Watersheds and the Management
The Little Blue River Basin begins in the tablelands of Kearney County near Minden. The Basin drainage area totals just under 2,691 square miles or 1,722,200 acres. The principal tributaries of the Little Blue River include the Big Sandy Creek with a drainage area of 638 square miles; Rose Creek, 203 square miles; Spring Creek, 180 square miles; and Pawnee Creek, 126 square miles (view map). The total length of the Little Blue River in Nebraska is approximately 200 miles.
The Little Blue NRD has completed the watershed development plans on several of these watersheds over the years with the primary purpose being for flood control. But with the construction of dams, other benefits have been recognized as well. These include grade and erosion control, groundwater recharge, livestock water, irrigation, fisheries and wildlife and private and public recreation opportunities. These multi-benefit projects lie as silent protectors of the land, capturing storm water runoff and releasing it slowly into the streams and river, thus reducing road, bridge and crop damages, reducing stream bank erosion and downstream sedimentation, and retaining valuable surface water supplies for beneficial uses.
Little Blue River Basin Watershed Activities
The Little Blue NRD has been involved in the development of watersheds for flood control and multipurpose activities since the inception of the District. Altogether, the completed structures in the Little Blue NRD account for:
- 114,133 acres of drainage are controlled with structures
- 1,367 total acres of surface water created
- 18,527 acre feet of stored water
- 1,038 acres of public land area managed by District

Several watersheds were studied by the District over the years with the intention of developing flood control plans. However, due to either a lack of public support, physical limitations, costs or other factors, dams were not pursued in those watersheds. Several areas have not been evaluated and offer some possibilities for future studies if the board chooses.
