Sierra Club EPEC Program

Verde River Water Sentinels--Your Opportunity to Help Protect the Verde River!

Mark your calendars for these Water Sentinels activities:

  • Our next monitoring date is Saturday, December 20, 2008. Checking flows and water quality monitoring on the Upper Verde River will be our tasks for the day.

    We hope you'll join us!

    For more information on the monitoring project and upcoming monitoring and clean-up activities, please contact the Grand Canyon Chapter office at (602) 253-8633 or

    Volunteer Bruce Thompson dons waders to take water samples at Beasley Flat on the Verde River.
    For more than a year the Sierra Club's Grand Canyon Chapter has been heading out to the Verde River every other month to collect water samples and flow data at seven locations along the upper portion of the Verde River. The Upper Verde Water Sentinels sample for E. coli, arsenic, nitrogen, and phosphorous. Three groups - a group from the Prescott area, a group from the Verde Valley, and a group from the Phoenix area - gather the samples and then the Phoenix group runs them down the hill to a Phoenix lab for analysis. Two other groups also measure flows on the river and the Sierra Club is currently working on a program to measure sediments.

    Wet feet? No problem! Volunteer JD Trebec wades ankle-deep into the water monitoring project on the Verde River.
    The Verde River, nominated by the Sierra Club and designated by American Rivers as one of the ten most endangered rivers in the country in 2006, faces significant threats. The river is severely threatened by excessive groundwater pumping to feed development and several pipeline projects proposed by the communities of Prescott, Prescott Valley, and Chino Valley, plus a myriad of water quality concerns including application of sludge to the land nearby. Our Upper Verde Water Sentinels welcome additional volunteers to help protect this amazing river which provides important habitat for fish and wildlife, drinking water, as well as great recreational opportunities. The hope and expectation is that the knowledge and experience gained through this project will help people act to protect the Verde and other rivers in the state.

    To make this program successful, we need volunteers who are willing to commit to attend one training session, at least three monitoring activities, and to assist with at least one streamside clean up. This project will provide a great opportunity to get your hands dirty and feet wet. Volunteers will measure stream flow and collect water samples for lab testing. Please join us in this fun and meaningful project! Our next monitoring date is Saturday, December 20, 2008.

    For more information on the monitoring project and future monitoring and clean up activities, please contact the Grand Canyon Chapter office at (602) 253-8633 or
