Abstract: Recreational water use provides important benefits for human health; nevertheless, there can be adverse effects if the water is polluted. Aim of this work was to develop a Recre-ational Water Quality Index (RWQI) for Colina Lake in Mexico. Water samples were collected from March 2011 to February 2012 at seven random locations and at three depths (0.30 m, 1.0 m and 2.0 m). Parameters analyzed were pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), temperature (T), turbidity, total hardness (TH) chlo-rides (Cl-) and total (TC) and fecal coliforms (FC). Statistical analyses were made consider-ing a 12 ́ 3 factorial arrangement design while the RWQI was calculated for the 0.30 m depth. In general, results for parameters did not differ according to sampling depth or the interaction, but there were statistical differences according to sampling month. The RWQI indicates that water quality is generally adequate for recreational purposes
El uso recreativo del agua ofrece importantes beneficios para la salud humana; sin embar-go, al estar contaminada puede tener efectos adversos. El objetivo de este trabajo fue desa-rrollar un Índice de Calidad del Agua para Uso Recreativo (RWQI, por sus siglas en inglés) para el lago Colina en México. Las muestras de agua se colectaron de marzo 2011 a febrero 2012 en siete sitios al azar y a tres profundidades (0.30 m, 1.0 m y 2.0 m). Se analizaron pH, conductividad eléctrica (CE), sólidos totales disueltos (SDT), oxígeno disuelto (OD), tempe-ratura (T), turbidez, dureza total (DT), cloruros (Cl-) y coliformes totales (CT) y fecales (FC). Los análisis estadísticos se realizaron considerando un diseño de arreglo factorial 12 ́ 3. Los resultados presentaron diferencias estadísticas solo para los meses de muestreo, ya que no se presentó efecto de interacción. El RWQI se calculó para la profundidad de 0.30 m e indicó que la calidad del agua es adecuada para fines recreativos
