Two channel monitoring stations - upstream and downstream - were installed in Chataway Creek in September 2000 and re-surveyed in 2001 and 2003. Sediment input to Chataway Creek was also surveyed each year. The overall objective of the monitoring program is to identify changes in channel morphology related to proposed and ongoing forest development. After three years of measurements, generally, both the Upper and Lower channel stations remained relatively stable throughout the monitoring program. Data collected suggests the channel may have been slightly scoured over the course of the study, however; the observed channel changes are likely within the error range of the methods used. No forest development occurred during the project period, although the deactivation of a portion of the Chataway FSR occurred immediately above the Lower station. Therefore, the results of this three-year monitoring program can serve as baseline data for the watershed. Following any large-scale watershed disturbance, a re-survey of the monitoring stations can allow quantitative comparison of channel conditions following disturbance. Based on the current forest development plan, a suitable time frame for resurvey would be in the summer of either 2005 or 2006 when the ECA will double to over 35% at the Upper station and at the Lower station, the ECA will increase by 5% to 26%. Another disturbance type to re-survey is the summer after an unusually larger freshet when channel change is expected. Therefore, it is recommended to retain survey pins at the channel stations to be re-used in future surveys. |
