Gamble's partner, Alissa Hensen, posted a moving tribute on Instagram.
The accident happened when the three hiked up Shannon Falls and went into one of the pool systems nearby for a swim. Gamble and Lyakh then reportedly jumped into the water in a failed attempt to rescue her.
Gamble, born in Richmond and living in Vancouver, was one of several people in a popular YouTube travel vlog called High On Life.
"The world has lost a great human being with the passing of Ryker Gamble".
"Obviously as you invite more people into the backcountry just by nature of numbers you're going to have more situations where this type of thing may happen".
Banks said the bodies were discovered Tuesday evening, hours after the trio slipped and fell 30 metres into the pool.More news: Cruz Pitches Mike Lee as Justice Kennedy’s Replacement on Supreme Court
Gamble was among a group of young men who earned worldwide headlines in 2016 after being charged by authorities in Wyoming with misdemeanours for walking off a boardwalk in Yellowstone National Park to get closer to the landmark's iconic Grand Prismatic Spring.
The adventure group's core members were a trio consisting of Gamble, Lyakh and a third surviving friend. A post last month showed Scraper and Lyakh celebrating five years together.
A delicate search and rescue operation stretching into two days turned into a recovery mission.
Cpl. Sascha Banks says teams from several agencies have so far been unable to spot the hikers in the pool system.
Squamish Search and Rescue (SAR), Lions Bay SAR, BC Ambulance, Squamish Fire, TEAAM, BC Parks, and Squamish RCMP attended the scene in order to coordinate search efforts.
"The RCMP and Squamish SAR have transitioned to a recovery of the bodies from the pool but the terrain is extremely hard, very unsafe, and the water flow will be heavy with the warm temperatures today, increasing the risk to those in the recovery effort", police said at the time.
Squamish Search and Rescue spokesman John Willcox said a young woman was swept into one of the pools about noon Tuesday.
