The drone-based GIS survey of all lakes in Karnataka is nearly complete. Latest data from the Karnataka Legislature reveals 37% of lakes are encroached. Bengaluru Urban (88%), Bengaluru Rural (90%), and Bengaluru South (57%) districts have the highest lake encroachment. Yadgir, Kalaburagi, and Udupi districts performed best. Mysuru, Mandya, Tumakuru, Davangere, Ballari, and Chikkamagaluru have nearly half of their lakes encroached. The Department of Survey Settlement and Land Records has identified 41,849 lakes over 7.78 lakh acres. Survey of 41,225 lakes is done, with 624 in Kolar and Hassan pending. Out of 41,225 lakes surveyed, 15,048 are encroached, covering 45,046 acres and 33 guntas. Commissioner J. Manjunath said the survey combined satellite images, drones, and ground rovers with digitised revenue maps to reach an accuracy of 5 centimetres. This is the first centralised database of all Karnataka lakes, helping unify data previously scattered across agencies. Bengaluru Urban has 837 lakes over 27,726 acres; 730 are encroached, affecting 4,229 acres (15.25%). Bengaluru Rural has 710 lakes over 30,032 acres; 643 are encroached, affecting 6,252 acres (20.8%). Bengaluru South records 57% encroachment but only on 5.24% of lake area. V. Ramprasad of Friends of Lakes said it is "heartening to see 107 lakes in Bengaluru Urban district to not have any encroachments." But he called the 90% encroachment in Bengaluru Rural "shocking," noting that growth is spreading the threat beyond the city. Minister for Minor Irrigation N.S. Boseraju said a state apex committee guides lake rejuvenation and clearing encroachments. District-level committees led by Deputy Commissioners handle local action. Departments updating encroachment clearances feed data into the centralised system. Friends of Lakes urges the government to make all lake data public to ensure accountability from authorities and encroachers alike.
