White River Fisheries Area is a 10,754
acre property located along the White River from south of Delta in
Bayfield County to 3 miles south of Ashland in Ashland County. It
is riverine habitat transitioning from wooded headwaters, through
grassy swamp and steep clay banks, to a small impoundment. Sajdak
Springs State Natural Area is embedded within the property
boundary. The White River Fisheries Area was established in 1961 to
manage and protect this unique and scenic trout stream and
watershed. This multiple use area is dedicated to trout fishing,
hunting, canoeing and other compatible outdoor recreational and
educational opportunities. Numerous feeder streams, spring ponds,
and outlet flows of several glacial lakes provide the high quality
water for this outstanding trout stream
Here you will witness an amazing artesian well just footsteps
from a picnic area that eventually feed into the nearby
stream
Where is this water coming from?
Porous stone is sandwiched between a top and bottom layer of an
impermeable substance like clay or rock. The artesian water
pressure is kept high due to porous stone being crushed between
impermeable rocks along with the water’s density, and elevation of
recharge zone (gravity). When you get to a point below the entryway
of the flow, there is enough pressure (artesian pressure) to bring
the water up. The water in the aquifer is also under enough
pressure that, when the aquifer is tapped by a well such as this,
the water rises up the well bore to a level that is above the top
of the aquifer called the potentiometric surface. The temperature
of the water from artesian wells is generally constant because of
its depth. Depending on the well depth the water temperature can be
a few degrees above the annual mean
temperature.
