What is our water quality?
Basis: Water in Routt County is essential for agriculture, municipal, utility, recreation,
wildlife, and aquatic life. It is important to identify and track both quality and quantity of
water.
The United States Environmental Protection Agency (EPA) classifies some bodies of
water as having quality issues, and therefore places them on a 303(d) list for monitoring
under two categories: 1) Body (lake or pond) and 2) Segment (stream or river). The
data available for quality of water reflects reporting on heavy metals, bio-hazard waste,
and sediment. Using GIS information, The Team identified segments in the Core
Counties, and then evaluated stream flow based on 303(d) rankings of L (low) M
(medium) or H (high) to weight the overall quality.
Comparable data in all Core Counties was collected and estimated total stream flow for
the counties was calculated. Estimated stream flow for 303(d) water segments was also
collected.
Using GIS information, the Team isolated stream segments in the Core Counties, and
then weighted the EPA rankings to produce a measurement for this category.
NOTE: The Colorado Department of Health does not test all viable water sources.
Because this data only reflects select water segments that are “at risk” for quality to
some degree, the measurement and graph below do not reflect a blanket rating of the
overall quality of water in each county. For example, the two water segments in Routt
County that are 303(d)-designated by the EPA are Elk Creek in the California Park area
and Dry Creek below the Seneca Mine near Hayden. Neither of these two segments are
either significant in length or use, i.e. neither is used for recreation or drinking water.
The fact is that Routt County (and possibly other Core Counties as well) has a very
good overall water quality, because the primary sources that are used for recreational
and drinking purposes have not been determined to be impaired according to the EPA
303(d) List. For the purpose of this Index, this data enables for the tracking of changes
over time for the bodies of water within each county which have quality issues. More
data will be added and tracked in the Index as it becomes available, i.e. measurement
of sediment, aquatic life, etc
