The Eel River Recovery Project (ERRP) is a broad-based community initiative to address water conservation, nutrient pollution and ecosystem recovery. This project is operating under the umbrella of the Trees Foundation and Institute for Fisheries Resources and has an Advisory Group comprised of people from throughout the Eel River Basin. The collaborative effort to restore the Eel River is coordinated with communities, Tribes, other non-profit groups, and government agencies.


Yellow Legged Frog Survey

On Saturday, April 18, several ERRP volunteers counted Yellow-Legged frog egg masses in the South Fork Eel near Benbow to help determine abundance. Read the short report in Power Point.

In April, ERRP volunteers took researcher Sarah Kupferberg in a kayak to survey the river from just below Meyers Flat to above Weott. See photos on Loleta Eric's Facebook.

Cyanobacteria and Cyanotoxins in the
Eel River, 2013 – 2014

Summary of Report Findings

  • From June – September, 2013 and 2014, sites along the South Fork Eel,
    Main-stem Eel, and Van Duzen Rivers were monitored for cyanobacterial
    mats and cyanotoxins.

 

  • The common cyanotoxin producing cyanobacteria in the Eel are species of Anabaena and Phormidium, but Nostoc also produced cyanotoxins.

 

  • Anabaena grows in slower flowing water, often on top of other types of nontoxic algae. Phormidium grows on rocks in fast-flowing riffles and rapids.

 

  • Of the two cyanotoxins monitored, the neurotoxin, anatoxin-a, was detected at higher levels in the Eel than the liver toxin, microcystin.

 

  • Cyanotoxin concentrations were highest in the middle reaches of the South Fork Eel between Meyers Flat and Leggett.

 

  • Cyanotoxin concentrations peak in late July and early August, but local hotspots may still be present through September.
