“It was … managed well, pre-contact,” said Paul Sieber, the Ditidaht First Nation’s natural resource manager. The area not only holds cultural significance for Ditidaht because of the salmon, but for the many traditional resources it provided for the people, said Sieber.When Mike Wright, a biologist and owner of M.C. Wright and Associates Ltd., began research at Cheewaht Lake watershed in 1984, he said the streams were in “pristine form” before industrial logging.
“You’re taking water that would have been more concentrated to transport sediment, and now you’re losing that because it’s going elsewhere,” said Wright. “There’s all these things that get layered on that make incubation success very difficult.”Article content Sediment traps were built at the top of S-2 and S-3, where gravel and woody debris would be held and manually emptied. Wright said that the basin filled almost annually.

But you have to establish a split where the two creeks diverge from one another in a way that’s going to actually last,” said Abbott. “What wood does, one of its big functions in a creek like this, especially a creek that can move a lot of material … it’s the driver of the habitat,” said Abbott.“We tried to do what we could with the materials that were on site,” said Abbott. “We also tried to keep with the esthetic of a park, where you have this kind of natural look.”
