Audio: Proposed federal water bill would streamline new dam projects | 89.3 KPCC

The bill would codify into federal law the 1994 Bay Delta Accord, an agreement between state and federal authorities to coordinate water use and quality standards for water in the California Delta, where the confluence of the Sacramento and San Joaquin rivers enters Suisun Bay and flows toward the Pacific Ocean. Making the accord a federal law would restore water deliveries to Central California users that were “cut off by environmental lawsuits and a series of illogical regulations,” Valadao says in the bill’s summary.”

Stream lining dam project process good for farmers but what about the environment?

Exeter’s Great Dam Removal :: NOAA Fisheries

https://www.greateratlantic.fisheries.noaa.gov/stories/2016/september/08_exeter_s_great_dam_removal.html

Good news for boaters! And everyone!

Friday, September 9, the town of Exeter, New Hampshire celebrates the removal of the Great Dam and the restoration of the Exeter River. The town will hold a public ceremony in Founders Park at 10am.

There have been dams along the Exeter River since the 1640s or so. The Great Dam, named for the nearby Great Falls, was built around 1831 to provide power to Exeter’s mills. After coal and oil power came to Exeter, the Great Dam continued to provide power to Exeter businesses into the mid-20th century. When the dam’s owner sold the dam and factories in 1981, the Great Dam was donated to the Town of Exeter.

With the need for the dam gone, the Great Dam fell into disrepair. In 2000, the New Hampshire Department of Environmental Services advised the town that the dam had serious safety and flooding issues. The Town considered repairing, modifying, or removing the dam, and finally decided that removing the dam was the best solution.

Dams produce more greenhouse gas emissions than we thought — Quartz

http://qz.com/797380/reservoirs-methane-emissions-climate-change/

Katherine Ellen Foley on the problem with “clean” hydropower. “Globally, the reservoirs created by dams may actually contribute almost a gigaton of carbon dioxide-equivalent emissions—about 25% more than they had previously thought. This means that we’ve almost certainly been underestimating how much greenhouse gas we’ve been shooting into the atmosphere.”

Another reason to let rivers run their natural course….too late to stop China’s 3 River Dam on Yangtze.

The Southern Ocean is getting less salty. Here’s what that could mean for the rest of the world – The Washington Post

https://www.washingtonpost.com/news/energy-environment/wp/2016/08/31/how-sea-ice-is-making-the-southern-ocean-less-salty-and-what-that-might-mean-for-the-rest-of-the-world/?utm_term=.508241e0b68d

Saltinity important to ocean processes: 

These processes are important drivers of ocean currents all over the world. The salty water created by sea ice formation is denser than fresh water, so it has a tendency to sink to the bottom of the ocean. In doing so, it helps push the water below it forward along the sea floor, creating a current that runs north toward the equator. As the water warms up, it rises to the surface and eventually runs back toward the poles. This process helps carry heat and nutrients around the world.”
