Salmon lose diversity in managed rivers, reducing resilience to environmental change

December 5, 2019
From the National Oceanic and Atmospheric Administration (NOAA)

The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.

The good news is that even small steps to improve their access to habitat and restore natural flows could boost their survival.

SMUD Roseville Water Transfer comments

On September 10, 2019, the Environmental Council of Sacramento and Habitat 2020 sent a letter to Sacramento Metropolitan Utilities District (SMUD) a letter regarding a proposed water transfer between the City of Roseville and SMUD. Below are some excerpts from the letter, followed by a link to the letter in full.

Recently the Environmental Council of Sacramento and Habitat 2020 became aware of the pending temporary water transfer between the City of Roseville and SMUD. Our review of the environmental assessment and decision document prepared by the Bureau of Reclamation found specific deficiencies in the analysis and a casual dismissal of the transfer’s cumulative significance. We believe that the proposed transfer of water does not contain the necessary safeguards to protect Lower American River fisheries. We request that the SMUD Board direct its staff to include provisions in the contract that will address these concerns.

We believe the transfers must be governed by the standards and requirements contained in the Modified Flow Management Standard. These standards and requirements would much better ensure that the transfer would not negatively impact the American River flow and temperature standards.

Editor’s note: A bridge to somewhere

Sacramento News and Review

The I Street Bridge is 108 years old and rusty, and it rattles when a train passes over it. So, yes, a new span over the Sacramento River is way overdue. But the new bridge is not just another important transportation link between Sacramento and West Sacramento. It’s also an opportunity to make a design statement for the region.

The current I Street Bridge will stay open. The lower deck will continue to be used for passenger and freight trains, while the upper deck will be closed to vehicles and be converted into a pedestrian and bike path. The new bridge is just up river and will connect Railyards Boulevard on the edge of downtown Sacramento, and C Street in the Washington neighborhood in West Sacramento.
