2002 and 2003 Upper Klamath River Water Temperature Monitoring

The Bureau of Land Management (BLM) conducted water temperature monitoring at various sites in the Klamath River in 2003 and 2003. The objectives of this effort were to (1) characterize spatial and seasonal trends water temperature trends in the Upper Klamath Wild and Scenic River and adjacent river reaches and (2) provide high quality water temperature data for use by stakeholders in the ongoing FERC relicensing and TMDL processes.

In addition to summaries of the water temperature data, two other data sets are presented in this report. Instantaneous (collected every 30 minutes) and average daily streamflow is monitored by the USGS, and is provided herein to provide context for interpreting water temperature trends. Air temperature was monitored by the BLM at the USGS stream gauge. This data also helps explain observed water temperatures.
