El Dorado Trout Unlimited has wrapped up its monitoring program for the year and has begun the process of data analysis that will culminate in a watershed assessment. Thanks so much to our amazing monitors and volunteers! Thanks also to Trout Unlimited for an Embrace a Stream grant that helped to fund this important work!
Meanwhile, the Chinook salmon run has begun, the earliest connection since passage barriers were removed. Keep your fingers crossed for more rain, so this large run won't be stranded due to continuing diversions & overdraft....
El Dorado TU's Cosumnes River Monitoring Program continues!
The monitors have done a great job--and have now embarked on the CDFW habitat analysis for each site, with seven sites evaluated so far. The August upper watershed is looking good, but the Valley area of groundwater overdraft is dry. Let's hope it re-connects in time for the salmon run!

Thanks to our Citizen Scientist monitors for a successful June monitoring event! It's nice to see conditions with a bit of snow pack behind it: temperatures were on average 3-4 degrees lower across the watershed then June 2015. Flows were also stronger:
Flow at North Fork, June 2015: 7.6 cfs Flow at North Fork, June 2016: 17 cfs
Flow at Middle Fork, June 2015: 43 cfs Flow at Middle Fork, June 2016: 110 cfs (inaccurate due to new swimming dam? Note the total flow at the mainstem)
Flow at Mainstem, June 2015: 18 cfs Flow at Mainstem, June 2016: 62 cfs
But the big news for this monitoring event has to be the presence of fish.
El Dorado Trout Unlimited (EDTU) is continuing its Citizen Scientist Monitoring Program for the Cosumnes River in 2016. We monitor key parameters of the river and take structured observations of habitat and species present. Information gathered is part of a watershed assessment, in preparation for restoration work. EDTU is working with partners American River Conservancy, Cosumnes Culture and WaterWays, Fishery Foundation, and Landmark Environmental Consultants to create innovative, win/win solutions that support communities and river health. And good river health leads to good fishing!
April is "Get Ready Month"!
As April days unfold, signs of spring are arriving. Green grass, wildflowers, water quality monitors thinking of their sites by the river...AT EDTU, we're getting ready for monitoring season.
Angler Science: How our angler members contribute to the science behind TU conservation.
Melinda Frost-Hurzel is leading a project in our chapter monitoring the Cosumnes River.
Check out the following opportunities for anglers to contribute to the scientific understanding of trout and salmon conservation.
The El Dorado Board has selected a Monofilament Collection Bin as its first conservation project. The bin would be assembled in large numbers for installation throughout the county. The bins would be placed at convenient stream side locations where fishing traffic would pass. Locations would include boat ramps, trail heads or other fishery gathering spots. Ron Zigelhofer, our president, has assembled a prototype as seen in the images. We will analyze and refine the design and then built units for installation. A project team will be assembled to critique the design, estimate the number of units to be installed, procure materials, build units, gain approval for installation, procure stickers and accomplish installation. Sign-up on the home page if you can contribute to this project.
