Dique Escaba is a reservoir built on the río Marapa in the southern part of Tucumán province, Argentina. The dam was constructed between 1937 and 1948 by Sollazzo Hnos S.A. and was designed by Ambursen Dam Co. It is a buttress-type concrete structure standing 83 meters high with a crest length of 232 meters, with the crest sitting at 636 meters above sea level. The reservoir covers approximately 500 hectares and is operated today by Hidroeléctrica Tucumán S.A. for hydroelectric generation.

The reservoir sits at roughly 127 kilometers from the provincial capital of San Miguel de Tucumán and 25 kilometers from the town of Juan Bautista Alberdi. Access is via Ruta Nacional 38 to Juan Bautista Alberdi, then Ruta Provincial 308 toward the dam. The first half of that provincial road, through the flatlands, is paved; the mountain section is gravel. Road conditions can be affected by heavy rainfall, which has caused landslides and temporary closures on the approach in the past.

The calm, flat water of the reservoir makes it well suited to kayaking and is appropriate for beginners. Kayak rentals are available in the vicinity of the dam, and a Club Náutico on the shoreline offers boat rental services. The surrounding landscape consists of mountains covered in yungas forest vegetation, giving the water a visually enclosed character.

Notable features in the area include a large bat colony estimated at over 10 million individuals that roost annually on the dam wall, a waterfall, and an old English Cemetery surrounded by araucaria trees. The surrounding terrain also offers hiking trails of varying difficulty. Mosquitoes are a practical concern in the area, and insect repellent is recommended.

Bus service connects San Miguel de Tucumán to Juan Bautista Alberdi, from which onward transport to the reservoir is possible, though schedules are limited. Accommodation options in the area include cabins and a hostería with restaurant service. Ente Autárquico Tucumán Turismo, the official tourism authority for Tucumán, lists the reservoir as a paddling destination and suggests a half-day as a typical visit duration.
