Isapur water reservoir is an earth fill dam, located on Penganga river of Yavatmal district, Maharashtra state, India. The reservoir was constructed in 1982, with an aim to provide water for irrigation purpose. Yavatmal district is known for rock forms like shales, slates, sandstones and limestone etc. These rocks along with anthropogenic sources like industrial and agricultural runoff acts as important source for heavy metals in the surrounding areas.
Selenium is a naturally occurring bio-accumulative pollutant, nutritionally important in micro quantity, but at higher concentrations, can be lethal to all life forms. The separating line for selenium between dietary requirements and toxic concentration level is quite thin, so it has become an essential health concern. It enters in surface water through natural, anthropogenic activities, gets accumulated in tissues of aquatic plants and animals.
Selenium contamination in water and sediment was evaluated in the selected sampling locations during June, 2012 to May, 2013. Objectives behind these investigations were to determine the sources of selenium in the aquatic system of this reservoir and to aware the society from probable impacts of selenium ions of this aquatic body as well surrounding environment. Four water and two sediment sampling locations were selected at entry and exit points of dam, from which the samples were collected.
The maximum selenium level were observed during monsoon, 2012 (0.014 mg/L) and lowest during summer 2013 (0.012 mg/L). In case of sediment analysis the maximum and minimum selenium level noted were 19.0 and 9.0 mg/kg in monsoon and winter respectively
Selenium concentration was higher at sites where water is entering into the dam containing surface runoff, compare to other sites. Sediment and water analysis has proven that agricultural runoff and geological rocks may be the basic sources of selenium into the reservoir.

Key words: Reservoir Water, Selenium, Irrigation, Agricultural runoff, nutritionally important, Bio-accumulative pollutant.
