Why don some counties have their own ground-water or surface-water indicator sites?
Currently, the USGS does not have suitable ground-water observation wells located in all counties of the Commonwealth. Until such time that each county has it’s own representative ground-water observation well, we have determined which adjacent county’s well best represents the ground-water conditions of the county that lacks an observation well. We also have determined that those surface-water sites within certain counties currently do not best represent that county’s overall streamflow conditions. Sometimes the only surface-water sites within a county are in locations that are affected by regulation or diversion and therefore do not represent “natural” conditions.
