[ edit ] Opponents to the 1977 Torrijos–Carter Treaties feared that efficiency and maintenance would suffer following the US withdrawal from the Panama Canal Zone; however, this has been proven not to be the case. In 2004, it was reported that canal operations, capitalizing on practices developed during the American administration, were improving under Panamanian control. Canal Waters Time (CWT), the average time it takes a vessel to navigate the canal, including waiting time, is a key measure of efficiency; in the first decade of the 2000s, it ranged between 20 and 30 hours, according to the ACP. The accident rate has also not changed appreciably in the past decade, varying between 10 and 30 accidents each year from about 14,000 total annual transits. An official accident is one in which a formal investigation is requested and conducted. Increasing volumes of imports from Asia, which previously landed on US West Coast ports, are now passing through the canal to the American East Coast. In 2007, the total number of ocean-going transits increased from 11,725 in 2003 to 13,233, falling to 12,855 in 2009. The canal's fiscal year runs from October to September. This has been coupled with a steady rise in average ship size and in the numbers of Panamax vessels passing through the canal. The total tonnage carried rose from 227.9 million PC/UMS tons in fiscal year 1999 to a then record high of 312.9 million tons in 2007, and falling to 299.1 million tons in 2009. Tonnage for fiscal 2013, 2014 and 2015 was 320.6, 326.8 and 340.8 million PC/UMS tons, carried on 13,660, 13,481 and 13,874 transits respectively.

In 1934, it was estimated that the maximum capacity of the canal would be around 80 million tons per year. In 2015, canal traffic reached 340.8 million tons of shipping. To increase capacity, a number of improvements have been made to maximize the use of the locking system: Implementation of an enhanced locks lighting system; Construction of two tie-up stations in Culebra Cut; Widening Culebra Cut from 192 to 218 m (630 to 715 ft); Improvements to the tugboat fleet; Implementation of the carousel lockage system in Gatun locks; Development of an improved vessel scheduling system; Deepening of Gatun Lake navigational channels from 10.4 to 11.3 m (34 to 37 ft) PLD; Modification of all locks structures to allow an additional draft of about 0.30 m (1 ft); Deepening of the Pacific and Atlantic entrances; Construction of a new spillway in Gatun, for flood control. These improvements enlarged the capacity from 300 million PCUMS in 2008, to 340 PCUMS in 2012. These improvements were started before the new locks project, and are complementary to it.

[ edit ] The water level at Gatún Lake from January 1965 to August 2024 Gatun Lake is filled with rainwater, and the lake accumulates excess water during wet months. For the old locks, water is lost to the oceans at a rate of 101,000 m 3 (26.7 million US gal; 81.9 acre⋅ft) per downward lock movement. The ship's submerged volume is not relevant to this amount of water. During the dry season , when there is less rainfall, there is also a shortage of water in Gatun Lake. As a signatory to the 2000 United Nations Global Compact and member of the World Business Council for Sustainable Development, the ACP developed an environmentally and socially sustainable program for expansion, which protects the aquatic and terrestrial resources of the canal watershed. The expansion uses three water-saving basins at each new lock, diminishing water loss. It also preserves freshwater resources along the waterway by reusing 60 percent of water from the basins in the locks in each transit. The mean sea level at the Pacific side is about 20 cm (8 in) higher than that of the Atlantic side due to differences in ocean conditions such as water density and weather. The 2015–2016 fiscal year was one of the driest periods on record, restricting ships passage. Temperature rise has also caused an increase in evaporation. In normal times, 36 ships can transit the canal each day, but in early December 2023, ships were backing up because only 22 ships per day could transit due to low water levels. In January 2024, 24 ships per day were allowed to transit. In 2025, the canal authorities begun plans to improve water levels in the canal by building a new dam to feed Lake Gatun, the fresh water source for canal operations. In 2026, the Panama Canal Authority reduced the number of ships per day because of lo

[ edit ] The Panama Canal, one of the most important chokepoints in global trade, has caused many environmental and ecological problems since it was built and expanded. These problems include deforestation , the spread of invasive species , water and air pollution, and water shortage. Deforestation in the Panama Canal drainage basin has been a problem for decades. In 1978, researchers said that "clearing the forest in the [drainage basin] might kill the canal." By 1985, the forested area had dropped to 30%. As of 2000, deforestation from human population growth, land degradation, and erosion continued to harm the ecosystem. Deforestation causes erosion, which raises the bottoms of the Gatún and Alajuela Lakes and lowers their ability to hold water. These lakes are very important for both canal operations and the local water supply. The Panama Canal has made it easier for invasive species to move between oceans. When the canal was expanded in 2016 with the third set of locks , global trade increased, and so did the spread of invasive species . These species cling to the ship and move from one place to another, something that without the boats they would not have been able to do. One example is the Asian green mussel , first found in Caribbean waters in the late 1990s, which has spread through the canal. These invasive species can harm local ecosystems and compete with native species. Ships passing through the canal regularly pollute the water. For example, in 1986, a crude oil spill east of the Caribbean entrance to the canal killed plants and invertebrates in the area. The shipping industry also releases emissions of greenhouse gases like carbon dioxide and methane . The Panama Canal, as a chokepoint, has a lot of heavy traffic and delays, which leads to burning more fu

[ edit ] In response to severe drought conditions that significantly impacted the Panama Canal's operations in 2023 and 2024, the Panama Canal Authority (ACP) announced plans to construct a 4600-hectare reservoir on the Indio River. The project aims to augment the canal's water supply and ensure consistent operations amid increasing climate variability. The reservoir, estimated to cost $1.6 billion, will include a dam and hold approximately 1.25 billion cubic meters of water. It is expected to provide water for up to 15 additional daily transits during the dry season and support over half of Panama's population with drinking water. This development followed a Panamanian Supreme Court decision in 2023 that redefined the legal boundaries of the canal’s watershed, enabling water projects like the Indio River reservoir to proceed beyond the traditional limits. The project has also raised social and environmental concerns, as it would displace an estimated 2,000 people and submerge local villages. By 2024, the ACP had begun public consultations to explore mitigation strategies and compensation plans for affected communities. As of March 2026, relocations of affected families was to start in 2027; construction was expected to begin in 2028 and complete by 2031.
