A newly handed federal regulation emphasizes flood management alongside the Mississippi River—work that advocates imagine is vital because the river basin sees extra frequent and extreme excessive climate occasions because of local weather change.

The Water Assets Improvement Act (WRDA) is handed by Congress each two years. It provides authority to the U.S. Military Corps of Engineers to undertake initiatives and research to enhance the nation’s water sources. 

Signed into regulation Jan. 4, this yr’s package deal contains research on elevated flooding within the higher basin, flood mitigation measures all through the river system, ecological restoration and a $6 billion floodwall in Louisiana. 

The Mississippi River is managed largely by the Military Corps, so it usually options prominently within the invoice, with a twin goal of creating the river extra appropriate for delivery and restoring environmental degradation from flooding, nutrient air pollution and local weather change. 

Kirsten Wallace, government director of the Higher Mississippi River Basin Affiliation, referred to as this yr’s WRDA “a fairly particular one.” She mentioned it contained wins for most of the numerous stakeholders alongside the river, together with shippers, environmental advocates, riverfront communities and federal and state companies – who don’t all the time agree. 

Advocates lauded the regulation’s emphasis on nature-based options. In a press launch, Stephanie Bailenson, coverage workforce lead for The Nature Conservancy, mentioned, “Since 2016, Congress has directed the Corps to contemplate pure and nature-based options alongside or as a substitute of conventional infrastructure. This newest act continues that development.”

However all of those initiatives are solely promised, as a result of funding doesn’t come till later, when Congress appropriates it. Many initiatives approved in earlier variations of the regulation are nonetheless unfunded, in line with the Congressional Analysis Service.

Right here’s what is going to have an effect on the river within the Water Assets Improvement Act of 2024: 

Examine of flood danger on the higher Mississippi River

The regulation authorizes a large-scale examine of flooding on the Higher Mississippi River System, which incorporates the Mississippi River from its headwaters to the place it meets the Ohio River at Cairo, Illinois, in addition to the Illinois River and parts of some smaller tributaries.

The higher river has seen two main floods in the previous couple of years; one in 2022, and one in 2019, which lasted for months and brought on billions of {dollars} in injury. 

The examine’s chief aim: determining cut back flood danger throughout your entire river system, as a substitute of counting on municipalities to attempt to remedy flooding issues themselves, which can typically have impacts downstream. North of St. Louis, for instance, levees constrain the river to guard communities and helpful farmland from flooding – and some levee districts have raised these levees greater, safeguarding themselves however successfully pushing floodwaters sooner downstream. 

“This plan permits extra of a complete approach for levee districts to enhance what they presently have … in a approach that doesn’t put them ready to be adversarial or simply impose danger elsewhere,” Wallace mentioned. 

She mentioned the examine can be a problem, however that levee districts are looking forward to options as flood dangers and heavier rainfall enhance. 

As soon as the examine receives funding, it will likely be led by the Military Corps’ St. Louis District, Wallace mentioned. It’ll solicit enter from cities, cities and ports alongside the river, recreators, the delivery trade and federal environmental companies just like the U.S. Fish and Wildlife Service and the U.S. Geological Survey.

Flood initiatives for cities from the headwaters to the delta 

Cities and cities alongside the river might get assist for the localized results of flooding too, because of a number of initiatives approved by the regulation. Upstream, that features La Crosse, Wisconsin, which is able to enter into an settlement with the Military Corps to check the position of the town’s levees, which have been constructed round the river’s file flood in 1965. 

“We have now to have a watch on sustaining what we’ve acquired and searching towards the longer term and no matter circumstances the river would possibly bear to be ready as greatest we are able to,” mentioned Matthew Gallager, the town’s director of engineering and public works. “As a result of clearly, nature goes to win.” 

Downriver, Louisiana secured the most important challenge authorization inside the regulation. To guard communities in St. Tammany Parish, a county north of Lake Pontchartrain, Louisiana plans to construct a $5.9 billion levee and floodwall system totaling 18.5 miles in size to guard over 26,000 constructions, most of that are household houses. 

The St. Tammany Flood Threat Administration Venture is slated to obtain $3.7 billion in federal funding. The opposite 35% will come from non-federal sponsors, such because the Louisiana Coastal Safety and Restoration Authority (CPRA). 

“By authorizing the St. Tammany challenge for development, Congress acknowledges once more the nationwide significance of Louisiana and that CPRA can work with the Federal Authorities to execute a multi-billion coastal safety challenge efficiently,” mentioned CPRA Chairman Gordy Dove.

The regulation additionally authorizes a federal examine of the Lake Pontchartrain Storm Surge Discount Venture, a element of Louisiana’s Coastal Grasp Plan meant to guard 9 parishes bordering the lake. The Military Corps will examine whether or not the proposed challenge to cut back flood danger is within the federal curiosity. 

Different accepted flood management initiatives can be funded alongside the decrease Mississippi River and its tributaries, together with the Ouachita River in Louisiana. A number of counties in Mississippi will even obtain funding to enhance environmental infrastructure, reminiscent of water and wastewater programs. 

Close to Memphis, the invoice authorizes the Hatchie-Loosahatchie Ecosystem Restoration challenge, which covers a 39-mile stretch of the decrease Mississippi River. The challenge goals to handle flood dangers whereas additionally restoring and sustaining the well being, productiveness and organic variety of the flyway. 

In New Orleans, a examine was approved to analyze ecosystem restoration and water provide points, such because the mitigation of future saltwater wedges that threaten ingesting water and wetlands on the very finish of the Mississippi River. 

Extra help for the Higher Mississippi River Restoration program 

The regulation additionally will increase the sum of money Congress may give to the Higher Mississippi River Restoration program, which funds habitat restoration actions and scientific analysis on the higher river. 

Congress elevated the cash it could possibly direct to the analysis a part of this system by $10 million, bringing the full this system can get to $100 million yearly. 

The enhance “actually is a recognition of the worth of the science … the understanding that has improved about how the system is functioning over the past three a long time,” mentioned Marshall Plumley, the Military Corps’ regional supervisor for this system. 

If given further funding, Plumley mentioned program workers wish to use it to higher perceive the results of the elevated quantity of water that has flowed by means of the river lately. That enhance, partly attributed to wetter circumstances because of local weather change, is altering the river’s floodplain habitats, together with forests and backwater areas. 

A change to how new water infrastructure will get funded

The Mississippi River features as a water superhighway, transporting round $500 million tons of products every year. Infrastructure to maintain delivery operating easily is expensive, and one adjustment in WRDA 2024 is aimed toward shifting the burden of these prices. 

Taxpayers have been funding inland waterway infrastructure for almost two centuries, however Congress established the Inland Waterways Belief Fund in 1978, which requires the personal delivery trade to pitch in. 

Immediately, the belief fund’s coffers are stuffed by a 29-cent per gallon diesel tax on business operators that use the Mississippi River and different inland waterways, including as much as about $125 million per yr lately. New development – like wider, extra trendy locks and dams on the higher river – is paid for by means of a public-private partnership: the personal {dollars} within the fund, and federal {dollars} allotted by Congress. 

Till lately, the personal {dollars} coated 35% of recent development prices and federal {dollars} coated 65%. The brand new WRDA adjusts that to 25% and 75%, respectively. 

Advocates for the delivery trade have lengthy believed taxpayers ought to have a much bigger hand in funding development as a result of it’s not simply shippers who profit from an environment friendly river. 

The stability within the belief fund “all the time limits” development that may occur in a given yr, mentioned Jen Armstrong, director of presidency relations for the Waterways Council. 

“We are able to’t afford to have initiatives take three a long time or twenty years to finish,” Armstrong mentioned, “as a result of we now have different locks which are deteriorating.” 

Armstrong mentioned she believes shifting extra of the price to the federal authorities will speed up these initiatives. 

Not everybody helps the price share change, nevertheless, together with American Rivers, which has opposed the creation of recent locks on the higher Mississippi in favor of serving to the river revert to extra pure processes. 

Kelsey Cruickshank, the group’s director of coverage and authorities relations, referred to as it “a disappointing growth that continues to offer brief shrift to the unbelievable ecosystem of the world’s third-largest freshwater river system.”
