The reservoir has a normal surface area of 1.6 square miles ( 4.1 square kilometres ), its length is 2.5 miles ( 4.0 kilometres ), its maximum width is 1 mile ( 1.6 kilometres ), and its maximum discharge is 28,954 cubic feet ( 819.9 cubic metres ) per second. Its normal storage capacity is 30,055 acre feet ( 37,072 megalitres ), and its drainage basin is 31 square miles ( 80 km ). It is the location of Guajataka Scout Reservation. Dam construction The construction of the dam was authorized by act 63 of the Legislature of Puerto Rico, known as the `` Isabella public irrigation law, '' approved April 19, 1919. The dam was constructed starting in 1928. The reservoir had an initial storage capacity of 48.46 Mm, or 48.46 × 10 ^ m ( 63.38 million cubic yards ), but by 1999 ( 71 years later ), the capacity had been reduced to 42.28 Mm or 42.28 gigalitres ( 55.30 million cubic yards ), as about 13 % less, attributed to sediment erosion. The surface area of the reservoir was 3.42 km ( 1.32 sq mi ) in 1999. According to the National Inventory of Dams, Guajataca Dam was designed by and is owned by the Puerto Rico Electric Power Authority. Guajataca dam failure risk This article needs to be updated.

( October 2017 ) On September 22, 2017, at 18 : 10 GMT, following Hurricane Maria, operators at Guajataca Dam announced that the dam 's spillway was failing at the northern end of the lake and it could result in the whole dam collapsing. The National Weather Service a few minutes later urged all 70,000 residents in the flood area to be evacuated. The National Weather Service stated the dam was a `` life - threatening situation ''. `` It 's a structural failure. I do n't have any more details, '' Governor Ricardo Rosselló stated. `` We 're trying to evacuate as many people as possible. '' Rosselló ordered the Puerto Rico National Guard and the Police to help assist in the evacuation effort downstream. The dam lies across the Guajataca River to form a reservoir that can hold roughly 11 billion gallons of water. As of September 2017, the dam was last inspected on October 23, 2013.
