Bottom sediments in the reservoirs “La Fe, Riogrande II and Porce II” properties of EPM, were characterized for environmental quality through the determination of heavy metals (iron, manganese, lead and chromium), the content of bases (calcium, magnesium, sodium and potassium), the concentrations of total nitrogen (Kjeldahl) and phosphorus, sediment granulometry and mineralogy and the classification of diatoms. “La Fe” reservoir presents the best water quality (oligomesotrophic) compared to “Riogrande II” (mesotrophic-eutrophic) and “Porce II” (Eutrophic to hypertrophic); All three share similar characteristics in terms of total nitrogen (NTK) content which is in lower concentration relative to the total phosphorus (PT). The high abundance and occurrence of Spicaticribra kingstonii and D. stelligera in “La Fe”, Fragilaria familiaris and Discostella stelligera in “Riogrande II” and A. granulata in “Porce II”, were good indicators for the water quality at the reservoirs “La Fe” and “Riogrande II” and for the permanent eutrophy at “Porce II”.
