Eel River • 3rd largest river system in the state of California. • What are the other two?
Eel River : 2nd most sedimented river in the world next to the Yantze River in China
Van Duzen River The Coastal Range in the Van Duzen River Basin is the most erosive of its size anywhere in the United States.
What causes this sedimentation. • Natural : very erosive Franciscan Melange: Read from Dave Heaton • Humans: Timber Harvesting, Roads, etc. • 2 particles to 1 particle • Natural to Manmade Causes
Is this acceptable? Tremendous impact on the the fisheries, and the amphibians. Latest EcoNews
In 2004, CDF approved 5000 acres of timber harvest on 21% of Palco’s holdings in the Van Duzen These lands were harvested over a 3 year period and completed in 2007. Watershed Shedding
Changes in the HCP • 2004 PALCO received permission to harvest timber only 50 feet from the Channel Migration Zone effecting bigger trees, canopy, salmon habitat, and increasing the levels of sediment delivery to all tributaries of the Van Duzen River.
It could always be worse! • In February of 2008, the Yantze River began bubbling red endangering the water supply for over 200,000 people. • TRUE or FALSE
Description • In Sept.2006, Van Duzen Project was approved by the California Water Quality Control Board to conduct a two year study of water quality in the Van Duzen River Basin • We are now completing our 2nd year of the project with an extension to write a Watershed Plan • Make recommendations for the reduction of sediment into the Van Duzen River Basin – TMDL FOR MORE INFO.. www.fovd.org.
Citizens Monitoring Group • Tremendous volunteer group • We are presently monitoring Rainbow Bridge, Grizzly Creek, Hely Creek, Flanigan Creek, Fox Creek, Upper and lower Cummings Creek, Wilson Creek, Yager Creek, Wolverton Creek, and the Main Stem of the Van Duzen River.
