• L6Discharge and water level records2, move it

  Water Survey of Canada. Flows and levels at Penticton, Okanagan Falls, below McIntyre Dam and near Oliver. There is no active gauge on the mainstem between Oliver and the border. A cleaned daily set is on the data site; the live portal is wateroffice.ec.gc.ca

• L14Okanagan sockeye run timing3, test it

  Wells Dam adult counts, public on Columbia River DART. Counts at Wells include fish bound for other rivers, so Canadian arrivals are lower. Okanagan-specific timing is held by ONA; ask the instructor before relying on it

Not available, and that is the point

If your work needs one of these, assume it. Say where you used the assumption. Carry its uncertainty through to your recommendation. In stage 4, treat these gaps as findings, not as roadblocks.

• The period, size or frequency of the internal seiche in Okanagan, Skaha or Osoyoos Lake. Nobody has published it; consultants hold unpublished measurements.
• The depth and shape of the intakes at Penticton, Okanagan Falls, McIntyre or Zosel.
• Depth-area curves for Skaha and Vaseux.
• Recent deep-water dissolved oxygen profiles for Skaha. Not yet confirmed either way. If it turns up, it joins the library.
