0 Comments Another gravel dig that started yesterday in the Fraser River is again stirring up environmental concerns for fish habitat.
But officials at Emergency Management BC in the public safety ministry said the way the gravel is removed from Harrison Bar will actually “enhance” fish habitat, “maintain” the river’s flood profile and lower it over time.
“It’s a good flood protection project,” Glen Thompson, EMBC’s director of strategic mitigation programs, said yesterday.
He said the project is part of an ongoing strategy of gravel removals and dike improvements that will lead to better flood protection over the long term. In the short term, the project will lower the river at the site by .1 metre and improve the flow of the river over the gravel bar.
But Frank Kwak, president of the Fraser Valley Salmon Society that sits on an ad hoc committee opposed to gravel removal in the Fraser River, said the project “has very little to do with flood protection.”
“If they want to do something about flood protection, why don’t they raise the dikes,” he said. “Why do they keep buffaloing the people that it’s for flood protection. That’s just not the case.”
He pointed to an earlier study that concluded millions of cubic metres of gravel would have to be removed at one time to reduce the river’s level by an inch. About 155,000 cubic metres of gravel and sediment were approved for removal from Harrison Bar following a review of the environmental impact by federal fisheries.
The report found the project would have a “negligible” impact on fish habitat and is “not likely to result in significant adverse environmental effects.”
The report also stated any damages to habitat caused by the removal would be repaired by the river itself as new gravel and sediments arrive in the next freshet.
Kwak said even if that is true, it doesn’t take into account the fish that are “holding on to those gravel bars right now.”
Fisheries biologist Marvin Rosenau said he is concerned the Harrison project will disturb spawning habitat for the fragile white sturgeon population and lead to its collapse.
Fraser River Sturgeon Conservation Society officials could not be reached for comment at press time. The report stated the impact on sturgeon is expected to be “negligible.”
The B.C. government is spending $263,000 to build a temporary bridge so contractor Lehigh Aggregates can reach the site.
An independent environmental monitor on site will have the authority to stop the work if environmental concerns arise.
