Topic Aquatic Invertebrates: Walker Creek EPT Taxa 2001
 
Caption:  This graph shows average EPT Taxa for sites in the Walker Creek watershed sampled in spring 2001. Data were collected by the San Francisco Bay Regional Water Quality Control Board. The reference value shown in the graph provides a regional comparison to preliminary scoring criteria developed by the California Department of Fish and Game for the Russian River Index of Biological Integrity using California Stream Bioassessment Procedure for first to third order streams (Harrington et al., 1999). This study found that EPT Taxa less than 12 reflected highly impaired conditions. See Info Links for more information.
