Utah Water Watch Data Summary
This is a quick report of some water quality data collected by statewide UWW volunteers.
Reports are organized by watershed and graphs will help volunteers and others view the trends in their area. You will notice clear temperature increases through the summer as well as some E. coli spikes in the summer months.
Red lines on the graphs indicate the standard maximum tempearature for the majority of streams and rivers in the watershed and E. coli recreational limits.
We will be generating a more detailed report in the near future, but in the meantime, click on your watershed below to see the graphs. Let us know if you have any questions or comments or would like to see more about your site.
Major water quality issues: nutrients, sedimentation, fecal coliform bacteria, high water temperature, and low dissolved oxygen
Pollutant sources: grazing, agriculture, animal feeding operations, wastewater treatment, roads, urban development, logging, oil and gas exploration.
Most of the streams and rivers in this watershed are protected as 2A for cold water fisheries. Note the temperature data collected all falls under the 20°C standard and E. coli below the 408 colonies/100mL standard for recreation.

Major water quality issues: sediment, total phosphorus, nitrogen loading and erosion
Pollutant sources include: agriculture, habitat modification, hydromodification
We do not currently have enough data in this watershed to make a graph. We currently have an active sample site on Coal Creek with a couple entries for the year. We will be holding a training in Cedar City this spring and encourage more sites to boost the database.

Major water quality issues: sedimentation, high levels of total phosphorus, and low dissolved oxygen.
Pollutant sources: grazing, agriculture, animal feeding operations, wastewater treatment, roads, urban development, logging, oil and gas exploration.
Watersheds are subdivided into two smaller watersheds - Lower Weber River and Upper Weber River
Most of the streams and rivers in this watershed are protected as 2A for cold water fisheries. Note the temperature and E. coli data collected had a few hits above the standard maximum especially in the Lower Weber Watershed. This may be attributed to the unusually low flows that occurred in the watershed over the summer months.

The Jordan River is a diverse watershed affected largely by urban impacts. Graphs are broken down into smaller sub watersheds.
Water quality issues include: metals, total dissolved solids, E. coli, high water temperatures, high levels of ammonia, and low dissolved oxygen.
Major pollutant sources include: failing septic systems, industrial discharges, illegal dumping, equipment cleaning,
agriculture, and stormwater from roads and parking lots.
Note: most of these creeks are designated as cold water streams, however the Jordan River where all these streams collect, is designated warm water stream and has a standard maximum of 27°C. From this data, all measurements are below the 20°C cold-water max, except Spanish Fork River which is right at the limit.

Water quality issues include: metals such as selenium, total dissolved solids, increased water temperature and radiation.
Pollutant sources include: mining, agriculture, and natural occurrences.
To learn more about the Southeast Colorado River Watershed, go here.
Water quality issues include: metals, total dissolved solids, temperature and E. coli.
Sources of pollutants include: agriculture, drought, hydromodification, urban runoff and sewers, natural causes.
To learn more about the Lower Colorado River Watershed, go here.
Water quality issues include: sediments, erosion, high total phosphorus, and low dissolved oxygen.
Sources of impairment include: agriculture, habitat modification, natural sources, hydrologic modifications.

Major water impairments: include high water temperature,low dissolved oxygen, high phosphorus levels and high sediment loads.
We have little data for this watershed to report this year. If you in participating and adding to our database, let us know.
