Caring Enough to Make A Difference



Stream Monitoring and Lake Water Testing

The Coalition conducts stream monitoring using the protocols established by the IDAH2O Master Water Stewards program.  IDAH2O is a volunteer, citizen scientist effort to collect basic water quality data for Idaho streams. The program is offered through University of Idaho Extension and provides unique opportuniies to learn about and document regional water issues.  To learn more about this program and their resources, see



Lake water testing is performed several times each summer by local residents to test for water clarity, temperature, phosphorus content and dissolved oxygen levels. The historical trends of these readings show that Hauser Lake has become warmer, with higher phosphorus content, lower dissolved oxygen levels and poorer water clarity.  These trends have negatively affected the cold water fishery (i.e. trout) and recreational use of the lake for swimming and other water sports.
