Assessment of limnological characteristics of a tropical reservoir

Abstract

Present study was carried out on Kanigiri reservoir, Nellore Dist., Andhra Pradesh for a period of eight months analyzing selected parameters at fortnightly intervals using standard methods. It is alkaliphilous (pH: 7.70 to 8.45), medium to high productive reservoir (TDS: 131.5 to 227.5 mg/L), experiencing moderate domestic pollution with chlorides (70-129 mg/L) and can promote the growth and survival of fish (D.O of 4.6 to 8.35 mg/L, CO2 of 0 to 6 mg/L &total ammonia of 0.02 to 0.21mg/L). Hence, it can be said that, water from this reservoir is fit for irrigation, agriculture, pisciculture, industrial, domestic purposes and with little treatment with respect to BOD and total hardness can even fit for drinking also.
