Blue Fish News – September 2020
In this September 3, 2020 issue of the Blue Fish Canada News we bust myths about dams and their fish passage systems; serve up a curated list of Links to fishing, fish health, water quality and other news; and end with an article on Newfoundland’s successful rebuilding of Atlantic Salmon numbers following the removal of a dam and a concerted long term recovery effort.
Dams and Fish Passage Systems
While most all dams pose barriers to fish mobility, not all rivers where dams are guilt are inhabited by migratory fish species. Further, dams equipped with fish passage systems don’t necessarily benefit non-migratory fish species. Compounding fish sustainability are reservoirs created by dams that don’t necessarily provide access to suitable spawning and rearing habitat, and the restrictions to fish mobility throughout watersheds that limit gene flow, resulting in unique and not always healthy genetic pools. The aging hydro dam on the St. Croix River in New Brunswick is one such dam that has caused all manner of fish sustainability issues for decades and is now about to be removed with the support of stakeholders including New Brunswick Power.
However, let us not forget the role dams can play in protecting and rebuilding native species like Alberta’s Cutthroat Trout from non-native migratory species like Rainbow Trout. Or how dams have prevented invasive Lamprey from moving beyond the great lakes. the paper mill dam in Georgetown Ontario on the Credit serves as an example of a structure being left in place on purpose to protect fish species introduced upstream, (Brown and Brook Trout), from having their habitat invaded by Rainbow Trout and Pacific salmon (Chinook and Coho) introduced into Lake Ontario in the 1970’s. Water exiting turbines can also serve as prime fish habitat that benefit both fish and anglers alike as they provide fish with a focussed source of food, and release the colder water located deep in reservoirs above dams that trout crave – a crucial habitat variable that is increasingly harder for fish to find as the climate continues to warm.
At the same time, thousands of abandoned commercial and private dams continue to carve watersheds into countless river-locked segments that serve no economic or practical purpose and remain largely forgotten. Professor Sean Landsman from Carleton University believes one of the main takeaways about dams and fishways is that there is hope for a better relationship between humans and migratory fish through increasing recognition that, “dam removal is warranted in many cases”, and “we are getting better at designing fish ladders and other fish passage systems that actually work”.
As humans continue to turn from carbon-based energy to electricity, the demand for hydropower will grow. The public, scientists, and perhaps most importantly, industry, recognize the need to ensure barriers to the movement of fish populations aren’t an unintended problem associated with newly constructed dams. But that doesn’t mean anglers can take for granted what’s happening at dams now.
The relationship between dams and fish is complex, which is why I asked Dr. Sean Landsman, a fellow angling nut, to help bring some clarity to a fish impact issue all of us anglers need to know. Dr. Sean Landsman is with the Institute of Environmental and Interdisciplinary Science at Carleton University.
In part one of this 2-part Blue Fish Radio series, Dr. Landsman discusses different dam configurations, movement of fish past dams in both directions, and why it makes sense to simply remove most smaller legacy dams.

Like me, many anglers may be of the mind-set that fish ladders or some other fish passage system introduced at dam sites is all that’s really needed. In this 2nd of my 2-part discussion with Dr. Sean Landsman, he explains the different fish passage systems adopted to move fish around dams, their strengths and weaknesses, and why alternative solutions to dams may be preferable in certain cases.

Job creation, infrastructure projects, economic recovery, will all become priorities as we dig our way out of the pandemic. The federal government recently announced a fund to clean-up abandoned oil drill sites in Alberta and Saskatchewan. Let’s hope that something similar is in the works specific to removing the tens-of-thousands of legacy dams throughout Canada. The window for these sorts of projects is relatively short because, once the economy is up-and-running, the equipment and human resources needed to do this work will be focussed on private sector developments. No one wants to see public resources used to bid against privately funded projects for access to such services and equipment. The time to make a difference is now, so let’s make sure we get the removal of legacy dams on the table for funding consideration.

Ontario’s Bill 197, COVID-19 Economic Recovery Act — Federation of Ontario Cottagers Association (FOCA)
FOCA is concerned that major changes to environmental oversight are underway, with the July 2020 introduction of the omnibus Bill 197, COVID-19 Economic Recovery Act, 2020. This Bill affects 43 different pieces of Provincial Legislation. FOCA believes that all environmentally significant undertakings should be reviewed through an appropriate and efficient EA process that is open, fair, and evidence-based. Further proposals to change the Planning Act would give Ministerial discretion to issue zoning orders, and to overrule decisions by municipal council and planning staff, even to the extent of a specific project and site details.

Newfoundland’s Rattling Brook Atlantic salmon Recovery Effort is Bearing Fruit!
(Notes from the Atlantic Salmon Federation Aug 28 2020)
The Rattling Brook watershed in central Newfoundland is small by the standard of other salmon rivers, but its 384 square kilometre (150 square mile) watershed includes some remarkably productive habitat
For example, an archaeological dig at the mouth of the river in 2005 uncovered artifacts from three waves of Indigenous settlement, one more than 5,000 years old. The lead archaeologist at the time proclaimed, “this site is probably the largest warm season salmon processing site in all of North America.”
Angling on Rattling Brook caught on in the early 20th century, but then salmon were completely blocked by the construction of a hydro dam with no fish passage in the 1950s.
Some Rattling Brook salmon were moved to the nearby Big Rattling Brook and other waterways. They established themselves, but the run on Rattling Brook was finished.
That’s until the nearby town of Norris Arm struck a committee in 1999 to investigate the possibility of a recovery program. Officials determined that restoration could provide $3 million in annual revenue to the community through a sustainable recreation fishery and the Rattling Brook Salmon Restoration Committee was born.
Starting in 2011, 50 adult salmon were captured from Big Rattling Brook, where the original Rattling Brook salmon were relocated, and placed back in their ancestral stream.
By 2013, Newfoundland Power, had completed their contribution to the project; a $5 million project to establish fish passage at the utility’s hydro dam on Rattling Brook.
Transplanting adults continued for four more season. When stocking was complete, 2,310 fish had been placed throughout the Rattling Brook watershed. With primary problems like fish passage addressed, the number of salmon returning kept increasing, hitting a milestone 1,000 and counting this year.
The perseverance of the Rattling Brook Salmon Restoration Committee, and the willing participation of partners like the Exploits River Environmental Resources Management Association, DFO, and NL Power are a model to follow.
Salmon conservation is a marathon, and Rattling Brook is proof that when the right decisions are made, wild Atlantic Salmon respond.
As for fishing in Newfoundland up to August 20th, most rivers in the province were experiencing very low water levels and very high-water temperatures. This led DFO to close most rivers throughout the Island portion of the province, and/or they restricted fishing to early morning outings only. The poor fishing conditions and river closures during the past two weeks meant very few anglers were fishing. For those who did fish, angling success was exceptionally low. But the Atlantic salmon were there, indicated by reports of many fish seen in the rivers on the island and at river mouths.
In Labrador, no rivers were closed for environmental reasons, although some probably should have been closed, given the low water conditions and warm water temperatures that were experienced in some areas. This was especially true in Southern Labrador.
Yet despite the hot and dry summer this year, Atlantic salmon have showed up in respectable numbers compared to recent years. It seems Atlantic salmon at sea experienced a better winter, with some combination of sufficient food supply, lower predation, and lower levels of fishing in Greenland waters.
