2011 Mermaidfest a success!

We hope you enjoyed the food and music and fun as much as we did. The money raised is an important part of the work done by all who volunteer here at CCWI. Thanks to all who joined us at Mermaidfest 2011 in Rio Nido. And thanks most of all to Vira the California Mermaid who made it all possible.

Dutch Bill Creek Water Quality Study 2009

The primary objective of CCWI’s Dutch Bill Creek Water Quality, Turbidity, Nutrients and Bacteria Study was to collect water samples on Dutch Bill Creek over the 2007/2008 and the 2008/2009 winters in order to document and analyze the water quality of Dutch Bill Creek during storm events. A secondary objective was to train interns and interested citizens in the study and to present the information to the public. To see the full report click here.

Here's a map showing Surface Water Temperature for many of our monitoring sites during June 2009. Here's a map for May 2009. Yes, high temperature is considered a pollutant, since salmonids require cold waters to survive and thrive. Optimum temperature for rearing coho salmonids is generally between 10° C and 16° [C Welsh et.al. (2001); Hines and Ambrose (1998)].
