The upper portion of the Troublesome Aquifer is the sole source of water for domestic use in the Greater Pole Creek Basin, situated in the western portion of the upper Fraser River Valley in Grand County, Colorado. Data from drilling records for wells installed near and within recent home developments, municipal water-suppliers, water-quality records, and published reports are summarized as an initial synthesis of aquifer water quantity and quality. In spite of persistent drought and increased domestic aquifer-water usage, aquifer water storage remains robust with water levels little changed during the past 25 years. Water-quality data indicate substantial variability with depth beneath the top of the aquifer. Data...

The Shingobee Headwaters Aquatic Ecosystem Project is a long-term, multi-disciplinary monitoring and research study of a 28-square-kilometer headwaters watershed in north-central Minnesota that began in 1978. Emphasis is on processes related to hydrology, limnology, geochemistry, and watershed ecology and the land-water and atmosphere-water interfaces. Lakes are a substantial focus and integrator of many of the physical, chemical, and biological processes that occur within watersheds. Large volumes of groundwater discharge provide resilience to lakes and wetlands in response to anthropogenic and climatic influences. Minnesota, located in north-central USA, has been both warmer and wetter than normal during the past...

Rates of flow across the sediment-water interface (seepage), measured every 5 seconds with an automated seepage meter and summarized every minute with a digital datalogger, are presented for 17 measurement locations at Newtown Creek, NY. Final values are presented in cm/day. An electromagnetic seepage meter, custom made for USGS by Quantum Engineering, was capable of measuring seepage averaged each minute with an accuracy of +/- 0.5 cm/d. Deployments at each location lasted at least two tidal cycles. Three ESM systems were available but most of the time only two systems were operated simultaneously, requiring several weeks to obtain measurements at all 17 locations. Data are presented in an Excel workbook composed...

Efficiency of seepage meters, long considered a fixed property associated with the meter design, is not constant in highly permeable sediments. Instead, results from this study indicate that efficiency varies substantially with seepage-bag fullness, duration of bag attachment, depth of meter insertion into the sediments, and seepage velocity. Efficiency also varies substantially in response to variable hydraulic conductivity. The first worksheet titled "Literature efficiency" presents seepage-meter efficiency values from the literature to show the progression of efficiency versus time. The remaining 7 worksheets present time-series data showing seepage-meter efficiency related to several different tests: (1) flow...
