VISAKHAPATNAM: Water has been let out from the Meghadrigedda
reservoir for the first time during the current year after a gap of two
years.
With the onset of northeast monsoon, there is heavy rainfall in the
catchment areas. This has resulted in inflows reaching 5,000 cusecs.
The water level reached 59.9 feet on Sunday morning against a Full
Reservoir Level (FRL) of 61 feet. As a precautionary measure, irrigation
officials began releasing water from Saturday evening and on Sunday
four out of six sluice gates were lifted up to two feet releasing 4,900
cusecs. While all the six gates were lifted up to six feet in 2005 when
the reservoir reached FRL, releasing 53,000 cusecs, the reservoir came
to the full level again only in 2007. In 2009, it got filled only up to
58.5 ft. The Greater Visakha Municipal Corporation takes 10 MGD for
supply to Gajuwaka, Mindi, HSL Colony and some large industries around
that area.
The reservoir, renamed as Dronamraju Satyanarayana Reservoir, was
commissioned in December 1977. After the 2005 floods inundated the
Visakhapatnam airport stalling operations for 15 days, drain improvement
works were carried out to improve its carrying capacity to 63,000
cusecs. Water merges into the sea at Naval Dockyard marshy area. Large
number of people from all over the city thronged the reservoir to have a
look at the water gushing out of the sluice gates into the spillway.
Water collected from 135 sq. miles in Kothavalasa, Sabbavaram, Sonthyam
and surrounding hills get accumulated in the reservoir with 4.4 km of
flood bank and an earthen bund of 1.6 km and 240 feet of spillway.
