Ellen Reynolds
Recommendation for course of action with Montgomery Dam
10 December 2024
Recommendation: Full removal of Montgomery Dam and return to the natural channel. Working in partnership with the Library Board of Trustees to incorporate the river into harbor park in a manner that aligns with the Olmstead vision, while simultaneously creating a more resilient shoreline with greater access to the water.
Justification:
Historical
We have considered the watershed from a historical vantage point and accumulated a collection of varying thoughts on the subject. While some feel it is paramount to honor the industrial history of our community, others prefer the scope of native or natural history. As a scientist, I am inclined toward the natural history of the watershed wherever we are able. I do believe there is something magical in maintaining landmarks of our human story and find efforts in preservation to be generally worthwhile. In this case, although I find the history of the dam to be interesting and compelling, I consider its negative impacts to outweigh its historical value. As a relic dam, no longer serving a utilitarian purpose, it marks a beautiful piece of history at the detriment to the health and wellbeing of the watershed ecosystem.
Removal of the dam and a return to the natural path can more adequately honor the river’s natural history. Paired with adequate signage, river walks, and teaching opportunities, removal of the dam can continue to honor the industrial history of Camden and assure that the story of our past is not removed from our collective conscience.
Ecosystem Connectivity
While some consider the river to be healthy enough in its current state, evidence indicates that dams significantly disrupt ecosystem connectivity by creating literal barriers and dividers within the natural habitat. Whether it is in a river system like our own or on land, fragmented habitats are known to be detrimental to the overall health of the system. Across the country and around the globe, environmental groups, state and federal agencies are working to create contiguous habitats in an effort to restore resilient species populations, reducing isolated segmentation and increasing genetic diversity within the ecosystem.
The removal of dams is additionally known to impact water flow patterns, resulting in improved nutrient and thermal distributions, creating a more hospitable habitat for organisms to survive and thrive.
In my ideal world, the removal of Montgomery Dam would be passed, and swiftly followed with the removal of the Knox and Knowlton Street dams to positively impact the ecosystem to the greatest extent possible.
Flooding
As it has been stated in numerous discussions, the Montgomery Dam does not provide flood mitigation, and instead poses increased risk over a free-flowing river. This is especially true for the buildings surrounding the impoundment who stand a greater flood risk with immediate proximity beside or above the impounded water. While dam removal does not mitigate the risk of downtown Camden flooding entirely, it does reduce the risk and diminishes the potential flood zone in size.
While the flood models clearly show this positive impact of dam removal, they do not take into account the additional damage and flooding possibilities from debris or other items getting caught in the dam, potentially exacerbating the issues of flooding further. For this reason, the flood models showing the impacts of the dam seem conservative in their flood risk projections if anything.
As rain events increase in frequency, severity, and unpredictability, I believe our best course of action is to prepare for those changes and buffer our community against potential damages whenever and wherever we are able.
Financial
As we all know, there is no option available that does not have a significant associated cost. From a financial perspective, removal of Montgomery Dam far outweighs the other options available. In every option, there is a substantial capital investment that cannot be ignored, but full removal of the dam would result in significantly lower ongoing maintenance and management costs. This choice allows us to remove the future financial burden from the shoulders of our children. When there is no dam to manage, there is no cost to manage it. Alternately, maintaining a relic dam for the sake of historical preservation or subjective aesthetics requires ongoing maintenance and repair costs without end.
The removal of Montgomery Dam additionally opens the doors to federal funding in a manner that significantly decreases the burden of cost to the local community. Showing state and federal agencies that we care about ecosystem connectivity and habitat restoration for sea-run fish opens the door to financial assistance at a magnitude that is irresponsible to turn down. Not only can funds be utilized for dam removal, but they can additionally help us to manage other issues upstream that will otherwise cause additional tax burdens to the community. The compounding cost of dam management for all town-owned dams is significant and ongoing, and can be greatly reduced with federal assistance.
Financial, Part II
It has been proposed on more than one occasion that removing Montgomery Dam will have a negative economic impact on downtown businesses. This idea is often bolstered by perceptions that the dam is the crowned jewel of our community. Unfortunately, there has not been evidence to support this thought, and I believe it to be speculative at best. In fact, keyword searches for tourism in Camden indicate that the dam is not amongst the most commonly highlighted experiences. Instead, visitors make frequent note of the wooden ships, the shops and restaurants of downtown, our hiking trails, state park, library, opera house, and church steeple. It is my personal belief that, based on this information, Camden will continue to thrive as a beautiful place to visit regardless of the dam’s presence or lack thereof.
It is additionally the case that removal of Montgomery Dam creates a gateway to new potential experiences that may well bolster the town’s economic wellbeing. A free-flowing river, returned to its natural path, can allow greater access and integration into our daily lives. Paired with a re-imagined seawall, the experience of harbor park could be one that includes both land and water, as a seamless and integrated landscape to be utilized. Lower river levels along the impoundment open the potential for innovative concepts like river-walks and educational access points. All of this to say that there simply is not evidence that removing Montgomery Dam will negatively impact the economic wellbeing of this community, and with a little imagination and creativity, it has the potential to do quite the opposite.
Finally, there is a real potential economic benefit made available by the presence of a large and healthy alewife population, that can be considered for harvesting should the community choose to do so, creating a sustainable revenue stream for years to come.
Fish Passage
The discussion around fish passage has gone in circles to near exhaustion, and there will be some who will remain determined that sea-run fish never traversed these waters. There are others, of course, who simply don’t care, and I honor that. If it isn’t important to you, it doesn’t have to be. That said, there is consensus amongst experts that Megunticook River was historically home to sea-run fish and is able to return to that natural state with our assistance. The return of alewives to our river ecosystem would result in significantly improved health and resilience of the watershed, and they are only one species that we have the potential to see return. There has been the question of increased seagulls and the concern that they would be a nuisance. But let me remind you that a river that supports sea-run fish, and alewives in particular (who are identified and known to be a keystone species), provides nutrient rich waters in support of a long list of species who all benefit greatly from a healthy ecosystem. So, while there may be more seagulls, we can also realistically anticipate more of the species we have subjectively determined to be more beautiful or worthwhile. More ospreys, more eagles, more cormorants and herons and terns. More cod in the harbor, more whales and seals and otters in their pursuit.
As a fisheries biologist, I have observed and recorded the decline of species and species habitat for decades. Returning a river to its natural flow and reintroducing the ability for sea-run fish passage is a uniquely rare gift to improve the wellbeing of our environment, and consequently our planet. While it may mean nothing to some, it genuinely means everything to others.
General Ethics
When I personally look at the deliberations around whether to keep or remove the Montgomery Dam, I often feel that it boils down to two very different outlooks on life. The idea of keeping a dam that is no longer functional and has been identified as an impediment to the wellbeing of the river system it once relied on, reads to me as a human-centric viewpoint. Do I honor our industrial history? Absolutely, and I believe we should continue to keep it alive in all of the reasonable ways that we are able. I am additionally sensitive to the fears that change brings, the worry around the unknowns, and the stress that abutting business owners have shared. We are not necessarily adept at embracing change, and often feel that remaining in the comfort of what we have always done is safer and easier. This is a consistent human experience that I am not a stranger to, but I do not believe it should be paramount in guiding us.
On the other hand, the idea of removing Montgomery Dam to aide in returning the river to its natural flow; to improve habitat connectivity; to reintroduce a healthy sea-run fish population; to reduce the risk of flooding along what is now a heavily inhabited watershed; and to diminish the ongoing costs for generations to come feels like a proactive, sustainable, earth centric approach—one that benefits numerous species, including ourselves. It is my perception that we are faced with an opportunity to sacrifice a little bit of what we personally love to benefit the well-being of our community on a much greater scale. I believe it is our ethical responsibility to move forward with removing Montgomery Dam.
