How to symbolize streams layer from `bcfishpass` `.gpkg` dump

[NewGraphEnvironment]

looks like latest bcfishpass qlr file uses views for linear habitat models but stream layer currently exported perhaps will not have enough detail for symbology? Also, we need to be able to symbolize bt_access model (at a minimum - RB would likely be better as applicable in near all study areas) to understand what is likely habitat using phone in the field.

Yes, the QGIS file depends on habitat modelling (discharge/CW based spawning/rearing) but current .gpkg export is just the access models for salmon and steelhead. The export contents are based on what the Province is willing to publish/support at this time, and not related to the QGIS file at all. Note also that publication in the DataBC catalogue is currently on hold, hopefully we will get a green light soon.

So to support field mapping, I can dump whatever we want to another file in the same spot.

Regarding BT and RB, how about a combined access model like this? https://github.com/smnorris/bcfishpass/blob/main/model/access/sql/model_access_ct_dv_rb.sql Includes observations of BT/CT/DV/RB and uses 25% as the max gradient passable.

Another option recently discussed has been using observations of all species and a 25% threshold.
