Final Supplemental EIS
Level of service: A measure of the quality of traffic flow based on speed and travel time,
freedom to maneuver, and traffic interruptions. Level of service (LOS) is rated from A to F, with
A being the best (free-flow) conditions and F being the worst.
Limnetic: Pertaining to or inhabiting fresh water.
Littoral: Pertaining to or existing on or near shore.
Mode: A particular variety or form. In this EIS, usually a particular form of transportation such
as automobile, bus, carpool or bicycle.
Natal: Pertains to the birthplace of an organism.
Ocean-type: Refers to a Chinook salmon that migrates from its natal stream to the ocean as a
sub-yearling (age 0 fish).
Off-Peak: Any time during the day outside the peak travel period, typically when traffic flows
are not constrained by roadway or facility capacity.
Outmigrant: An outmigrant is a salmonid smolt that migrates from the stream where it was
spawned to the ocean (the migration can also be to a larger stream or lake).
Peak Direction: Direction of maximum traffic flow during the peak hour. For example, this
may be westbound during the AM peak hour and eastbound during the PM peak hour.
Peak Hour: The hours within the day during which the maximum volume of traffic passes a
defined roadway point: one hour in the morning (AM) and one hour in the afternoon (PM). The
peak hour typically correlates to “rush hour.”
Peak Period: A time period during which the maximum volume of traffic passes a defined
roadway point. In the DEIS, both three-hour and six-hour periods are considered.
Phenotype: The outward physical manifestation or physical characteristics of an individual or
an average individual from a population of organisms.
Queuing: In the context of traffic analysis, vehicles lined up awaiting a turn or change of traffic
signal.
Recharge: The entry into the saturated zone (i.e., aquifers) from surface water infiltration.
Redd: A salmonid “nest” where eggs are buried in gravel. Redds appear as clean depressions in
stream gravel during spawning surveys.
Resident Rainbow Trout: Refers to a rainbow trout that never leaves freshwater.
Residual: An individual in a population that is characteristically sea-run that never goes to sea
(“residualized”). “Residuals” are typically precocious males that mature earlier and at a smaller
size than anadromous individuals. Approximately four times more male juvenile steelhead
residualize than female juveniles.
