"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"

State and federal agencies want fish ladder restored on Merced River

Two powerful state and federal agencies have stuck their toes, so to speak, into an ongoing lawsuit against Merced Irrigation District demanding the district reopen a long defunct fish ladder.

The California Department of Fish and Wildlife and National Marine Fisheries Service both sent letters to Merced Irrigation District after Water Audit California sued the […]

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!

In honor of tribal fishing rights, Washington State is replacing undersized culverts statewide to restore fish habitat.
This project at Chico Creek replaced a 36-inch pipe with a bridge, and realigned the stream bed to open up 21 miles of salmon-spawning habitat.
Chum salmon are already exploring a tributary that was blocked by a highway embankment.
