#GrandRapidsMI - Heavy equipment hits the #GrandRiver as historic #DamRemoval begins
Story by Brian McVicar, July 1, 2026
"Heavy equipment rolled into the Grand River Wednesday as crews installed a temporary barrier downstream of Gillett Bridge to catch sediment and debris, the first step in a long-planned effort to remove four aging low-head dams.
"The floating yellow barrier, known as a turbidity curtain, is designed to contain clouds of sediment stirred up during construction and prevent it from drifting downstream, said Mike Staal, river restoration project manager for the City of Grand Rapids.
" 'If there’s turbidity in the water, it impacts the aquatic habitat,' he said. 'So what we want to do is just minimize any of the impact, keep the sediment where it is.'
"The turbidity curtain is just the beginning of a carefully choreographed, two-year construction effort to remove four, century-old low-head dams along a half-mile stretch of the Grand River between Fulton Street and I-196. The result, officials say, will be a more natural waterway—safer for recreation, better for fish passage and more closely resembling the rapids that gave Grand Rapids its name."

#NOAA: $240 Million in #FishPassage Funding Recommended under #Biden's Bipartisan Infrastructure Law and Inflation Reduction Act
https://www.fisheries.noaa.gov/feature-story/noaa-recommends-240-million-fish-passage-funding-under-bipartisan-infrastructure-law #USpol #Conservation"46 projects will reopen migratory pathways, restore access to healthy habitat for #fish, and build #tribal capacity to develop fish passage projects... These projects will help recover endangered #MigratoryFish... In addition to projects led by #tribes, more than half of the remaining projects will directly involve tribes"

The #Oceans Are Missing Their #Rivers
For billions of years, rivers connected continents to the #sea. Then we came along.
By Erica Gies May 3, 2023
"In many places, the great culprit is the dam: a wall of concrete and stone bisecting a river, diverting its energy and water to human use. There are 58,000 'big dams'—50 feet high or taller—around the globe, with another 3,700 more planned, mostly in lower-income countries in Asia and South America.
"Many of the harms caused by dams are well-documented. They block fish passage and starve subsistence fishers; radically alter natural river regimes and aquatic creatures’ lifecycles; and flood forests, wetlands, villages, and historical sites. (They’re also less climate-friendly1 and reliable2 than is widely believed.) Now scientists are describing another impact that has received relatively little attention but appears to also be profound: Dams block #sediment-carrying river pulses into the ocean."

325 dams and weirs were removed in 16 European countries in 2022, with Spain, Sweden, and France leading the way. Removing dams and barriers improves fish passage and enhances aquatic habitat and water quality. Keep up the great work, dam busters!

Hey folks! Given my previous instance's explosive growth (yay!), but resulting bogging, I've been asked to migrate somewhere else in the #Fediverse. I've already chatted with a few of you here, so this may be a recycled #introduction. At any rate, I'm Ridge. I'm a PhD student at Clemson University researching small-bodied #FishPassage through culverts. I've enjoyed my first few days here on Mastodon, and am looking forward to your conversations on #fish, #scicomm, and beyond! Tight lines!
