Mississippi Valley

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

United States: Water surplus to persist in Ohio River Valley, emerge on Missouri River

Water surpluses will continue to emerge in southern Michigan and the Ohio River Valley. Exceptional surplus is expected on the Missouri River, western Montana, Idaho, and Washington. Intense deficits will continue in the West and Southwest. Moderate deficits are forecast for Oregon, Kansas, western Oklahoma, and most of Texas west of the Brazos River, with severe conditions in the Panhandle. Missouri, Arkansas, Louisiana, and Mississippi will transition out of deficit, with moderate surplus emerging in Arkansas into surrounding states. Deficits in the Mid-Atlantic States will shrink.

United States: Deficits persist in FL, GA, AK; surpluses ID

The forecast for the next three months shows a significant reduction in the extent and severity of water deficits in the Ohio River Valley, Lower Mississippi Valley, the Deep South, and South Atlantic states. Parts of New England will transition from deficit to moderate surplus. Surpluses are forecast in the northern half of Michigan’s Lower Peninsula, Wisconsin, and Iowa, southern Missouri, southern Kansas, northeastern Oklahoma, and southern Colorado. Extreme to exceptional surpluses are forecast in Idaho and surrounding states, and surpluses of generally lesser severity are expected in California’s northern two-thirds.

ISciences Worldwide Water Watch List May 2017

ISciences Worldwide Water Watch List May 2017

Regions likely to have significant water deficits for the 12-month period from February 2017 through January 2018 include: Florida (US), Brazil, northern Chile, French Guiana, Finland, Estonia, Latvia, northern Africa, Gabon, Saudi Arabia, Qatar, Papua New Guinea, and Tasmania (Australia). Water surpluses are forecast for: Idaho (US), La Pampa (Argentina), western European Russia, eastern Romania, southeastern Tanzania, the Volga River Basin, between the Ob and the Tom Rivers (Russia), and Kazakhstan. This Watch List is based on ISciences Water Security Indicator Model (WSIM) Global Water Monitor and Forecast issued 9 May 2017.

United States: Water deficits to emerge this spring in the Appalachians, the Ohio River Valley, & the Northern Plains

Overall, conditions in many parts of the US are forecast to be drier than normal. Moderate to exceptional water deficits are expected in the East through the Appalachians, the Midwest through the Ohio and Mississippi Valleys, across the Northern Plains and parts of the Central Plains, and in the Southwest. In the summer and early fall exceptional deficits are forecast on the Missouri and Yellowstone Rivers. Surpluses are forecast in Idaho and northeastern Nevada, the shared border of Minnesota and Iowa, the Canadian and Rio Grande Rivers, and southern Florida.

United States: Water deficits to emerge this Spring in Ohio, lower Mississippi Valleys, then upper Mississippi & Northwest

Overall, widespread moderate to exceptional water deficits are forecast for Montana, Wyoming, North Dakota, Minnesota, Michigan, and much of the Mississippi and Ohio Valleys. Surpluses are forecast for the Southern Plains and southern Florida. In April and May deficits are forecast for much of the country east of the Mississippi, and will emerge thereafter across the North, in the Central Plains, Northern Great Plains, and in the West, tracing paths along many major rivers. Though decreasing in severity, widespread deficits will persist through November. 

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
