Abstract
Matatilla reservoir, located in semi" arid region, (Lat 25° 15' N and Long. 78° 23'E) has
an area (at FRL) of 13,893 ha, volume and shore development 0.663 and 1.65, shoreline 73.6
km. Volume and shore development indicate that greater pmi of the reservoir is shallow,
which is a favourable point for fish productivity. Temperature and dissolved oxygen gradually
decreased with the increase in depth. Carbon dioxide was absent from the surface but
invaRiably present in the bottom (3.6 ppm). pH remained alkaline (7.2-8.4 ppm) throughout
the year. Alkalinity, chlmide, calcium, magnesium, hardness and productivity was maximum
in premonsoon and minimum in monsoon except for calcium and magnesium in postmonsoon.
Phosphate, nitrogen and ammonical nitrogen were found in traces. These variations may be
due to influx and outflow of water and use of reservoir water for multipurpose activities.
