FISHERY SURVEY - NUMBER OF Juvenile Fish from 2010-11-01 to 2011-03-01 (NCEI Accession 0148761)

Over the past few years biologists and other researchers have encountered noticeable fish die-offs, mostly of young salmonid, in various stretches of Little Campbell Creek. The USFWS prepared a summary report of these events titled Frequency and Distribution of Fish Kills in Little Campbell Creek, July - September 2005. One of the most obvious reasons for the fish die-offs is degraded water quality including an increase in turbidity, and there are many reasons for this. Turbidity data was collected and reported in Turbidity Monitoring in Little Campbell Creek, Summer 2005. Some of the most obvious are inputs from the city’s storm water system, stream channelization and its effects, removal of wetland filtering areas, and the impacts of urbanization (building of roads, construction, vegetation removal, increases in impermeable surfaces and the associated run-off of chemicals from various sources, and channeled run-off of storm water into the creek). Another USFWS report, Restoring ecological function and value to aquatic resources in the Little Campbell Creek watershed: Recommendations for the Great Land Trust summarizes the problems and some potential solutions.
