Comments, Etc.
Two springs exist in this area and both have
been referred to as S-7. Data from 1983 is
from the "Peter Spring" which has a very low
flow (max, observed = 0.04 gpm) and is currently
not in use. It is located approx. 250 ft. WSW
of the homestead and issues from an iron pipe
from the aide of the hill. Data beginning in
1987 (& also possibly the original 1979 spring
survey) is from an infiltration gallery placed
in the alluvium and discharging into a clear
well. It is referred to as the "Joshua Spring"
and has a maximum observed flow of 13 gpm. It
is located approx. 30 ft. WSW of the homestead.
Flow of spring fed creek sampled 100 yards
upstream of stock pond.
Composite of several seeps are monitored in
spring fed stream channel. Buried in spoils in
1998.
Flow never observed; sampled from alluvial
clear well; site also known as Olson Spring.
Discontinued 2005.
