River Watch Data

River Watch data is available to the volunteers, watershed managers and the public. When combining data from multiple sources or using others data for different data objectives it is best management practice for the user to ensure field, laboratory and associated methods and data quality are sufficient to combine for each data objective that may be the same or different from original data sets. Data is a greater asset and of higher value, when provided sufficient meta-data so users can appropriately determine other uses.

River Watch provides as much meta-data as possible, but it is the user's responsibility to ensure appropriate use for other objectives. Data users are responsible for understanding River Watch data objectives, methods and procedures in order to make informed and appropriate decisions regarding data use. A downloadable pdf provides relevant information about River Watch data on the Public Reports Page. Availability of all types of data for each type and duration of sample frequency will vary for each station, from one event to twenty years of monthly sampling.  

The type of data that is available from River Watch includes:

  • Field data such as temperature, dissolved oxygen, pH, alkalinity and hardness

  • Dissolved and Total metals including (Al, As, Ca, Cd, Cu, Fe, K, Mn, Mg, Na, Se, Zn)

  • Nutrients including (ammonia, nitrate-nitrite, total nitrogen, total phosphorus, chloride, sulfate and total suspended solids)

  • Macroinvertebrate species, identified to species genus, semi-quantitative methods and associated metrics

  • Macro (reach) and micro (macroinvertebrate kick area) physical habitat assessment

  • Station information (location, driving directions, elevation, gauging station, WBID, Watercode, County, etc.)

  • Organization information (groups, projects, quality assurance and performance reports, etc.

  • Quality assurance

A special download is available that includes method detection limit (MDL), lower reporting limit (LRL), detection condition, a qualifier field for every chemical result, where results >MDL but < LRL are reported that actual result versus a zero.  All ot​her exports provide the MDL and LRL values in a FAQ download and results >MDL and <LRL are reported as zero.

​​River Watch Watershed Reports and Data Displays

The primary data user for River Watch data is the Clean Water Act, which protects drinking water, recreation, aquatic life and agriculture uses.  The state agency that administers the Colorado Clean Water Act is the Colorado Department of Public Education and Environment (CDPHE).  CDPHE divides the state into major basins and each river in the basin into segments in order to regulate discharge permits, monitor and assess attainment of uses in state waters. Rivers, wetlands, lakes and reservoir segments are Water Body IDs.

River Watch has produced an assessment of Clean Water Act uses on Water Body IDs with River Watch data. If all Water Body ID segments have data then an entire watershed would have a complete assessment. We update these every five years based on the basin the Water Quality ​Control Commission is conducting a rulemaking hearing that year.
