Abstract

Visnagar city is located in north Gujarat (72 30 n and 73 30 n 23 0 e and 23 35 e). Visnagar taluka is popularly known as ‘Shikshan Nagari’ and also known as Copper city. The climate of visnagar is tropical arid to marginal semi-arid. It is strongly periodic and seasonal. There are many fresh water bodies are situated at and arou Deliya lake is natural fresh water body having 19 hector area & circular in shape. It is located between latitude230 41’ 60’’N longitude720 32’ 60’’ E. it is oldest lake of visnagar. It is also known as hanuman temple talav. Constructed before 10’th century.nd Visnagar taluka. The present study deals with the physico-chemical status of deliya lake. This water bodies has dense growth of algae and planktons in its. Physico-chemical status of lakes belongs to Visnagar Taluka were studied in year 2011. The physico- chemical parameters show pH, Dissolve Oxygen, totol dissolved Solid, E.C., Chloride, Alkalinity, Total Hardness, Calcium, Calcium Hardness, Magnesium, Magnesium Hardness, Fluoride, Nitrate, COD, BOD, etc and water is essential for living organisms especially like flora and fauna observed through various field trips. Showing abundance of analytic species and spirulina species with many other members of chlorophyceae. Euglenophyceae, Bacillariophyceae and cyanophyceae, microbiological analysis shows positive results for E.Coli, Vibro sp. and many other pathogenic. An isolated area of the lake is totally infested with eicchornia Spe. The migratory and local bird like plegadis falcinellus, Ardea parpurea, Egretta intermediate. Ardeola grayli, Dendrocygna, jaranica (and many more have been observed). If the sewage and other waste are diverted to some appropriate area other than the lake water quality and ecology of the pond can be restored and will be used in drinking and agriculture by the people.
