Why did Cauvery panel order Karnataka to release water?, Pg12

Key Highlights:

• The Cauvery Water Management Authority (CWMA) endorsed the Cauvery Water Regulation Committee (CWRC) order for water release.
• Karnataka was directed to release 3,500 cusecs of water to Tamil Nadu for 15 days, starting July 29.
• This release amounts to approximately 4.5 tmc ft of water.
• The decision was prompted by scanty rainfall in the Cauvery catchment area and Tamil Nadu's demand for its share.

Detailed Insights:

• The CWRC operates under the CWMA, which is the implementing body for the Cauvery Water Disputes Tribunal award, as modified by the Supreme Court in 2018.
• The committee monitors daily water levels, inflows, and storage in key reservoirs across Karnataka, Tamil Nadu, and Kerala.
• Decisions during distress are based on hydro-meteorological conditions, rainfall forecasts, reservoir storage, and flow at Biligundulu.
• Karnataka expressed dissatisfaction, noting a 60% shortfall in net inflow to its reservoirs compared to 30-year data.
• Tamil Nadu considers the ordered quantity insufficient, estimating a deficit of 9.8 tmc ft and requiring significantly more for its cultivation seasons.
• Both states need to develop a distress-sharing formula to manage water allocation effectively during periods of low rainfall.

Key Concepts Involved:

• Cauvery Water Management Authority (CWMA): An institution responsible for implementing the final award of the Cauvery Water Disputes Tribunal.
• Cauvery Water Regulation Committee (CWRC): A committee under the CWMA that monitors water levels and regulates releases based on prevailing conditions.
• Cauvery Water Disputes Tribunal: A judicial body established to resolve the long-standing water dispute among the riparian states of the Cauvery River.
• Cusecs (Cubic Feet Per Second): A unit of flow rate, representing the volume of one cubic foot of water passing a point per second.
• TMC ft (Thousand Million Cubic Feet): A unit of volume, commonly used to measure large quantities of water in reservoirs or river flows.
