Wendover’s Panama Canal Explainer Leaves the Human Cost of Its Water Fix Off the Map

Wendover Productions' 2019 video explains the Panama Canal as an impressive piece of engineering. It shows how locks lift enormous ships, how tolls influence shipping routes, and how drought threatens international trade.

But when the video reaches the water crisis, its explanation becomes remarkably thin. It mentions that “there are also potential plans to build an additional upstream dam to create an additional reservoir” and moves on.

That missing detail matters. A major reservoir proposal already existed in the Río Indio basin. Its modern successor is a $1.5 billion project that would inundate thousands of hectares, displace farming communities and require the relocation of community cemeteries.

The video explains why the world needs the canal. It does not adequately explain what Panama may have to do to keep it running.

The reservoir was already more than a hypothetical

The video was published on July 2, 2019. The Panama Canal Authority's own archived records show that a multipurpose reservoir in the Río Indio basin was already being investigated during the 2017–2020 study period.

The Authority records that community meetings began on June 27, presenting the proposed reservoir's conceptual design, location, dimensions, potential construction methods and communities that could be partially or entirely affected. An environmental impact assessment process was also underway.

Just seven days after Wendover published its video, La Prensa reported that the Río Indio reservoir's technical study was approximately 70% complete and its social and environmental assessment approximately 50% complete. More than 55 communities had been informed about the feasibility studies.

The project was expected to require the relocation of affected residents.

There is an important qualification: the Canal Authority had not yet made a final decision to build the reservoir. It was still studying feasibility, costs and social and environmental consequences.

But that is precisely why the distinction matters. This was not an imaginary dam somewhere in Panama's future. It was an identifiable infrastructure proposal with an ongoing technical investigation and an emerging resettlement problem.

Wendover could have named Río Indio and explained the consequences of creating another artificial lake. Instead, it reduced the issue to an anonymous engineering solution.

The water belongs to more than the shipping industry

The video's treatment of water shortages also misses an essential part of the canal's institutional role.

The lakes supplying the Panama Canal also provide drinking water for approximately 2.5 million people, concentrated in Panama, Colón and Panama Oeste.

This is not simply a shipping company competing with another shipping company for water. It is a national water-management problem.

The Panama Canal Authority's 2024 Annual Report records that rainfall was 20% below its historical average. Total water inflows represented the driest conditions recorded in its 1898–2024 historical series.

Its water-use accounting recorded:

• 2,015 million cubic metres for lock operations and salinity-mitigation outflows.
• 542 million cubic metres for drinking water.
• 290 million cubic metres saved through water-conservation measures in the original locks.

These figures represent different allocations of the watershed's water, not proof that every cubic metre used by the locks was irretrievably lost.

The 2023–2024 drought also provides an important counterargument to any suggestion that the Canal simply prioritizes ships over people.

The Authority reduced daily transits from the normal 36–38 to approximately 22–26 between October 2023 and March 2024. It reported maintaining 427 million gallons of raw water daily for drinking-water treatment while reducing shipping activity to protect public supply.

That was a substantial economic sacrifice for the canal.

The problem has not disappeared. In September 2026, reduced rainfall again forced restrictions on daily transit capacity. Conditions subsequently improved enough for the Authority to restore one Neopanamax transit slot from October 15, although it reported that the watershed's water deficit remained.

A September 2025 study published in Geophysical Research Letters also projected substantially lower minimum annual Gatun Lake levels under higher-emissions climate scenarios, primarily because of reduced wet-season rainfall. The researchers acknowledged uncertainty in the magnitude of future drying.

The video's central warning about water availability was therefore justified.

Its weakness is that it never develops the more important question: how should Panama obtain additional water while protecting the people and environments affected by the infrastructure?

Río Indio: the human cost of the proposed solution

The current Río Indio project is considerably more substantial than the vague upstream dam mentioned in the video.

The Canal Authority's plans involve:

• An estimated investment of $1.5 billion.
• An artificial lake covering approximately 4,600 hectares.
• Storage capacity of approximately 1.294 billion cubic metres.
• A tunnel approximately nine kilometres long to transfer water by gravity into Gatun Lake.
• A main dam and three auxiliary dams.

The Authority says the reservoir will strengthen drinking-water security for more than half the country's population while supporting the Panama Canal's operations.

It is also expected to support the equivalent of approximately 10–15 additional daily canal transits.

There is a genuine national benefit here. Panama needs additional water infrastructure, and the reservoir would provide substantial storage capacity.

But the reservoir's footprint is not empty land.

According to reporting by Mongabay citing the Canal Authority, approximately 38 farming communities and 2,000 residents would be affected.

There is also an unresolved discrepancy in published resettlement figures. An Infobae report in May 2026 identified 423 families within the project area, while La Prensa reported 550 families across 38 communities in September. The reports do not explain whether the difference reflects an updated count or different definitions of the affected population.

These are not interchangeable numbers. The Authority should publish a clear reconciliation.

The affected communities depend heavily on agriculture and livestock. For many households, their land is not merely a financial asset. It is their livelihood, their family history and their connection to the surrounding community.

Alexandrina Muñoz, a farmer from Limón de Chagres, told Mongabay:

“We don’t have any opportunity; we only have our lands. Where shall we go?”

This is the human dimension missing from the video's explanation of water infrastructure.

There is another uncomfortable detail. The Canal Authority's own Río Indio project website identifies inadequate local drinking-water infrastructure as one of the principal social problems affecting communities in the basin.

It separately proposes improvements to rural water systems, sanitation and community infrastructure.

In other words, communities living in the very watershed being developed to strengthen national water security still need better local water services.

The reservoir may benefit millions of Panamanians. That does not make the distribution of its benefits and costs an automatic success.

The displacement is already affecting community life

The consequences are no longer confined to engineering drawings and future construction schedules.

On July 21, 2026, Panama's government issued Executive Decree No. 26 establishing deadlines for ending new burials at eight community cemeteries located within the future reservoir area.

The cemetery at El Limón stopped accepting new burials on July 30. Seven additional cemeteries are scheduled to stop accepting new burials by January 15, 2027.

The decree also authorizes the exceptional exhumation and relocation of remains under specified conditions, including the approval of regional health authorities.

The authorities are responsible for the costs of transferring remains, providing coffins or urns, arranging new burials and replacing tombstones or mausoleums.

These arrangements matter. Cemeteries are not ordinary infrastructure. They preserve family histories, religious traditions and community identities.

A reservoir can replace a road, construct a new house and compensate someone for lost agricultural production. Replacing the relationship between a community and its burial grounds is considerably more complicated.

The fact that these arrangements are already necessary, before the main construction work begins, gives a much clearer picture of what the project means locally.

TVN's reporting on the cemetery relocation decree documents the deadlines and conditions governing the process.

Consultation is not the same as agreement

The Canal Authority has not simply ignored the affected population.

It reports completing more than 200 meetings during seven rounds of dialogue between May 2025 and February 2026. These included more than 60 community meetings and 150 individual meetings.

Its compensation framework includes replacement housing, land, compensation for crops and livestock, lost economic income and psychosocial support.

The Authority says it intends to keep replacement communities close to their existing surroundings, preserving family networks and economic activities where possible.

By September 2026, the project had entered individual compensation negotiations, with the Authority assessing the value of affected properties and livelihoods.

These are meaningful steps, and they deserve recognition.

However, participation in meetings is not the same thing as agreement to leave one's home.

On September 26, 2026, more than 500 people reportedly participated in a peaceful protest representing ten communities. Community representatives said residents had not agreed to abandon their land and questioned why relocation negotiations were progressing.

That does not establish that every affected family opposes the project. Nor does it establish that the compensation arrangements are inadequate.

It establishes that the process remains contested.

The distinction matters because successful resettlement cannot be measured simply by counting meetings, distributing compensation or constructing replacement houses.

The Canal's own deputy administrator has said that the resettlement and livelihood-restoration process will continue beyond 2034, with support intended to last until families have recovered their livelihoods.

That is a remarkable admission of the scale of the undertaking. Moving families is a construction milestone. Restoring their lives is a much longer obligation.

Is Río Indio the only answer?

There is another question the video never explores: whether the proposed reservoir is the best available solution.

The Canal Authority says it has evaluated more than 28 alternatives over approximately 30 years and considers Río Indio the most viable option.

However, the Panamanian Society of Engineers and Architects (SPIA) has argued that Río Indio should not be treated as the only possible solution.

Following its July 2025 technical forum, the professional association called for a more rigorous comparison of alternatives involving independent experts.

One alternative discussed is the use of water resources associated with the existing Bayano reservoir.

The Canal Authority argues that Bayano presents greater technical and economic difficulties because of its distance from the canal lakes and the infrastructure and pumping requirements involved.

The disagreement does not establish that Bayano is superior. It does establish that the choice deserves transparent technical scrutiny.

A $1.5 billion reservoir involving the relocation of hundreds of families should not be treated as inevitable merely because additional water storage is necessary.

The public deserves to understand which alternatives were evaluated, what they cost, how much water they can reliably supply, and why the selected option offers the best overall outcome.

The verdict: a canal is more than a shipping machine

Wendover's video gets much of the engineering and shipping economics right. The Panama Canal is an extraordinary piece of infrastructure, and the threat posed by declining water availability is real.

I am not arguing that Panama should refuse to build additional water infrastructure. Millions of people depend on the same reservoirs that sustain international shipping, and the 2023–2024 restrictions demonstrated the economic consequences of inadequate water storage.

But a serious explanation of the canal's future must go beyond the movement of ships.

The Río Indio project connects international trade, national drinking-water security, rural livelihoods, land ownership, environmental protection and the relocation of communities.

It involves hundreds of families, eight cemeteries, contested alternatives and a compensation programme that could continue beyond 2034.

None of these details requires accusing the Canal Authority of wrongdoing. They require asking whether the costs are properly understood, whether alternatives have been fairly assessed, and whether the people affected will genuinely recover what they lose.

Wendover tells us why the world needs the Panama Canal.

It leaves out the people whose homes, farms and burial grounds may have to move to keep that shortcut operating.

That is the missing story.
