Using satellite imagery to estimate consumptive water use from irrigated lands in the Milk River Basin, United States and Canada

The U.S. Geological Survey, with the support of the International Joint Commission, and in cooperation with Alberta Environment and Parks, Blackfeet Nation, Environment and Climate Change Canada, and Montana Department of Natural Resources and Conservation, is leading a project that should improve information available to apportion water between Canada and the United States in the St. Mary and Milk River Basins. One component of the water budget, consumptive use of irrigation water (the amount of supplemental water used by crops), can be estimated at 100-meter resolution almost every week using imagery recorded by satellites from 1985 to present (2021) and weather data, when conditions permit. Better estimates of consumptive water use should improve understanding of water availability and use in the basin and should assist with water apportionment procedures.

The Flaxville gravel and its relation to other terrace gravels of the northern Great Plains

In Nebraska and South Dakota there are widespread deposits of gravel and other material, largely superficial and generally uninitiated, known as the White River, Arikaree, Ogalalla, and other formations, which range in age from Oligocene to Pleistocene. West of these deposits, on the flanks of the Rocky Mountains, are several high plateaus covered with gravel, whose age, though not know, is generally regarded as Pleistocene.
