Heavy Inflows Trigger Spillway Discharge at Sriramsagar Dam

Quick summary

• Location: Sriramsagar Project, Nizamabad district, Telangana.
• Event: early discharge of floodwater from the spillway began on August 18 due to heavy rains in upstream catchment areas in Telangana and Maharashtra.
• As of 10:40 a.m., project engineers gradually increased the discharge using crest gates:

– Initial flow: 25,000 cusecs.
– Later escalated to 2 lakh cusecs utilizing 39 gates by evening.
– Flow decreased overtime to 1.32 lakh cusecs as inflow subsided later in the day.

• Historical precedent shows earlier spillway opening dates compared to last year (July for this year vs September last year).
• Water was released into reservoirs connected to Kaleshwaram project via Flood Flow Canal from Sunday onward:

– Initial release started at 3,000 cusecs, increased progressively up to 18,000 cusecs. This translates into approximately 1.5 tmc ft/day.

• Discharge from other projects supplementing Godavari’s flood levels:

– Singur & Nizamsagar projects contributing combined inflows of over 1.68 lakh cusecs.
– Downstream barrages and projects including Yellampally (1.69 lakh), Annaram (1.4 lakh), Medigadda (4.29 lakh) showing significant discharges alongside Mid Manair (18,600) and Kaddam (34,500).

Indian Opinion Analysis

The early discharge from Sriramsagar Project underscores the increasing intensity and irregularity of monsoon rainfall patterns in catchment areas spanning Telangana and Maharashtra regions compared with previous years’ timelines-a potential indicator tied closely with climate variability or regional hydrological shifts.

The interconnectedness between Sriramsagar and downstream storage facilities linked with large-scale initiatives such as the Kaleshwaram Lift irrigation Project reveals india’s progressive efforts toward efficient water management systems intended not only for irrigation sanitation but protecting communities vulnerable toward-flood-induced fallout beyond rural dependence agricultural livelihood chain buffers aka water harnessing user project/success<>engineering narrative crucially Last Linked momentum
