At the same time, the ratio of storage capacity/mean annual water yield for dams is greatest for Interior Western, Ozark/Ouachita and Great Plains rivers and least for Pacific Northwest streams. Thus, in many cases those rivers with the highest annual variability have the greatest potential ...
Part 01 Intro For six million years the Colorado River and its dozens of spectacular tributaries carved out the Grand Canyon and scoured the Rockies, flushing mineral-rich sediment to the sea. These rivers weren't always in flood, but they never ran dry. Today, however, the second largest ...
Ensuring Healthy Water Flows– Scientists are developing new models to establishminimum flow requirements for the Scott and Shasta Rivers, setting a precedent for similar protections across the state. Innovative Salmon Tracking– The implementation ofParental-Based TaggingusesDNA technologyto more accurately...
and steep escarpments give way to a basin and range system. River valleys here support clusters of cottonwood, willow,mesquite, and sycamore trees, and mule deer, fish, and waterfowl. The areas away from the rivers are characterized by desert flora and fauna, including mesquite, creosote bush...
rivers. Here we used a community science effort to accelerate the sampling, sequencing and genome-resolved analyses of river microbiomes to create the Genome Resolved Open Watersheds database (GROWdb). GROWdb profiles the identity, distribution, function and expression of microbial genomes across ...
The South Fork of the American River is the premier rafting river in California and one of the most popular rivers in the United States. Located in the heart of the Sierra Foothills smack in the middle of Gold Rush Country, the South Fork of the American is a great way for families, fr...
Wild salmon returns plummeted by over 90 percent following the construction of four federal dams - Ice Harbor, Lower Monumental, Little Goose and Lower Granite - on the lower Snake River in eastern Washington state. Today, thirteen salmon and steelhead runs in the Columbia and Snake rivers are ...
Many of these rivers and/or their tributaries have been impounded for hydropower generation, flood control, irrigation, potable water supply, navi- gation and recreation, leading to fragmented river networks and regulated flows4,6. Indeed, numerous dams have been built across the USA and Canada ...

Throughout this study, we identified low abundances of river dolphins compared to other Amazon rivers. Boto may not be sustainable at a population level, due primarily to population fragmentation which would result from the construc- tion of the proposed dams. Precautionary measures are urgently ...
