Title: Ground-water resources of the lower Yellowstone River 

 valley between Miles City and Glendive, Montana 



Series: USGS Circular 93 



Date: 1951 



This report was part of the series of investigations designed to 

 evaluate the effects of new irrigation projects along the lower 

 Yellowstone River. Areas near Miles City, however, are shown as 

 already irrigated at the time under the Tongue-Yellowstone 

 Irrigation Project. 



The Miles City area is underlain by a structural basin, with 

 groundwater recharge to the west (the Porcupine Dome) and to the 

 east (the Cedar Creek anticline) supporting flowing wells completed 

 in the Fort Union and Hell Creek aquifers underlying the alluvium 

 in the vicinity of Miles City. 



Drainage problems on the Tongue- Yellowstone project were considered 

 minimal at the time, following several decades of irrigation. 

 Water level records are reported for several observation wells 

 within the section of the sampling site, with levels ranging from 

 about 7.5 to about 16 feet below the surface at the time. 



Water quality sampling identified characteristic high-Na water 

 quality from all flowing wells in the study area. It may be 

 possible to identify mixed contribution to wetland water chemistry. 



There is also a discussion of the geomorphology of terraces along 

 the lower Yellowstone, with six terrace elevations above the modern 

 floodplain identified.
