The limit of WELL is the extent of the hole in the ground.
If WELL is a water well and is landmark,
If WELL is a water well, and is in an arid area, and is ≥ 0.25" from a building,
If WELL is a water well, and is in an arid agricultural area, and is used for irrigation,
If WELL is a heat well,
If WELL is a producing water well, and is within an area of closely spaced wells, and is
necessary to accurately represent the pattern of wells (see Source Interpretation
Guidelines to determine how to accurately represent the pattern), then capture.
Source Interpretation Guidelines
If WELL is within an area of closely spaced wells,
Then first capture named WELLS, then those that are on the perimeter of the
area, then those that are most prominent, then finally capture a representative
pattern of WELLS internal to the area. Capture as many as can be shown in
correct position. The symbols must not overlap.
If WELL is associated with WINDMILL,
Then do not capture WELL. See WINDMILL.
Irrigation wells are often enclosed in a structure and are usually found in wide
areas along or at the end of field roads. They may be evidenced by a wide wet
collection area leading into a linear channel.
If WELL produces a product other than water or heat,
Then collect in the theme Built-up.
Do not capture dry wells.
Water tunnels in Hawaii, shown with the adit symbol, are captured as WELL.
