Fixed Site Sampling
Weekly sampling preformed at a set of sites
determined prior to the beginning of the
sampling season. Some of these sites have
been monitored at weekly or biweekly rates
since 1999, allowing us to compare long-term
water quality trends throughout our county.
Sometimes large storms come through,
snowmelt causes flooding, or drought leads
to increased water temperatures. KCWP
monitors these events to track their impact
on water quality.
When irrigators have issues with the quality
of the water leaving their property, KCWP
assesses the situation, notifies the parties
involved, and then conducts follow-up
monitoring to make sure the problem is
KCWP staff spend a fair portion of their working time in the field during the summer
months. During the winter, the data that was collected in the summer is rigorously
examined and analyzed. Water quality improvements are noted, and areas of concern are
While in the field, staff may be taking turbidity readings, noting staff gage readings,
collecting temperature data, testing dissolved oxygen levels, performing flow
measurements, or documenting water quality issues.
The work we do in the field is the backbone of water quality monitoring, without which we
cannot document the water quality improvements taking place in our county.
In 2022, approximately 27 sites will be sampled on a weekly basis.

Unlike the above sampling methods, data
logging does not require the presence of staff
in the field. Instead, equipment is put in place
to monitor turbidity, temperature, or flow,
the data is stored on a logger, and staff
download the data the next time they are in
