habitat downstream from
each dam within the study area. Determines the overall quality of
habitat of a particular unit of area of the river.
