Acoustic Flowmeter Prototype Evaluation Tests

Description: Summary: "Prototype tests of an acoustic flowmeter system were made in a 24-ftdiam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum (Gibson), turbine model test ratings, scroll-case pressure differential (Winter-Kennedy flowmeter), and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparis… more

Geology of the Calamity Peak area, Custer County, South Dakota

Description: A report discussing and area of 2.5 square miles along the southwest border of the pre-Cambrian granitic rocks complex in the pre-Cambrian core of the Harney Peak region, Black Hills, South Dakota that was mapped to determine the relationship between the granite-pegmatite complex and the pegmatites containing beryl and other industrial minerals. This investigation was part of the U.S. Geological Surveys program for the investigation of domestic beryllium resources and was carried out on behalf … more

Preliminary Digital Model of Ground-Water Flow in the Madison Group, Powder River Basin and Adjacent Areas, Wyoming, Montana, South Dakota, North Dakota, and Nebraska

Description: Abstract: A digital simulation model was used to analyze regional ground-water flow in the Madison Group aquifer in the Powder River Basin and adjacent areas. Most recharge to the aquifer originates in or near the outcrop areas of the Madison in the Bighorn Mountains and Black Hills , and most discharge occurs through springs and wells. Results from the model calculations indicate that the total flow through the aquifer in the modeled areas was approximately 200 cubic feet per second (5.7 cubic… more
