An application of surface geophysical techniques to the study of watershed hydrology

The applicability of geophysical methods to experimental watershed research is demonstrated by a study of a 106-acre forested watershed in central Pennsylvania. Data from a shallow seismic refraction study and an electrical resistivity study of the watershed were used to determine the depth of soils, their volumes, depth to bedrock, configuration of the bedrock surface and delineation of the bedrock surface and delineation of the water table. With this information on the subsurface conditions, the hydrologic properties of the watershed were described in greater detail. This information will be of value in explaining the watershed's response to various watershed treatment practices that eventually will be used.

Measurement of stream discharge by wading

Most years the U.S. Geological Survey (USGS) makes over 50,000 stream discharge measurements. Over 75 percent of those measurements are made by wading streams and using the velocity-area method. This PowerPoint presentation describes how stream discharge should be measured when wading and using the velocity-area method. It is intended as a learning and reference tool for anyone responsible for making wading discharge measurements.

Streamflow characteristics of the upper Columbia River basin, Montana, through 1979

Statistical summaries of streamflow data for selected stream-gaging sites presented in this report aid in appraising the hydrology of the upper Columbia River basin in Montana. Streamflow records are provided for 54 gaging stations for the period of record. Streamflow records for five gaging stations were compiled into separate periods related to changes in regulation after data collection commenced. The entire period of record, the period before regulation, and the period after regulation are presented for comparison. For each gaging station selected for this report, a brief description is given for station location, drainage area, period of record, revisions of previously published records, type and history of gages, regulation and diversions, and extremes of discharge. These data are followed by tables of monthly and annual flow statistics, flood-frequency data, low-flow and high-flow frequency data, and flow-duration information. (USGS)

Streamflow losses to Madison Group rocks in the Little Belt and Big Snowy Mountains, Montana

Four streams originating in the Little Belt and Big Snowy Mountains in central Montana were measured in 1975 to determine streamflow losses across outcrops of the Madison Group (Mississippian age). Based on streamflow data obtained for 39 months at two streamflow-gaging stations on the Middle Fork Judith River, the average daily loss was 9.1 cubic feet per second or about 6,600 acre-feet per year. Seepage measurements on other stream reaches indicated losses of 7.6 cubic feet per second on the south Fork Judith River, 9.2 cubic feet per second in Yogo Creek, as much as 64 cubic feet per second in Dry Wolf Creek, and about 60 cubic feet per second in Rock Creek.

Streamflow characteristics of the Hudson Bay and Upper Missouri River Basins, Montana, through 1979

Statistical summaries of streamflow data for selected gaging stations are presented in this report to aid in appraising the hydrology of the Hud son Bay and upper Missouri River basins in Montana. Streamflow records are presented for 122 gaging stations for the period of record of each station. Streamflow-record collection in the Missouri River basin began in 1890 at Fort Benton, Montana. For each streamflow-gaging station selected for this report, a brief description is given for station location, drainage area, period of record, revisions of previously published records, type and history of gages, regulation and diversions, average discharge, and extremes of discharge. These data are followed by tables of monthly and annual mean discharge, flood-frequency data, low-flow and high-flow frequency data, and flow-duration information.

Streamflow characteristics of the Yellowstone River Basin, Montana, through 1976

Statistical summaries of streamflow data for selected stream-gaging and crest-stage gage sites are presented in this report to aid in appraising the hydrology of the Yellowstone River basin, Montana. Streamflow records presented for 45 gaging stations and 45 crest-stage gages for the period of record. Streamflow record collection in the Yellowstone River basin began in 1889. For each gaging station selected for this report, a brief description is given for station location, drainage area , period of record, revisions of previously published records, type and history of gages, regulation and diversions, and extremes of discharge. These data are followed by tables of monthly and annual flow statistics, high-flow and low-flow frequency data, flood-frequency data, flow-duration information, and for natural-flow sites selected basin characteristics. For each crest-stage gage, the brief description consists of location, drainage area, period of record, and type and history of gage. This information is followed by tables of flood-frequency data and selected basin characteristics.

Water-quality investigation near the Chico and Hunters geothermal lease-application areas, Park and Sweet Grass counties, Montana

Water quality in and adjacent to geothermal lease-application areas near Chico and Hunters Hot Springs was investigated during two surveys in October 1976 and April 1977. The resulting data were needed to evaluate the effects of proposed geothermal exploration and development on the Yellowstone River and its tributaries. Waters from the two hot springs, the Yellowstone River, and its tributaries that drain the proposed lease areas are generally suitable for drinking, except for excessive concentrations of fluoride and hydrogen sulfide in waters from Hunters Hot Springs. The water from Chico Hot Springs is suitable for irrigation, but the water from Hunters Hot Springs presents a very high sodium and a medium salinity hazard and is generally unsatisfactory for irrigation. The effect of the thermal waters on streamflow and chemical discharge of the Yellowstone River during the surveys was negligible and less than the accepted error of measurement. Production of higher volumes of more concentrated water can be expected to accompany testing and development of the geothermal resource.
