Dry year myths revisited

Todd Manley writes, “It might be hard to imagine that it has already been more than five years since we exited the extreme dry years of 2014 and 2015. At that time, local, state and federal water managers were taking unprecedented actions in response to the dry conditions to maximize beneficial uses and every Californian was feeling the impact of multiple dry years. A crisis such as this creates an environment in which different viewpoints are easily developed and rapidly disseminated, sometimes without supporting information or facts. In response to four of the more prevalent myths we heard during this time, NCWA posted a blog in April 2015 to help dispel the myths and direct our collective attention on empirical data, facts, and constructive actions to address dry year conditions. … ”  Read more from the Northern California Water Association blog here: Dry year myths revisited

A swiss cheese model for fish conservation

Here’s some food for thought: Nicholas Chistaki’s “Swiss Cheese Model for Combatting Covid-19” layered approach can be applied to other problems, ranging from drinking water quality to fish conservation.  “Christakis presents a model for considering the individual steps needed to achieve a larger goal, and how each step should fit into a larger strategy. He points out that each action used to limit the spread of Covid (handwashing, mask wearing, social distancing) creates a layer of imperfect defense akin to a slice of Swiss cheese. No action alone is 100% effective – there are holes.” ... ”  Continue reading at Cal Trout here: A swiss cheese model for fish conservation

Sacramento River salmon redd dewatering in fall 2020

Tom Cannon writes, “The Bureau of Reclamation’s standard fall operation of Shasta Reservoir and Keswick Reservoir dewaters the redds of fall-run Chinook salmon in the upper Sacramento River near Redding.  The peak in fall-run Chinook salmon spawning is October-November.  Eggs and alevin (hatched sac fry) remain buried one to two feet down in the gravel spawning bed (redd) for about three months.  As I described in a November 2019 post and in prior posts, drops in flow and associated water levels cause varying degrees of redd stranding or dewatering, and the affected eggs and alevins die. … ”  Continue reading at the California Fisheries blog here: Sacramento River salmon redd dewatering in fall 2020

Local water management unified through ACWA

Steve Lamar and Pamela Tobin write, “At the heart of ACWA’s success is the fundamental commitment to working together as a vast and diverse membership of local water agencies to find creative solutions to the challenges of the day.  It is a dominant theme of the association’s value statement (“collaboration,” “mutual respect,” and “solution-oriented”) and is part of our organizational DNA. While the New Year already poses formidable challenges for California’s water community, ACWA’s commitment to roll-up our sleeves together to build from the combined experience and expertise of our membership will serve us well yet again. … ”  Read more from ACWA’s Voices on Water blog here:  Local water management unified through ACWA

How to Save the Colorado River and Other Tales

Michael Campana writes, “I just saw a copy of the November 2020 issue of the magazine Rocky Mountain Water, which is published by the Rocky Mountain Section of the AWWA and Rocky Mountain Water Environment Association. The issue has articles Impacts of Wildfires on Water Quality and Water Treatment (page 16) and How to Save the Colorado River (p. 25). … ”  Read more from the Water Wired blog here: How to Save the Colorado River and Other Tales 

EPA must protect vulnerable groups from water contamination

Aaron Colangelo writes, “Twenty-five years ago, Congress directed the Environmental Protection Agency to research the health risks that contaminated drinking water poses to vulnerable groups of people, including infants, children, pregnant women, and the elderly. Congress instructed EPA to undertake an ongoing research program to study these risks and report back on the results periodically. EPA started this research and sent an initial report to Congress in December 2000. In that report, EPA summarized the wide range of studies it had initiated, much of which was just getting underway. And EPA reported that “new insights are expected within the next few years,” as the results of ongoing work become available.  … ”  Read more from the NRDC here: EPA must protect vulnerable groups from water contamination
