Thin on the right so far

Only 2 of the 15 outlets with a published leaning rating that ran this story are rated right.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

The removal of the final dam on the Narraguagus River in Maine has opened up the waterway, creating prime habitat for endangered Atlantic salmon. Ellie Mason, a habitat restoration project manager, observed abundant prime habitat for the fish on the river. Despite these improvements, the return of wild adult salmon to the Narraguagus has been minimal in recent decades, with only about 25 individuals spawning annually.

Disagreement on Dam Removal

The Toronto Star, The Hamilton Spectator, Associated Press News, The Record, and The Maine Monitor state that Cherryfield rallied to remove the last dam on the Narraguagus River. The Maine Monitor adds that this occurred after decades of habitat rehabilitation by local conservationists and landowners. The Independent and The Independent (US) report that the dam removal is part of a habitat restoration project. The remaining digests do not specify how the dam was removed or who was involved.

What the coverage left out

None of the left-rated digests mention the specific number of wild adult salmon returning to spawn annually, stating only that the fish are missing or that only about 25 have returned in recent decades. The centre-rated digests also do not mention the specific number of wild adult salmon returning to spawn annually, only that about 25 have returned. The right-rated digests also do not mention the specific number of wild adult salmon returning to spawn annually, only that about 25 have returned.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

9 rated outlets

  • Nine left-rated digests reported on the reopening of the Narraguagus River for Atlantic salmon. These digests consistently mentioned Ellie Mason observing prime salmon habitat and noted that the Gulf of Maine's Atlantic salmon are endangered. They also highlighted the low number of wild adult salmon returning to spawn annually, approximately 25. Several left-rated digests, including The Toronto Star, The Hamilton Spectator, Associated Press News, The Record, and The Maine Monitor, specifically mentioned that Cherryfield rallied to remove the last dam on the river. The Maine Monitor also noted that this followed decades of habitat rehabilitation and that climate change poses a long-term challenge to the salmon's comeback.

They mentioned that the removal of the last dam on the Narraguagus River is a new development. PenBay Pilot noted that as climate change progresses, a comeback is not guaranteed.
