Reservoir operation and flooding
Former Director General of Irrigation, G.T. Dharmasena, in an article, titled “Revival of Innovative systems for reservoir operation and flood forecasting” in The Island of 17 December, 2025, starts out by stating:
“Most reservoirs in Sri Lanka are agriculture and hydropower dominated. Reservoir operators are often unwilling to acknowledge the flood detention capability of major reservoirs during the onset of monsoons. Deviating from the traditional priority for food production and hydropower development, it is time to reorient the operational approach of major reservoirs operators under extreme events, where flood control becomes a vital function. While admitting that total elimination of flood impacts is not technically feasible, the impacts can be reduced by efficient operation of reservoirs and effective early warning systems”.
Addressing the question often raised by the public as to “Why is flooding more prominent downstream of reservoirs compared to the period before they were built,” Mr. Dharmasena cites the following instances: “For instance, why do (sic) Magama in Tissamaharama face floods threats after the construction of the massive Kirindi Oya reservoir? Similarly, why does Ambalantota flood after the construction of Udawalawe Reservoir? Furthermore, why is Molkawa, in the Kalutara District area, getting flooded so often after the construction of Kukule reservoir”?
“These situations exist in several other river basins, too. Engineers must, therefore, be mindful of the need to strictly control the operation of the reservoir gates by their field staff. (Since) “The actual field situation can sometimes deviate significantly from the theoretical technology… it is necessary to examine whether gate operators are strictly adhering to the operational guidelines, as gate operation currently relies too much on the discretion of the operator at the site”.
COMMENT
For Mr. Dharmasena to bring to the attention of the public that “gate operation currently relies too much on the discretion of the operator at the site”, is being disingenuous, after accepting flooding as a way of life for ALL major reservoirs for decades and not doing much about it. As far as the public is concerned, their expectation is that the Institution responsible for Reservoir Management should, not only develop the necessary guidelines to address flooding but also ensure that they are strictly administered by those responsible, without leaving it to the arbitrary discretion of field staff. This exercise should be reviewed annually after each monsoon, if lives are to be saved and livelihoods are to be sustained.
IMPACT of GATE OPERATION on FLOODING
According to Mr. Dhamasena, “Major reservoir spillways are designed for very high return periods… If the spillway gates are opened fully when reservoir is at full capacity, this can produce an artificial flood of a very large magnitude… Therefore, reservoir operators must be mindful in this regard to avoid any artificial flood creation” (Ibid). Continuing, he states: “In reality reservoir spillways are often designed for the sole safety of the reservoir structure, often compromising the safety of the downstream population. This design concept was promoted by foreign agencies in recent times to safeguard their investment for dams. Consequently, the discharge capacities of these spill gates significantly exceed the natural carrying capacity of river(s) downstream” (Ibid).
COMMENT
The design concept where priority is given to the “sole safety of the structure” that causes the discharge capacity of spill gates to “significantly exceed” the carrying capacity of the river is not limited to foreign agencies. Such concepts are also adopted by local designers as well, judging from the fact that flooding is accepted as an inevitable feature of reservoirs. Since design concepts in their current form lack concern for serious destructive consequences downstream and, therefore, unacceptable, it is imperative that the Government mandates that current design criteria are revisited as a critical part of the restoration programme.
CONNECTIVITY BETWEEN GATE OPENINGS and SAFETY MEASURES
It is only after the devastation of historic proportions left behind by Cyclone Ditwah that the Public is aware that major reservoirs are designed with spill gate openings to protect the safety of the structure without factoring in the consequences downstream, such as the safety of the population is an unacceptable proposition. The Institution or Institutions associated with the design have a responsibility not only to inform but also work together with Institutions such as Disaster Management and any others responsible for the consequences downstream, so that they could prepare for what is to follow.
Without working in isolation and without limiting it only to, informing related Institutions, the need is for Institutions that design reservoirs to work as a team with Forecasting and Disaster Management and develop operational frameworks that should be institutionalised and approved by the Cabinet of Ministers. The need is to recognize that without connectivity between spill gate openings and safety measures downstream, catastrophes downstream are bound to recur.
Therefore, the mandate for dam designers and those responsible for disaster management and forecasting should be for them to jointly establish guidelines relating to what safety measures are to be adopted for varying degrees of spill gate openings. For instance, the carrying capacity of the river should relate with a specific openinig of the spill gate. Another specific opening is required when the population should be compelled to move to high ground. The process should continue until the spill gate opening is such that it warrants the population to be evacuated. This relationship could also be established by relating the spill gate openings to the width of the river downstream.
The measures recommended above should be backed up by the judicious use of the land within the flood plain of reservoirs for “DRY DAMS” with sufficient capacity to intercept part of the spill gate discharge from which excess water could be released within the carrying capacity of the river. By relating the capacity of the DRY DAM to the spill gate opening, a degree of safety could be established. However, since the practice of demarcating flood plains is not taken seriously by the Institution concerned, the Government should introduce a Bill that such demarcations are made mandatory as part of State Land in the design and operation of reservoirs. Adopting such a practice would not only contribute significantly to control flooding, but also save lives by not permitting settlement but permitting agricultural activities only within these zones. Furthermore, the creation of an intermediate zone to contain excess flood waters would not tax the safety measures to the extent it would in the absence of such a safety net.
CONCLUSION
Perhaps, the towns of Kotmale and Gampola suffered severe flooding and loss of life because the opening of spill gates to release the unprecedented volumes of water from Cyclone Ditwah, was warranted by the need to ensure the safety of Kotmale and Upper Kotmale Dams.
This and other similar disasters bring into focus the connectivity that exists between forecasting, operation of spill gates, flooding and disaster management. Therefore, it is imperative that the government introduce the much-needed legislative and executive measures to ensure that the agencies associated with these disciplines develop a common operational framework to mitigate flooding and its destructive consequences. A critical feature of such a framework should be the demarcation of the flood plain, and decree that land within the flood plain is a zone set aside for DRY DAMS, planted with trees and free of human settlements, other than for agricultural purposes. In addition, the mandate of such a framework should establish for each river basin the relationship between the degree to which spill gates are opened with levels of flooding and appropriate safety measures.
The government should insist that associated Agencies identify and conduct a pilot project to ascertain the efficacy of the recommendations cited above and if need be, modify it accordingly, so that downstream physical features that are unique to each river basin are taken into account and made an integral feature of reservoir design. Even if such restrictions downstream limit the capacities to store spill gate discharges, it has to be appreciated that providing such facilities within the flood plain to any degree would mitigate the destructive consequences of the flooding.

Misinterpreting President Dissanayake on National Reconciliation
President Anura Kumara Dissanayake has been investing his political capital in going to the public to explain some of the most politically sensitive and controversial issues. At a time when easier political choices are available, the president is choosing the harder path of confronting ethnic suspicion and communal fears. There are three issues in particular on which the president’s words have generated strong reactions. These are first with regard to Buddhist pilgrims going to the north of the country with nationalist motivations. Second is the controversy relating to the expansion of the Tissa Raja Maha Viharaya, a recently constructed Buddhist temple in Kankesanturai which has become a flashpoint between local Tamil residents and Sinhala nationalist groups. Third is the decision not to give the war victory a central place in the Independence Day celebrations.
Even in the opposition, when his party held only three seats in parliament, Anura Kumara Dissanayake took his role as a public educator seriously. He used to deliver lengthy, well researched and easily digestible speeches in parliament. He continues this practice as president. It can be seen that his statements are primarily meant to elevate the thinking of the people and not to win votes the easy way. The easy way to win votes whether in Sri Lanka or elsewhere in the world is to rouse nationalist and racist sentiments and ride that wave. Sri Lanka’s post independence political history shows that narrow ethnic mobilisation has often produced short term electoral gains but long term national damage.
Sections of the opposition and segments of the general public have been critical of the president for taking these positions. They have claimed that the president is taking these positions in order to obtain more Tamil votes or to appease minority communities. The same may be said in reverse of those others who take contrary positions that they seek the Sinhala votes. These political actors who thrive on nationalist mobilisation have attempted to portray the president’s statements as an abandonment of the majority community. The president’s actions need to be understood within the larger framework of national reconciliation and long term national stability.
Reconciler’s Duty
When the president referred to Buddhist pilgrims from the south going to the north, he was not speaking about pilgrims visiting long established Buddhist heritage sites such as Nagadeepa or Kandarodai. His remarks were directed at a specific and highly contentious development, the recently built Buddhist temple in Kankesanturai and those built elsewhere in the recent past in the north and east. The temple in Kankesanturai did not emerge from the religious needs of a local Buddhist community as there is none in that area. It has been constructed on land that was formerly owned and used by Tamil civilians and which came under military occupation as a high security zone. What has made the issue of the temple particularly controversial is that it was established with the support of the security forces.
The controversy has deepened because the temple authorities have sought to expand the site from approximately one acre to nearly fourteen acres on the basis that there was a historic Buddhist temple in that area up to the colonial period. However, the Tamil residents of the area fear that expansion would further displace surrounding residents and consolidate a permanent Buddhist religious presence in the present period in an area where the local population is overwhelmingly Hindu. For many Tamils in Kankesanturai, the issue is not Buddhism as a religion but the use of religion as a vehicle for territorial assertion and demographic changes in a region that bore the brunt of the war. Likewise, there are other parts of the north and east where other temples or places of worship have been established by the military personnel in their camps during their war-time occupation and questions arise regarding the future when these camps are finally closed.
There are those who have actively organised large scale pilgrimages from the south to make the Tissa temple another important religious site. These pilgrimages are framed publicly as acts of devotion but are widely perceived locally as demonstrations of dominance. Each such visit heightens tension, provokes protest by Tamil residents, and risks confrontation. For communities that experienced mass displacement, military occupation and land loss, the symbolism of a state backed religious structure on contested land with the backing of the security forces is impossible to separate from memories of war and destruction. A president committed to reconciliation cannot remain silent in the face of such provocations, however uncomfortable it may be to challenge sections of the majority community.
High-minded leadership
The controversy regarding the president’s Independence Day speech has also generated strong debate. In that speech the president did not refer to the military victory over the LTTE and also did not use the term “war heroes” to describe soldiers. For many Sinhala nationalist groups, the absence of these references was seen as an attempt to diminish the sacrifices of the armed forces. The reality is that Independence Day means very different things to different communities. In the north and east the same day is marked by protest events and mourning and as a “Black Day”, symbolising the consolidation of a state they continue to experience as excluding them and not empathizing with the full extent of their losses.
By way of contrast, the president’s objective was to ensure that Independence Day could be observed as a day that belonged to all communities in the country. It is not correct to assume that the president takes these positions in order to appease minorities or secure electoral advantage. The president is only one year into his term and does not need to take politically risky positions for short term electoral gains. Indeed, the positions he has taken involve confronting powerful nationalist political forces that can mobilise significant opposition. He risks losing majority support for his statements. This itself indicates that the motivation is not electoral calculation.
President Dissanayake has recognized that Sri Lanka’s long term political stability and economic recovery depend on building trust among communities that once peacefully coexisted and then lived through decades of war. Political leadership is ultimately tested by the willingness to say what is necessary rather than what is politically expedient. The president’s recent interventions demonstrate rare national leadership and constitute an attempt to shift public discourse away from ethnic triumphalism and toward a more inclusive conception of nationhood. Reconciliation cannot take root if national ceremonies reinforce the perception of victory for one community and defeat for another especially in an internal conflict.

Recovery of LTTE weapons
I have read a newspaper report that the Special Task Force of Sri Lanka Police, with help of Military Intelligence, recovered three buried yet well-preserved 84mm Carl Gustaf recoilless rocket launchers used by the LTTE, in the Kudumbimalai area, Batticaloa.
These deadly weapons were used by the LTTE SEA TIGER WING to attack the Sri Lanka Navy ships and craft in 1990s. The first incident was in February 1997, off Iranativu island, in the Gulf of Mannar.
Admiral Cecil Tissera took over as Commander of the Navy on 27 January, 1997, from Admiral Mohan Samarasekara.
The fight against the LTTE was intensified from 1996 and the SLN was using her Vanguard of the Navy, Fast Attack Craft Squadron, to destroy the LTTE’s littoral fighting capabilities. Frequent confrontations against the LTTE Sea Tiger boats were reported off Mullaitivu, Point Pedro and Velvetiturai areas, where SLN units became victorious in most of these sea battles, except in a few incidents where the SLN lost Fast Attack Craft.

Carl Gustaf recoilless rocket launchers
The intelligence reports confirmed that the LTTE Sea Tigers was using new recoilless rocket launchers against aluminium-hull FACs, and they were deadly at close quarter sea battles, but the exact type of this weapon was not disclosed.
The following incident, which occurred in February 1997, helped confirm the weapon was Carl Gustaf 84 mm Recoilless gun!
DATE: 09TH FEBRUARY, 1997, morning 0600 hrs.
LOCATION: OFF IRANATHIVE.
FACs: P 460 ISRAEL BUILT, COMMANDED BY CDR MANOJ JAYESOORIYA
P 452 CDL BUILT, COMMANDED BY LCDR PM WICKRAMASINGHE (ON TEMPORARY COMMAND. PROPER OIC LCDR N HEENATIGALA)
OPERATED FROM KKS.
CONFRONTED WITH LTTE ATTACK CRAFT POWERED WITH FOUR 250 HP OUT BOARD MOTORS.
TARGET WAS DESTROYED AND ONE LTTE MEMBER WAS CAPTURED.
LEADING MARINE ENGINEERING MECHANIC OF THE FAC CAME UP TO THE BRIDGE CARRYING A PROJECTILE WHICH WAS FIRED BY THE LTTE BOAT, DURING CONFRONTATION, WHICH PENETRATED THROUGH THE FAC’s HULL, AND ENTERED THE OICs CABIN (BETWEEN THE TWO BUNKS) AND HIT THE AUXILIARY ENGINE ROOM DOOR AND HAD FALLEN DOWN WITHOUT EXPLODING. THE ENGINE ROOM DOOR WAS HEAVILY DAMAGED LOOSING THE WATER TIGHT INTEGRITY OF THE FAC.
THE PROJECTILE WAS LATER HANDED OVER TO THE NAVAL WEAPONS EXPERTS WHEN THE FACs RETURNED TO KKS. INVESTIGATIONS REVEALED THE WEAPON USED BY THE ENEMY WAS 84 mm CARL GUSTAF SHOULDER-FIRED RECOILLESS GUN AND THIS PROJECTILE WAS AN ILLUMINATER BOMB OF ONE MILLION CANDLE POWER. BUT THE ATTACKERS HAS FAILED TO REMOVE THE SAFETY PIN, THEREFORE THE BOMB WAS NOT ACTIVATED.

Sea Tigers
Carl Gustaf 84 mm recoilless gun was named after Carl Gustaf Stads Gevärsfaktori, which, initially, produced it. Sweden later developed the 84mm shoulder-fired recoilless gun by the Royal Swedish Army Materiel Administration during the second half of 1940s as a crew served man- portable infantry support gun for close range multi-role anti-armour, anti-personnel, battle field illumination, smoke screening and marking fire.
It is confirmed in Wikipedia that Carl Gustaf Recoilless shoulder-fired guns were used by the only non-state actor in the world – the LTTE – during the final Eelam War.
It is extremely important to check the batch numbers of the recently recovered three launchers to find out where they were produced and other details like how they ended up in Batticaloa, Sri Lanka?

Yellow Beatz … a style similar to K-pop!
Yes, get ready to vibe with Yellow Beatz, Sri Lanka’s awesome girl group, keen to take Sri Lankan music to the world with a style similar to K-pop!
With high-energy beats and infectious hooks, these talented ladies are here to shake up the music scene.
Think bold moves, catchy hooks, and, of course, spicy versions of old Sinhala hits, and Yellow Beatz is the package you won’t want to miss!
According to a spokesman for the group, Yellow Beatz became a reality during the Covid period … when everyone was stuck at home, in lockdown.
“First we interviewed girls, online, and selected a team that blended well, as four voices, and then started rehearsals. One of the cover songs we recorded, during those early rehearsals, unexpectedly went viral on Facebook. From that moment onward, we continued doing cover songs, and we received a huge response. Through that, we were able to bring back some beautiful Sri Lankan musical creations that were being forgotten, and introduce them to the new generation.”
The team members, I am told, have strong musical skills and with proper training their goal is to become a vocal group recognised around the world.
Believe me, their goal, they say, is not only to take Sri Lanka’s name forward, in the music scene, but to bring home a Grammy Award, as well.
“We truly believe we can achieve this with the love and support of everyone in Sri Lanka.”
The year 2026 is very special for Yellow Beatz as they have received an exceptional opportunity to represent Sri Lanka at the World Championships of Performing Arts in the USA.
Under the guidance of Chris Raththara, the Director for Sri Lanka, and with the blessings of all Sri Lankans, the girls have a great hope that they can win this milestone.
“We believe this will be a moment of great value for us as Yellow Beatz, and also for all Sri Lankans, and it will be an important inspiration for the future of our country.”
Along with all the preparation for the event in the USA, they went on to say they also need to manage their performances, original song recordings, and everything related.

The year 2026 is very special for Yellow Beatz
“We have strong confidence in ourselves and in our sincere intentions, because we are a team that studies music deeply, researches within the field, and works to take the uniqueness of Sri Lankan identity to the world.”
At present, they gather at the Voices Lab Academy, twice a week, for new creations and concert rehearsals.
This project was created by Buddhika Dayarathne who is currently working as a Pop Vocal lecturer at SLTC Campus. Voice Lab Academy is also his own private music academy and Yellow Beatz was formed through that platform.
Buddhika is keen to take Sri Lankan music to the world with a style similar to K-Pop and Yellow Beatz began as a result of that vision. With that same aim, we all work together as one team.
“Although it was a little challenging for the four of us girls to work together at first, we have united for our goal and continue to work very flexibly and with dedication. Our parents and families also give their continuous blessings and support for this project,” Rameesha, Dinushi, Newansa and Risuri said.
Last year, Yellow Beatz released their first original song, ‘Ihirila’ , and with everything happening this year, they are also preparing for their first album.
