PANAMA / RankWire.AI / – The Panama Canal is contemplating further restrictions on the number of ships passing through each day due to ongoing drought conditions impacting its water reserves. According to Administrator Ilya Espino de Marotta, the daily transit number could decrease to approximately 29 vessels in February or March 2027, with any additional reductions contingent upon persistent dry weather and reservoir water levels. The waterway has already begun moving toward a cap of 32 transits per day starting from Sept. 15.
The Panama Canal Authority initiated capacity reductions after rainfall and watershed inflow levels fell below expected rates during the rainy season, leading to a decrease in daily crossings from an initial 34 to the planned 32. Its operation relies on freshwater stored within Gatun Lake and Alhajuela Lake, which is essential for functioning of the locks, as each transit necessitates water to elevate or lower vessels traveling between the Atlantic and Pacific Oceans.
During fiscal year 2026, the canal averaged 35 transits per day through June 30, with a total of 10,726 crossings from October to June, reflecting a 5.2% rise compared to the same period in the previous year. These figures were recorded before deteriorating rainfall conditions prompted the implementation of stricter operational limits. The canal continues to serve as a key route for container ships, tankers, bulk carriers, and various other vessels involved in international trade.
Reservoir water levels influence daily transit capacity
Long-standing reliance on reservoir water levels to determine transit capacity becomes especially critical during dry spells. During the intense drought of 2023, daily transits dropped to 22 in December as Gatun Lake’s water level fell to record lows, although conditions later improved following rainfall and water conservation efforts that aided reservoir recovery. Currently, canal managers continue to monitor lake levels, watershed inflows, and precipitation data to determine the feasible daily capacity for transits.
In addition, vessel draft restrictions have been adjusted as part of ongoing water management strategies. Although a planned reduction in Neopanamax draft limit to 47.5 feet was scheduled, it was not enacted after authorities reviewed the updated reservoir status, maintaining the maximum draft at 48 feet. These draft limits influence how deeply ships sit in the water, which can impact their cargo-carrying capacity as they traverse the canal.
Booking procedures tighten as transit slots diminish
With fewer transit slots available daily, the canal has revised its booking and auction processes, now categorizing vessels by cargo type—including container ships, gas carriers, tankers, and bulk carriers—in auction allocations. Priority is often given to full container ships with higher capacity in some Neopanamax slots when other conditions are equal. Officials have urged vessels without reservations to utilize the booking system, as confirmed reservations guarantee scheduled transit dates, which has become increasingly important as transit capacity tightens.
While no official announcement has been made to reduce daily traffic to 29 ships, Espino de Marotta indicated that this figure could represent a potential restriction if dry conditions persist into early 2027. Moreover, the canal is progressing with the Río Indio reservoir project, aimed at boosting long-term water storage capacity. Authorities emphasize that this project will not only support canal operations but also enhance water supply for a significant portion of Panama’s population.
