The Hon. Wasantha Piyathissa - Deputy Minister of Rural Development, Social Security and Community Empowerment
The Deputy Minister reported flooding along both banks of the Gal Oya in Ampara due to high storage at the D.S. Senanayake Samudraya, spill gate releases, and additional inflows, with a bund breach at Nehinnaikadu inundating about 3,000 acres of paddy. He said around 1,000 acres had been saved, another 1,000 acres might still be protected subject to weather, but more than 1,000 acres were damaged, while several roads and irrigation structures were also affected. He stated that temporary sandbagging and emergency work were being carried out by district officials, irrigation engineers, the tri-forces and Police, and that estimates and special DCC committees were being prepared for permanent flood control and Gal Oya river conservation measures.
Verbatim record (translated)
Machine-translated from Sinhala / Tamil / English¶ 01 Hon. Deputy Speaker, there is an emergency affecting farmers on both banks of the Gal Oya in Ampara. The D.S. Senanayake Samudraya has a capacity of 770,000 acre-feet; currently 730,000 acre-feet are stored, with water level at 108.3 feet (safety regulation requires opening spill gates beyond 104 feet). Five gates are open 15 inches, releasing 1,176 cusecs, plus inflows from Namal Oya and other reservoirs, totaling about 3,000 cusecs into Gal Oya. About 30 km downstream at Nehinnaikadu, a local tank bund breach inundated about 3,000 acres of paddy (both sown and newly transplanted). As waters recede, about 1,000 acres have been saved; engineers believe we can save around another 1,000 acres depending on weather. However, over 1,000 acres are damaged. For years, riverbank protection along Gal Oya has been neglected, causing recurrent breaches; current stabilization uses sandbagging by the District Secretary, Irrigation engineers, tri-forces, and Police.
¶ 02 Several roads—Mavadipalliya, Kittangi Navithanveli, Alayadivembu, Sangam Road, and Kalmunai North—are damaged or blocked. Prior rains also damaged irrigation systems and bunds. Temporary measures were taken; estimates are being prepared for permanent solutions. We have also set up a special DCC committee to formulate a flood control plan for Digamadulla District and another for Gal Oya river conservation. We are taking steps for full control going forward.
