We re-designed topographic mapping of approximately 400 acres of old river channels, bathymetric mapping of the upper Okanogan and lower Similkameen rivers, and located riffles, reaches and pools. We worked cooperatively with landowners and governmental agencies to assess river and riparian habitat conditions at the Similkameen / Okanogan River confluence.

Work included:

  • Survey control and right-of-way boundary determination
  • Corridor topographic survey, surfacing, modeling/mapping
  • Bathymetric surveys and sedimentation mapping
