Swan Creek

'reasonable' 151 TDS upstream of Culvert

thin surface scum = not oily ... just doesn't look nice!! will try to test for something

100 Coho eggs from Goldstream River Hatchery were incubated & hatched at Swan Lake Nature House in preparation for release into designated 'enhanced' streambed area. 99 survived the alevin to fry stage.
** Bonus during this activity ***
While collecting samples of invertebrate specimens in/on creek bottom ONE CUTTHROAT FRY (the same size as these coho fry) was discovered ** concluding parallel spawning cycles IN ACTION in Nature!!

bumped into local fish biologist Dave Clough who was excited to share that in the Fall '22 when conducting a Streamkeepers course they observed SEVERAL Coho & Cutthroat fry in this Reach where the Riffles have been constructed :)

consistent turbidity with downstream >> Note: Columbine Culvert running abnormally clear , especially for today's runoff . TDS rapid range from 478-502 .. Try to check w/ Saanich Public Works for positive answer!

obvious swollen waterlevels have hidden the riffles built earlier this year.

water levels and quality are showing positive for the spawning salmon/cutthroat this year. >> no actual fish sightings in this 'lazy reach' but high activity in gravel (redds) above riffles is great to see. And once again, the Blue Heron also tells a tale.

As I approached the test site > disturbed a Blue Heron strutting along the creek bank ... so he flew up through the tree canopy.
Greater water flow from this first precipitation has cleared a lot of the duckweed. Also slight discoloration in water clarity from road runoff.

Riffle restructured with new rock & spawning gravel on Sept. 13/14th 2022
