At a basic level, it is typically calculated in metres using the formula: [1] UKC = Charted Depth − Draft-/+ Height of Tide. Ship masters and deck officers can obtain the depth of water from Electronic navigational charts. [5] More dynamic or advanced calculations include safety margins for manoeuvring effects and squat.

The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around the southernmost tip of South America via the Drake Passage, the Strait of Magellan or the Beagle Channel. It is ...
Gatun Lake (Spanish: Lago Gatún) is a freshwater artificial lake to the south of Colón, Panama. At approximately 26 m (85 ft) above sea level, it forms a major part of the Panama Canal, carrying ships 33 km (21 mi) of their transit across the Isthmus of Panama. It was created June 27, 1913 when the gates of the spillway at Gatun Dam were ...
But insufficient rainfall continues to negatively impact the Gatun Lake, which feeds the canal, lowering its water level to 24.2 meters (79.7 feet), versus 26.6 meters (87.41 feet) for the month ...
During the 20th century, U.S.-Panama tensions worsened and there were growing protests against U.S. control of the canal, notably after the Suez Canal crisis in 1956, when British and French plans ...
The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the underside of the bridge at the chart datum Mean High Water (MHW), [3] [4] a less restrictive clearance than Mean Higher High Water ...
The Panama Canal will extend restrictions on ships' maximum depth, it said on Tuesday, and it has limited average crossings at one of the world's busiest trade passages to just 32 ships a day as a ...
Madden Dam, completed in 1935, impounds the Chagres River in Panama to form Lake Alajuela, a reservoir that is an essential part of the Panama Canal watershed. The lake has a maximum level of 250 feet (76 m) above sea level. It can store one third of the canal's annual water requirements for the operation of the locks.
