During the spring of 2014, a remnant railway bridge abutment and historic railway bed that makes up a popular BC Parks trail located in Coquihalla Canyon Provincial Park near Hope BC partially collapsed subsequently sliding into the Coquihalla River. Deposited rocky material from the abutment location has modified a velocity barrier at the location known locally as Othello Falls. Othello Falls acts as a seasonal migrational barrier to fish passage into the upper Coquihalla River. Large, human modified rock was opportunistically drilled and split using (NXburst TM), a low velocity, non-restricted blasting charge, at low summer water levels (Sept 2017). With the rocks cleared the steelhead can once again return to their spawning grounds.
