Quebrada Matamoros is an intermittent watercourse located in the Huasco Province of Chile's Atacama Region, situated north of the Quebrada Carrizal. Its intermittent nature is the defining characteristic, meaning it is not a permanently flowing river but a channel that carries water only during and immediately after periods of significant rainfall. This has a profound impact on the paddling experience, as the water body may be completely dry for extended periods. Specific access points for putting in or taking out are not detailed, nor are recommended routes, seasonal water temperature patterns, or water quality. There is no mention of facilities, amenities, or specific regulations for paddlers. The description does not describe notable sights, wildlife, or the overall aesthetic appearance of the landscape surrounding the quebrada. Due to its intermittent flow, planning a paddling trip requires careful consideration of recent and forecasted precipitation in this arid region. The best opportunity for paddling would be shortly after heavy rain events, but these are unpredictable. The lack of permanent water also suggests that hazards could include rapidly changing water levels, flash flooding, and potentially difficult or non-existent access to the channel bed when dry.
