All efforts by SOM to find out the basis on which the water level of reservoirs are measured from the engineers at the Kabini dam proved futile.
When asked the water level at Kabini dam, the engineer said it was 2284 ft. This left SOM wondering whether the water level at Kabini is much higher than that of KRS which is a bigger dam with a maximum water level of 124.80 ft.
However, M. Lakshmana, the Convener of the Association of Concerned and Informed Citizens of Mysore (ACICM), when contacted in this regard, explained that except KRS reservoir, the heights of all other dams are measured on the basis of Mean Sea Level (MSL). He said that the Kabini dam is at 2210 ft. above sea level and the dam’s water level is 74 feet. Hence the total height is recorded as 2284 ft.
Lakshmana also said that the silt deposit in KRS reservoir is as low as 0.5 feet because the dam’s base is hard rock strata, unlike other dams which is muddy, as per a report submitted by Karnataka Energy Research Station (KERS) to the State government during May 2013.
