The Mactaquac Dam spillway, New Brunswick, on a foggy morning.

NB Power’s preferred Mactaquac Dam decision was handed down near Fredericton this morning. That decision is the late entrant among the options: to prolong the life of the dam as close to its original 100-year life as possible through maintenance and replacement in situ. Discussed today as the cheapest of the four options ($2.9 to $3.6 billion), the project has been given the oddly Soviet title of the Mactaquac Life Achievement Project. A new web experience awaits the curious who visit mactaquac.ca today, including backgrounders such as a paltry two-pager on First Nations engagement, the first output we have seen from that consultation other than this under-the-radar announcement via the NB Media Co-op. Kingsclear First Nation, whose land is a long sliver pointing directly at the dam, is deeply disappointed. Improvement is planned in multi-species fish passage, though not to the satisfaction of WWF, but the problem of inadequate upstream flow will still challenge any fish that survive the trip. No new river crossing for vehicles will be required, as the dam wall will continue to serve as a bridge. Many upriver locals will be pleased at this outcome, though expect frustration to be voiced at the the stress and disruption of the debate given such a status quo result. Let’s watch the budget evolve, and do it all again in a few decades. There is unlikely to be much money available to invest in renewables until then.
