TELANGANA NAGARJUNASAGAR CREST GATES LIFTED TO RELEASE FLOOD WATER
Due to unprecedented heavy flood inflows from upstream reservoirs, officials in Telangana have lifted 22 crest gates at the Nagarjuna Sagar dam across the Krishna River to release floodwater. This is a critical step to manage the reservoir's water level, which is nearing its full capacity of 590 feet (Full Reservoir Level).
The dam’s water level recently reached 585.40 feet, prompting the lifting of gates by up to five feet to safely discharge the inflows downstream. The inflow measured around 3.54 lakh cusecs, with approximately 3.14 lakh cusecs being released to maintain flood control. The water release also supports irrigation for around 26 lakh acres of farmland spanning Telangana and Andhra Pradesh. The hydroelectric power station at the dam continues to generate over 815 MW of electricity during this period.
This marks one of the largest floodwater releases seen in recent years at Nagarjuna Sagar, with authorities closely monitoring the situation to prevent downstream flooding and infrastructure damage. The lifting of gates after such heavy rains is vital to regulate storage levels amidst monsoon excess and safeguard surrounding regions.
FREQUENTLY ASKED QUESTIONS
Why were the crest gates of Nagarjuna Sagar dam lifted?
The gates were lifted to release excess floodwater due to heavy upstream inflows, ensuring the reservoir does not exceed its full capacity and to prevent flooding downstream.
How many gates were lifted and to what height?
A total of 22 crest gates were lifted, with some raised up to five feet to facilitate controlled water discharge.
What is the current water level of the Nagarjuna Sagar reservoir?
The reservoir’s water level is approximately 585.40 feet, approaching the full reservoir level of 590 feet.
How much water is being released from the dam?
Around 3.14 lakh cusecs of water is being discharged downstream to manage inflows and support irrigation canals.
What areas benefit from the water released at Nagarjuna Sagar?
The released water supports irrigation for approximately 26 lakh acres of farmland across Telangana and Andhra Pradesh.
Is power generation affected during the release?
No, the dam's hydroelectric power station continues to generate electricity, contributing around 815 MW to the grid.
Has this kind of gate lifting happened before in July?
This year’s lifting of gates in July is the first time in about 18 years, indicating an unusual volume of monsoon inflows.
What measures are in place to avoid downstream flooding?
Water release is carefully regulated by adjusting gate heights and flow rates, and authorities continuously monitor downstream impact for flood management.
