Puget Sound Stream Benthos
Status & Trends Project, City of Seattle
Seattle Public Utilities collects benthic macroinvertebrate samples from several creeks within the City of Seattle limits. The data from these sites are analyzed for two main purposes. First, to evaluate the short-term biological impact of various creek and watershed restoration activities. Second, to track status and trends for the long-term biological health of the creeks. For more information, please contact Katherine Lynch at Katherine.Lynch@seattle.gov, (206)233-5194.
