A Flood of Hope - California WaterBlog By Ted Sommer . . . My most inspiring bike ride this past year was not on a mountain or in some exotic destination. It was sixteen flat and muddy valley miles under overcast skies. My destination was ...

Great blog post from Ted Sommer on a quarter century of science and dedication to turn good ideas into reality, increasing access for native fish to the super-productive habitats on floodplains.

#WaterYear

Today is #WorldWildlifeDay - a good time to celebrate that wildlife also includes swimmers, e.g., Irrawaddy Dolphin, from Mekong (Laos) in 2013 (dolphins now gone from Laos).

Rivers are also essential for wildlife that walks, for habitat & corridors (elephants along Zambezi)

The US Had a Big Battery Boom Last Year Despite Donald Trump’s unrelenting attacks on renewable energy, there’s a quiet revolution happening on US grids.

Big Battery Energy? Yes, America boomed in 2025. πŸ”‹ Batteries are one of the 6 technologies outlined by Sr. Scientist Amanda Smith, PhD. that will make up the cleaner electric grid of the future.

On this day in 1968, Ohio became perhaps world’s first gov't to legislate system of protected rivers: Ohio Wild and Scenic Rivers Act preceded U.S. Wild & Scenic by 10 months. Little Miami River was first

Grand River was the second protected river

β€ͺTell me the truth...I'm ready.

New IPBES report finds that $220 billion were directed to conservation & restoration of biodiversity in 2023...

yet $7.3 trillion flowed toward subsidies that directly harm nature.

Final EIA-860 is out, and 2025 really did it: 54 GW of new U.S. electric capacity, 96% clean. Solar again carries the offense, and we built more storage in 2025 than the cumulative total through 2023. More and more and more additions... but also record low retirements.

For Valentine’s Day, A Rom-Com For Nature-Based Solutions Proponents of Nature-based Solutions need to make the case NbS can be effective at large scales. For this, there may be no better demonstration than the Yolo Bypass in California's Central Valley.

Proponents of #NatureBasedSolutions need to make the case that #NbS can be effective at large scales. For that, there may be no better example than the Yolo Bypass (CA). As it's almost Valentine's Day, I make that case with the language of rom-coms. #floodplain

Improving How We Track Progress For River Protection Rivers have relatively less protection than do land or oceans and we lack effective mechanisms for measuring protection. A new study offers an improved mechanism for tracking progress.

River need greater protection, but to date our methods for tracking protection status have been limited. In this post I describe a new method from @oldenfish.bsky.social @americanrivers.bsky.social and Conservation Science Partners - the Protected River Index

Record heat is the new normal, says WWF's @stephanieroe.bsky.social, as 2025 ranks among the three hottest years ever. The good news? Climate solutions are breaking records too. Rapid emissions cuts are possible. More here: t.co/Ph4h3mU6i8
