Glossary
anadromous Those species of fish, such as salmon, that hatch and typically rear in freshwater, migrate to the ocean to mature into adults, and return upstream to freshwater rivers, streams, and lakes to spawn.
basin The land area whose run-off drains to a to a stream, lake, or ocean. As applied in this report, used to refer to subbasins within the Lake Washington Watershed.
escapement Estimated number of adult salmon returning to a stream to spawn.
kokanee Non-anadromous sockeye (Oncorhynchus nerka); lives its entire life in a freshwater lake, then returns to its native stream to spawn.
natal Pertaining to the place of birth; a natal stream refers to the stream where a juvenile salmon was hatched.
redd A nest of fish eggs in the gravel of a stream or river bed. Spawning salmon dig a depression in the gravel by lying on their sides and hitting the gravel with their sides and tail, pumping the water to move the stones. After the female deposits eggs into the depression, the male salmon fertilizes them, then the female digs another depression just upstream to cover the eggs. The pair may do this three or four times. New redds usually look like mounds of light-colored gravel with a slight depression in the gravel just upstream of the mound.
river mile Statute mile as measured along the center line of a river; river miles are measured from the mouth in an upstream direction (e.g., RM 1.3), but can also be used as a discrete measure of distance in a river or stream (e.g., 1-3 river miles).
salmonid Fish species belonging to the Salmonidae family, which includes salmon, trout, char, and whitefish.
watershed The land area whose run-off drains to a to a stream, lake, or ocean. As applied in this report, used to refer to the Lake Washington Watershed: all waters draining through the Ballard Locks.
