<p>Considering the need of a lake for irrigation in parts of Mysore, King Mummadi Krishnaraja Wodeyar constructed a water body in 1864. This marked the origin of Mysore’s iconic Kukkarahalli Lake. The lake was spread over a vast area with feeder canals from all four directions. Feeder canals stretched as long as 25km, fetching rainwater to the lake from a much bigger catchment area.<br /><br /></p>.<p>The lake became a source of drinking water and irrigation. “Even industries got water supply from this lake,” informs, historian Nanjaraja Urs. With pristine water, clean environment and well-planned feeder canals, the lake became the princely state’s lifeline. Large number of migratory birds visited the lake every winter and made it a bird heaven. <br />Since 1900, water was supplied to Mysore, through pipelines. A check-dam built near Srirangapattana and Vani Vilas Water Works were the major sources of drinking water. Generation of Asia’s first Hydro-electric power in 1902 and <br />construction of Krishna Raja Sagara (KRS) Dam across River Cauvery are the major milestones in the history of Mysore. <br /><br />However, these two developments spelt doom for the Kukkarahalli Lake. Both <br />irrigation and drinking water needs of Mysore then had a bigger source. <br />Availability of electric power lead to efficient distribution of water. As a result, the lake lost its significance. As the city limits expanded, human settlements emerged in the catchment area. <br /><br />The tank bund became a dumping yard and sewage water was let into the lake. The lake was no longer serene and its neighbouring residents complained of foul smell. This lead to suggestions of closing the lake.<br /><br />Restoration efforts<br />For many Mysoreans, Kukkarahalli lake is not a mere water body. They have an emotional attachment to it, intimately woven with the cultural life of the princely state: This was a favourite place of legendary literary personalities like <br />Kuvempu, RK Narayan, Sarvapalli Radhakrishnan and TS Venkannayya.
