Summary and Conclusion SUMMARY AND CONCLUSION Since the dawn of civilization, water has been the most important raw material for civilization. It is one of the vital sources of all kinds of life on the earth. Economically, culturally and biologically water is most useful natural resource on the earth. We use water for drinking, bathing, cooking, cooling, irrigation, transportation, energy power and recreation. Thus, water is nature's gift to the living world including human race. Our biosphere consists of 71 % of water out of which fresh water environment occupied only 2.6 %. For the usable purpose only 0.62 % water from lakes, streams, rivers and other resources are available for the living organisms. In India most of the cities, towns, villages and industries are situated at the bank of rivers and lakes. Due to uncontrolled population, the huge quantity of untreated sewage is being added everyday in these different water reservoirs. Besides these, industrial wastes, residues of insecticides, pesticides, excess agricultural fertilizers also added in these fresh water eco-systems causing pollution and creates health hazards. Present study is on the taxonomic data of algal specieswere collected from Station SI: Dimbhe Dam, It is located on Ghod River at Dimbhe 11 kms away from Ghodegaon in Ambegaon Tehsil. Station S2: Manikdoh Dam, It is located on Kukadi River at Manikdoh 7 kms away from Junnar in Junnar Tehsil. Station S3: Pimpalgaon Joge Dam, It is located on Pushpavati (Aar) River near Joge, at Nagar-Kalyan Highway in Junnar Tehsil. Station S4: Wadaj Dam, It is located on Meena River at Wadaj 5 kms away from Junnar in Junnar Tehsil Station S5: Yedgaon Dam, It is located on Kukadi River at Yeadgaon 10 kms away from Alephata in Junnar Tehsil. Water samples were collected periodically from above five sampling stations. For qualitative analysis, water samples were collected separately in the bottles. Collections were done from streams, rivers, ponds, puddles, and impoundments 304 during and after monsoon season from Junnar and Ambegaon Tehsils of Pune District. Algae of different habitats were collected from these localities such as - planktonic, benthic, epiphytic, terrestrial, epiphyllous and from tree-trunk. Planktonic algal collection was made by using plankton net of bloting silk cloth 25 meshes/linear inch and analyzed qualitatively. Phytoplanktons were collected by using phytoplankton net from surface waters of impoundments. Quantitative estimation was done for phytoplankton by Lackey's drop method (Lackey, 1938). Algal identification was carried out by using standard literature and monographs. Microphotographs of algal plants encountered during investigation period were taken. I have collected 552 algal specimens. These are from 17 orders of 3 classes and 5 divisions. In which 445 planktonic, 82 benthic and 25 epiphytic specimens were collected. I investigated 5 impoundments out of this Manikdoh Dam shows more diversity of algal plants. Whether Pimpalgaon Joge Dam shows less number of algal plant, station wise algal Diversity as below. Station SI: Dimbhe Dam shows presence of 334 species from 10 orders, out of which order Pinnales shows rich diversity in this station while order Chrysomonadales shows less diversity of algal species. Station S2: Manikdoh Dam shows presence of 338 species from 11 orders, out of which order Pinnales shows rich diversity in this station while order Tetrasporales shows less diversity of algal species. Station S3: Pimpalgaon Joge Dam shows presence of 286 species from 11 orders, out of which order Chlorococcales shows rich diversity in this station while order Tetrasporales and order Chrysomonadales shows less diversity of algal species. Station S4: Wadaj Dam shows presence of 337 species from 11 orders, out of which order Pinnales shows rich diversity in this station while order Tetrasporales shows less diversity of algal species. Station S5: Yedgaon Dam shows presence of 314 species from 10 orders, out of which order Pinnales shows rich diversity in this station while order Chrysomonadales shows less diversity of algal species. 305 The present investigation shows 17 orders, 47 families, 136 genus, 436 species, 105 varieties and 11 forma from 5 divisions and 3 classes. Present investigation shows dominance of Chlorophyta over Cyanophyta, Chrysophyta, Pirrophyta and Rhodophyta. Chlorophyta is represented by 186 species while cyanophyta by 146 species. Conclusions: This research work helps us to know type of algal flora of the study area. The data gathered serves as base line data for planning utilization and conservation strategies of algae. Phytoplankton studies helps us to know primary producers (Qualitatively and quantitatively) of the study area. This research work may help all the phycological students to study the algal vegetation in Junnar and Ambegaon. In this study area Manikdoh Dam shows more algal diversity which followed by Wadaj Dam, Dimbhe Dam, Yedgaon Dam and lastly Pimpalgaon Joge Dam shows less algal diversity. 306 .

  • Sustainable Development of Irrigation in Kukadi Integrated Project by Transfer of Surplus Water from One Reservoir to Other
    Sustainable Irrigation and Drainage IV 403 Sustainable development of irrigation in Kukadi integrated project by transfer of surplus water from one reservoir to other U. V. Siddamal & C. A. Birajdar Water Resources Department, Govt. of Maharashtra, India Abstract An integrated Kukadi irrigation project in western ghat of Maharashtra state in India comprises of five dams built on the Kukadi River and its tributaries receiving seasonal rains. The water from four reservoirs namely Dimbhe, Manikdoh, Wadaj and Pimpalgaon Joge is fed to Yedgaon reservoir through canal and river. The command area of the Kukadi integrated system downstream of Yedgaon dam extends over three districts. The total irrigable command area under the entire Kukadi project is 156278 Ha. The irrigation requirement of the command area is increasing with completion of the canal system over a period of time. Thus storage in all five reservoirs is to be optimized to its full capacities by the end of monsoon following the approved reservoir operation schedule, to meet irrigation and drinking water requirements of the project for complete water year. In the Kukadi integrated project the works of five dams namely Yedgaon (1976), Wadaj (1975), Manikdoh (1986) Pimpalgaon Joge (1999) and Dimbhe (2001) are completed. The Reservoir has received a yield of more than 75% dependable yield only twice during the last 25 years since its completion. An integrated project comprising of five reservoirs is being severely affected due to less rains than estimated in the Manikdoh catchment area. Due to this fact the storage capacity of Manikdoh reservoir is underutilized and adversely affected the performance of the integrated Kukadi project, ultimately resulting in a great stress on the minds of management engineers to fulfill the targets with limited water resources.

ABSTRACT An integrated Kukadi irrigation project in western ghat of Maharashtra state in India comprises of five dams built the Kukadi River and its tributaries receiving seasonal rains. The water from four reservoirs namely Dimbhe, Manikdoh, Wadaj and Pimpalgaon Joge is fed to Yedgaon reservoir through canal and river. In the Kukadi integrated project the works of five dams namely Yedgaon dam, Wadaj dam , Manikdoh dam , Pimpalgaon Joge dam and Dimbhe dam are completed. The Reservoir has received a yield of more than 75% dependable yield only twice during the last 25 years since its completion. We are study the “Manikdoh Dam” among this dam. Thus storage of this reservoir is to be optimized to its full capacities by the end of monsoon approved reservoir operation schedule, to meet irrigation and drinking water requirements of the project for complete water year. An integrated project comprising of five reservoirs is being severely affected due to less rains than estimated in the Manikdoh catchment area. Due to this fact the storage capacity of Manikdoh reservoir is underutilized and adversely affected the performance of the integrated Kukadi project, ultimately resulting in a great stress on the minds of management engineers to fulfill the targets with limited water resources.
