Stream temperature monitoring has been completed on 13 streams within the District boundaries. Monitoring efforts began in 1991 and will continue through 2017. Prior to 1995 data was collected by students from the Lewiston High School’s volunteer program. From 1995 through 2005 monitoring data was collected by a combination of District staff and volunteers. From 2005 to 2013 data has been collected by District staff. Early monitoring efforts focused within the Tammany, Lindsay and Hatwai Creek drainages. Funding for restoration efforts resulted in an increased monitoring effort in the Big Canyon and Lapwai drainages since 2005.
The District compiled and summarized monitoring data from 1998 through 2012 for all the streams that were monitored in the District. The District’s current stream temperature monitoring protocol can be downloaded here: Stream Temperature Monitoring Gages Protocol - 2013.
The District compiled a monitoring site work plan for the period 2013-2017 which outlines the sites selected for monitoring for a five year time frame.
All stream temperature data (data sets from 1998 through current) is stored on the StreamNet website. For raw data end users will need to access the data from their web site.
