Cree, Mtis trappers and fishermen block highway in northern Manitoba

Around a dozen people from the Opaskwayak Cree Nation and their supporters have erected a blockade on a major highway in northern Manitoba, stopping trucks and equipment bound for a massive hydroelectric development project.

The blockade, whichbegan Tuesday, isat the junction of Highway 6 and Highway 39just south of Wabowden, Man. approximately 600 kilometresnorth of Winnipeg.

The protesters are allowing cars, trucks and bus traffic through,but they claim to have turned back semi-trailers and equipment that were en route to the construction site of Manitoba Hydro'sKeeyask Generating Stationnear Gillam, Man., a further 500 kilometresnorth.

The protesters are mainly members of the Opaskawayak Cree Nation Local Fur Council and the Opaskawayak Commercial Fishery Co-op, two groups that have been attempting to negotiate a settlementrelated tothe construction of the Grand Rapids Generating Station over five decades ago.

They've also been joined by people from theMisipawistikCree Nation and Mtis from Grand Rapids, Man.

"This is for land that was damaged in 1960 1.5 million acres of prime trapping and fishing area, when Hydro built the Grand Rapids hydro generating station," said John Morrisseau, who isfrom Grand Rapids.

The fight for compensation

Construction of the Grand Rapids generating station began in 1960 and lasted five years until it was operational.

The dam, which was built on the Saskatchewan River, required thousands of kilometresof land to be flooded much of it trapping and fishing grounds used by First Nations, including people from Opaskwayak Cree Nation.

The trappers and fishermenfrom that community say that because of the changedlandscape they now have to travel up to 150 kilometresjust to fish or reach their traplines. Because of that, some people lost their livelihoods altogether, they say.

Several of the First Nations and Mtispeopleaffected by the dam have already negotiated settlements with the province and Manitoba Hydro.But for the past nine years, trappingand fishinggroups from the OpaskwayakCree Nation have been trying negotiate their own compensation.

Those talks broke down around two weeks ago.

"We'll stay here as long as it takes to get Hydro at the negotiating table,"Morrisseau said.

Hydro responds

But a spokesperson for Manitoba Hydro said it was the trappers and fishermenwho walked away from the negotiating table in the first place.

"[Manitoba Hydro] is more than happy to talk to them but I want to be very, very clear that they were the ones who walked away from the negotiating table, not us," said Scott Powell.

"We've even offered to bring in a mediator at ourexpense to help with the discussions."

According to Powell, there's a dispute over how many fishers and trappers are eligible for compensation. Hydro is willing to compensate 59 fishers and more than150 trappers, based on how many were harvesting in the area at the time the dam was built, but the First Nations say hundreds more should be eligible.

CBC News has been trying to reach the heads of both the Opaskwayak Cree Nation Local Fur Council and the Opaskwayak Commercial Fishery Co-op for further comment, but cellphone coverage is poor in the area where the blockade is set up.

Powell confirmed that several trucks on contract with Manitoba Hydro that were headed to "points north"had been stopped and turned back by the blockade.

RCMP didn't respond to requests from CBC Newsfor information about the situation butCanada Carthage, a major trucking company, has beenwarning drivers and operators about the blockadeon social media.
