Wyoming wants to modify the Fontenelle Dam so it can use an extra 80,000 acre-feet of water from a tributary of the once-mighty Colorado River. At its headwaters, Denver Water hopes to expand a reservoir’s capacity by 77,000 acre-feet of water. And several hundred miles south, Utah is trying to build a pipeline that can funnel another 86,000 acre-feet out of the river.

Exploring the Hydrodynamics of Sediment Diversion at Mid-Barataria

graphics: The Mississippi River typically has one to four high-water peaks between November and June.

This is part two of the series “Building Land in Coastal Louisiana: Expert Recommendations for Operating a Successful Sediment Diversion that Balances Ecosystem and Community Needs.” Please follow the link below for the original(s).

Historically, the Mississippi River has periodically overtopped its natural levee and flooded the adjacent wetlands with sediment-laden water. This natural process has been interrupted by the construction of flood control levees, and the available sediment has … [more…]

Mississippi River Sediment Diversions

Overview — Sediment Diversions

The impacts of coastal land loss threaten Louisiana’s economy, commerce, infrastructure, and culture. Furthermore, the collapse of coastal Louisiana would negatively impact the entire country – we provide protection for infrastructure that supplies 90% of the nation’s outer continental oil and gas, 20% of the nation’s annual waterborne commerce, 26% (by weight) of the continental U.S. commercial fisheries landings, and winter habitat for five million migratory … [more…]

Will Diversions Introduce Nutrients That Harm Wetland Vegetation?

Will Diversions Introduce Nutrients That Harm Wetland Vegetation?

Aerial picture of the Caernarvon Freshwater Diversion outfall canal (on the right) and the delta built by the diversion in Big Mar Pond. The photo was taken on July 17, 2014. Note the lush, green vegetation on the newly built delta includes wetland grasses and black willow trees. All of these plants colonized on their own, once the diversion built the land.

Within the scientific community, and among the general … [more…]
