Characteristics
Hydrological
Capable of yeilding 5 -100 gpm. Most having a hydrologic connection
with the stream. Water is commonly hard with varying amounts of
Ca, Mg, HCO and SO It is generally more mineralized than adjacent
stream.
Yields up to 400 gpm but for the most part much less. The water is
commonly saline, with Ca- Mg -SO or Na HCO Source for stock and
domestic wells.
Source of water for stock and domestic wells.
Source of water for stock and domestic wells.
Source of water for stock and domestic wells, locally yielding > 25 gpm.
Source of water for stock and domestic wells.
Sandstones yield saline water, not generally considered source for wells
Yields water from fractures and solution cavities, yields of >2.000 are
known, but extent of high yielding potential not known.
Small yields of potable water at depths < 2,000 feet
Yields water from fractures and weathered material, source of water for
both domestic and stock wells, generally yielding < 1 0gpm.
