an Outreach Program To Create a Fish Friendly Lake Washington
UW graduate student team intends to complete three overlapping and interwoven
1) Lake Washington property owner interviews to identify barriers and
incentives to adopt fish friendly shoreline modifications
of Lake Washington shoreline (using GIS and other tools)
characterization of shoreline regulatory framework including existing barriers
and incentive programs.
What is a 'fish friendly' shoreline?
A fish friendly shoreline is one where the
ecological function of the shoreline is conducive to salmon rearing and
migratory behaviors. Several species of salmon including the Sockeye and
the endangered Chinook use Lake Washington at different stages of their
life. In order to improve the Chinooks chances of re-establishing a
stable population, several steps must be taken; one of these steps is to
improve the Chinook's spawning environment. Although many local rivers
where Chinooks spawn have been improved, the state of their migratory pathways
through the lake system is still far below optimal. By modifying
shorelines, it is possible to improve the conditions for these salmon while
still maintaining a landscape that does not preclude the joys (boating, swimming,
dock fishing, etc) of water front property ownership. The following two
sketches elegantly display the differences between traditional shoreline
armoring and fish friendly shoreline construction.
The first home employee's a traditional sea wall which is deleterious to young salmon fry.
This second home employee's a fish friendly design which allows for safe passage for young salmon while still creating a beautiful landscape and an enjoyable recreation site.
