Puclaro Reservoir, Water reservoir in Coquimbo Region, Chile.

Puclaro Reservoir, officially named after Intendant Renán Fuentealba Moena, is a 200 hm³ artificial lake on the Elqui River, 50 km east of La Serena. Its 83-metre-high dam has a crest length of 595 m, and the water covers 760 ha with a maximum length of 7 km. The dark blue water is bordered by a strip of brownish sand and backed by barren brown and grey mountains.

Construction began in August 1996 over the sites of La Polvada, Punta Azul and Gualliguaica, and filling started on 15 October 1999 after the August 1997 storms disrupted the schedule. The dam, 83 m high with a 595 m crest, stores 200 hm³ and irrigates about 20,700 ha for 2,508 properties.

The reservoir's water is pure enough to be potable, and motorboats are banned, so the shores host windsurfing and kitesurfing schools. The irrigation it provides supports vineyards growing pisco grapes, table grapes for export and some wine grapes in the Elqui Valley.

The reservoir lies about 50 km east of La Serena in the Vicuña commune, reached by the road along the Elqui Valley. Motorboats are banned, so the water is used for sailing, windsurfing and kitesurfing; schools for these sports operate in the villages on its shores. The flooded area covers 760 ha and stretches 7 km, with the Gualliguaica and Marchigüe canal intakes submerged.

Strong winds at this water basin create excellent conditions for kitesurfing and windsurfing, drawing water sports enthusiasts to the area. Several schools and clubs have developed around the site to serve those seeking to practice these activities.
