INFORME FINAL EVALUACIÓN REGIONAL DEL AGUA - ERA

The report details a comprehensive water assessment for the CORPOCHIVOR region in Colombia, employing the Water Evaluation and Planning (WEAP) system to analyze the Garagoa, Lengupá, Guavio, and Upía sub-basins. It establishes a baseline of water availability and demand, identifies critical micro-basins such as those in Úmbita and Ciénaga, and projects impacts under climate change scenarios to 2040. Key findings highlight a general lack of water retention capacity, deteriorating water quality in main river channels, and a discrepancy between official water concessions and potential actual demand in agricultural areas.

• The jurisdiction of CORPOCHIVOR exhibits a very low capacity for water retention and regulation. Out of the analyzed micro-basins, 196 are categorized as 'Muy Baja' (Very Low) and 5 as 'Baja' (Low) for the Water Retention and Regulation Index (IRH), a result primarily attributed to the steep relief of the region.
• Water quality in the main river channels is deteriorating over time. Analysis of monitoring stations with data since 2001 shows a downward trend in quality, with the river Garagoa specifically deteriorating from 'acceptable' in the upper basin to 'regular' and eventually 'bad' downstream.
• There is a significant discrepancy between officially registered water concessions and potential water demand, particularly in agricultural sectors. The report suggests that the corporation may be underestimating demand in agricultural micro-basins and that the current concessions database does not capture all users and extractions.
