      and flow
    • Bacteria
    • Nutrients, trace metals and major ions
  2. Aquatic macroinvertebrate
  3. Fluvial geomorphology
  4. Riparian vegetation composition & structure
  5. Spring vegetation composition & structure

Water quality data are used to characterize the condition of stream and spring waters, detect trends over time, and identify existing or emerging problems. In SCPN parks, water quality is monitored as an indicator of aquatic ecosystem integrity, as a component of watershed condition, and to document water quality conditions in relation to state and federal regulations. Perennial streams are rare on the Colorado Plateau, and most streams in the region are intermittent or ephemeral. Because of highly varying flows, difficult access, and limited funding availability, water quality data describing SCPN streams and springs are sparse. Information documenting water quality status and trends helps to guide the development of resource management plans and actions designed to maintain or restore surface water quality.

Water quality is influenced by physical and biological conditions such as geology and vegetation, altered by natural disturbance events such as catastrophic fire, flooding or climatic drought, or degraded by a variety of anthropogenic activities. Significant contamination of surface waters can be harmful to aquatic biota and may pose health risks to recreational visitors. SCPN's water quality monitoring program complements ongoing state, tribal, and other NPS monitoring programs, thus contributing to a broader regional understanding of aquatic conditions.

Monitoring Objectives

Specific objectives of water quality monitoring for the SCPN parks are

  • Determine status and trends in selected core water quality parameters (water temperature, pH, conductivity, dissolved oxygen, turbidity and discharge) under base flow conditions at selected sites in priority streams and springs within SCPN parks as a function of flow, season and climatic condition.
  • Determine status and trends of water quality constituents including bacteria, nutrients, major elements, and trace metals at selected sites in priority streams and springs within SCPN parks.
  • Compare water quality data against state standards for chronic exceedences. Multiple exceedences in a year typically indicate non-compliance.

Monitoring Project Status

Water quality will be is monitored quarterly at selected streams in five SCPN parks. Pilot studies were initiated in 2007 and stream water quality monitoring was implemented in 2010. SCPN sends water quality samples to the US Geological Survey's National Water Quality Laboratory for analysis of selected water quality constituents.

SCPN's spring water quality monitoring is integrated with the network's spring ecosystems monitoring and will be implemented in 2018. The Water Quality Monitoring Protocol for Streams and Springs in the Southern Colorado Plateau Network was published in November 2016.
