Wild Steelhead have been tag and monitored using transmitter in the Skeena river in 80's-90's. Until they reach tidal barrier ( 50 km or 31miles ) upstream from the estuary they move rather slow ( few km per day) and enter the river on the tidal waves. Then, 50-60% fish moves about 7-10 km /day( the rest moves either 2-4 km or 10-14km per day) until they reach Copper river. Once they past Copper majority move 20-25 km, but the rest either slower or faster, with some outliers running 35-40 km ( km NOT miles).
On low summer flows, fish moves faster, with lesser resistance from flowing water ( Usk water discharge was well correlated with fish movement rate), and slower when flow is higher.
Let's remember summer/fall Skeena Watershed fish does not spawn until Spring.
Also, higher temps like 16-17 C ( 61-63F) will slow done fish , where lower, more comfortable summer water temps 50-59 F, increase movement rate. Lots of variables.
As expected Sustat, Babine and upper Morice fish enters the Skeena earlier.
