INTRODUCTION
High summertime temperatures have been known to be a problem for spawning salmon in the Horsefly River for several decades. However, a formal Interior Watershed Assessment Procedure (IWAP) completed in 1998 did not directly address this issue because there is no accepted procedure for assessing stream temperature in British Columbia. A key question has been the possible effect of temperature increases in small streams on the temperature of larger fish-bearing waters. This is a concern because reserves are not required on S4, S5, and S6 streams by the Riparian Management Area (RMA) Guidebook.
To help answer this question a literature review was completed on the effects of forest practices on stream temperature. Results of the review are documented in a technical report (Teti, 1998) that is available to forest managers. This extension note provides a summary of that report.
