| Abstract/Description or Keywords |
This report presents the results of an overview hydrologic assessment of the Similkameen River face units, located north of the Similkameen River from Princeton to Hedley within the Merritt Forest District. Henderson Environmental Consulting Ltd. conducted fieldwork October 1999. There has been a low amount of forest development in the face units and there is no development proposed over the 5-year period to 2003. The study area occupies dry southfacing slopes, without major hydrologic concerns. Many channels on the map were not located in the field and it is likely that much of the area drains sub-surface to the Similkameen River. The Litcoola Creek was stable with mossed rocks and stable banks. Both the Iitcoola and Arcat Creeks were dry at the highway at the time ofthe survey. One moderate sediment source was observed in the field, which can be mitigated by seeding the cutbank, installing a sump at the culvert inlet, assessing the crossdrain frequency and armouring the fillslope at the culvert outlet. There are no new proposed roads or blocks planned up to the year 2003. No riparian harvesting has occurred around face unit mainstems and no mass wasting events were identified in the Similkameen River face units. Because of the size of the Arcat Creek or Iitcoola Creek drainages, it would be appropriate to delineate these two areas for separate hydrologic analysis in future assessments. landslide, watershed assessment, erosion, riparian |
