The East Nishnabotna Watershed.

The East Nishnabotna Watershed.

The East Nishnabotna River Watershed (ENRW) encompasses 696,400 acres and touches 10 counties in Southwest Iowa. The ENRW is part of the Nishnabotna Basin, which drains to the Missouri River, a crucial water body that provides feeding, breeding, and resting areas for hundreds of species of birds and fish. The ENRW is located in the Southern Iowa Drift Plain Region, with broad rolling uplands and deep valleys adjoining woodland areas that provide abundant habitat for wildlife and recreation.

In the early 1900s, farmers began to transform the landscape from prairie to farmland. Channel straightening during this time altered the naturally meandering streams. About 75% of the lower 100 miles of the East Nishnabotna River were straightened. The fertile loess soils are intensively farmed and susceptible to erosion and streambank degradation. The predominant land use is for row crops, with about 76% of the watershed in a corn-soybean rotation.

The Iowa Water Resources Coordinating Council selected the ENRW as a high priority area for implementation of conservation practices outlined in Iowa’s Nutrient Reduction Strategy. In 2011, a comprehensive plan was developed for seven counties in the Loess Hills region in Western Iowa, including Fremont in the East Nishnabotna River Watershed. The plan looked at changes in the area during the last 20 years and set goals for the future, including woodland and prairie restoration. The Iowa Watershed Approach will build upon the 2011 comprehensive plan and will complement the goals established for the watershed.
