Laguna de Santa Rosa - Santa Rosa to Sebastopol, CA

The two citizen monitors in the Laguna are Steve Green and Gail Ohlander.

From Steve: Hi…. I'm Steve, and I'd first like to comment that Sebastopol is a wonderful town for myself, my wife and my two teenagers. We all feel very lucky to live here and enjoy having the best of northern California at our doorstep. My kids attend Analy high and for the last five years we have been participants in the downtown parade (in one group or another).
We live south of town near Hillcrest school, off Bloomfield road, and my kids and I volunteer our time to the CCWI cause.
When we do this work on the weekends… We get feedback from folks as they walk the trail. They ask me… what am I doing? When I tell them they say, " Thanks, keep up the great work"! Some even want information so they can add their support, too.
A couple of times I got this question, " is it safe to let my dog drink here"?
I hold up my sample bottle of semi-brown water and say "it may look bad, but for a dog it probably taste a lot better than the water in your toilet bowl".
What will I tell them after it rains and the runoff from the streets, Santa Rosa sewage plant and dairy farms has fouled the water? The Laguna at Sebastopol is a great place to experience how human activities affects the water we all depend on for our survival. The Laguna de Santa Rosa is an eco-system that provides information about how two large communities (Santa Rosa and Sebastopol) are affecting our local environment and the ground water we draw from wells.

From Gail: Occupational and environmental health is, and has been, a personal and professional interest. As a retired Occupational Health Nurse I was looking for community volunteer opportunities that meshed with my areas of interests, so I was delighted to identify the CCWI group. I have been with CCWI for about two years and consider it a bonus that water monitoring is an outside activity that is done in the California sunshine. My four water monitoring areas are near Sebastopol, so if you are interested in seeing what CCWI does please contact CCWI @ 707-824-4370 and join me for a field experience.

Laguna de Santa Rosa Monitoring Plan

Objectives: The focus of this project is to identify pollution sources and problems in water quality, and use data collected to develop fact sheets and educational materials for the general public highlighting best management practices and strategies for reducing pollution. The Laguna de Santa Rosa is a salmonid stream that has been urbanized. Of particular concern is the Sewage Disposal plant in this urban watershed which discharges treated wastewater into the Laguna, resulting in high nutrient levels. Colgan Creek is a tributary to the Laguna de Santa Rosa, and is the closest waterway to the Regional Wastewater Treatment Plant.

Data Collection Activities:
Dissolved Oxygen (DO)
Conductivity (Ions)

When: The project's initial sampling dates for specific sites are:
LAG040: June 20th, 2003
LAG030: January 23, 2003
LAG050: February 18, 2005
LAG080: April 20, 2005
COL020: June 20th, 2003

Why: Parameters were chosen according to general interest to citizen monitors, and relation to erosion impacts. Sites were chosen according to the following criteria:
- Representative of the areas of the Creek for general creek characterization.
- Concerns of water pollution resulting from urban runoff.
- Concerns with flow interference and morphological disturbance due to channelization.
- Safety during high flows.

How: The monitoring program is intended to develop baseline characterization data, document water and habitat quality changes over time and to help establish a scientific basis for land use decisions. Sites and parameters were chosen after discussions with local residents.
Citizen Monitors:
LAG030- Steve Greek
LAG040- Gail Ohlander
LAG050- Gail Ohlander
LAG080- Gail Ohlander
COL020- Gail Ohlander

The information and data developed will be shared & coordinated with the Laguna Foundation, Sebastopol City Council, State Fish & Game, Federal Fish & Wildlife, County Board of Supervisors and the Planning & Resource Management Department. Quality Control measures will be incorporated in the plan so that the data will be credible.
