The Benchmark Farm Program - A Method for Estimating Irrigation Water Use in Southwest Florida

Description: From introduction: The purpose of this report is to present irrigation water-use data for selected farms and to show how these data are used to estimate total water use for irrigating various crops in southwest Florida. The study area includes all of the Southwest Florida Water Management District and is about 10,000 miles in size (figure 1). The initial emphasis on benchmark farm locations was in Hillsborough, Manatee, and Polk Counties. As the program continues, new farms are being added in s… more

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana

Description: Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the … more

Effect on Sediment Yield and Water Quality of a Nonrehabilitated Surface Coal Mine in North-Central Wyoming

Description: From introduction: The purpose of this study was to determine the magnitude of some effects of an abandoned surface coal mine on the hydrologic environment. Specific objectives were (1) to define areas of erosion and deposition; (2) to determine if the sediment yield from an undisturbed drainage basin was less than that from a drainage basin partly disturbed by mining activity; and (3) to determine if there were differences in chemical composition of hillslope materials, sediment, and pond wate… more
