Abundant storage in Thirumoorthy Dam raises hopes among farmers for water adequacy in tail-end areas of PAP Main Canal
At a recent meeting to discuss the issue, the farmers arrived at a decision to stage prolonged protests if the Water Resource Department fails to channel water to a height of 4.8 feet (from the existing 4.5 feet) at the zero point of Vellakovil branch canal.
Out of 2300 mcft (million cubic feet) drawn from the dam for supply through PAP main canal, the water distribution for Vellakoil branch should be one-eighth. Even if 20% of water transmission loss is factored in, the realisation has to be not less than 230 mcft at the zero point. 'But, the water realisation is only 170 mcft. This is not sufficient. At some locations in tail-end areas, water flow does not last even for two days. There is severe shortage of water for livestock, drinking purpose and irrigation,' P. Velusamy, president of PAP Vellakoil Branch Canal Water Conservation Movement said.
The farmers hope the Water Resources Department will deploy better water management methods this time around with abundant water in the Thirumoorthy Dam.
Against the full depth of 60 feet, the level in the dam rose up to 53.92 ft on Wednesday. The storage was 1483 mcft against capacity of 1744. Against inflow of 252 cusecs, discharge of 1160 cusecs was maintained. At the same day last year, the level was 31.1 feet and storage was 680 mcft.
Also, the usable storage of the system dams of Parambikulam Aliyar Project was estimated at 7269.92 mcft by the Water Resources Department, on Wednesday.
Official sources said the State Government has been promised funds by the Union Ministry of Jal Sakthi under Dam Rehabilitation and Improvement Project (DRIP). Phase II and III, co-financed by the World Bank and the Asian Infrastructure and Investment Bank. Thirumoorthy Dam figures among 145 out of 736 dams proposed in the two phases that are more than 60 years old.

Krishna delta farmers receive early water boost for Kharif season
VIJAYAWADA: In a crucial development for farmers in the Krishna delta, the Water Resources Department has begun releasing 6,847 cusecs of water daily from the Prakasam Barrage to expedite Kharif season operations and safeguard paddy crops in their early stages. The discharge began on June 15, nearly 15 to 20 days earlier than usual, following a directive from Chief Minister N Chandrababu Naidu to mitigate cyclone-related crop losses. According to Anicut Assistant Engineer Rajesh, the current daily discharge is sufficient to meet the Kharif irrigation needs across the delta. Initially, 1,000 cusecs per day was released, and it was gradually ramped up to the current level to stabilise early sowing and planting activities. At present, Krishna River is receiving 4,600 cusecs of surplus water from Munneru (Kesara) and an additional 3,867 cusecs from the Pulichintala Project, which are en route to the barrage. To supplement the Krishna water, authorities also began releasing Godavari water from the Pattiseema Lift Irrigation Scheme on Thursday. Water Resources Minister Nimmala Ramanaidu officially released the water by activating the pumps. While the initial plan was to pump 2,214 cusecs of Godavari water daily, only 708 cusecs is being lifted as of 6 pm on Friday, due to ongoing heavy rainfall in the Krishna River's upper catchment areas. KC Division Executive Engineer Ravi confirmed that currently, only two pumps are operating but added that the volume could be increased if needed. The Godavari water is expected to reach the Krishna canal system by Sunday. Interestingly, farmers across the delta region believe that Godavari water, rich in natural minerals, improves soil fertility and yields.

SCADA project to automate Chennai reservoirs operation makes slow progress; WRD aims to complete by Northeast monsoon
The project to automate the operation of the city reservoirs and develop decision support for water management has slowed down, as the Water Resources Department awaits the release of the National Disaster Mitigation Fund. Though the project was chalked out a year ago, it has not made significant progress in terms of instrumentation installation. However, the department is confident of completing the work by the onset of the Northeast monsoon, which brings in a major share of annual rainfall to Chennai. The opening of the floodgates of reservoirs, including Chembarambakkam and Red Hills, renews concerns on impending inundation in the downstream areas during every Northeast monsoon. In a key effort to reduce flooding, increase response time, and enable transparency in sharing reservoirs' storage data, the department will introduce the Supervisory Control and Data Acquisition (SCADA) based integrated reservoir automation system. Officials said work is in progress, however at a slow pace, for automated flood control and real-time monitoring of the storage. The project aimed at fixing automatic water level recorders, flow sensors, and gate sensors to automate shutters operation, manage water discharge during peak inflow, and reduce flood risk in low level areas. The department is constructing an integrated command control centre at Chepauk and connected with sub-control centres in Red Hills, Poondi and Chembarambakkam reservoirs. When the SCADA based system is in place, reservoirs' shutters can be operated remotely from Chepauk and analyse inflows and changes in water levels to control flood discharge. The integrated command centre would have graphical representations of the reservoirs' network-inflow rate from various points, outflow level, position of sluice gates and storage. Various real-time data would be analysed to assess the exact time required for the reservoirs to fill up and need to store or release water. The decision support system would also allow real-time sharing of information with other institutions and government agencies and enhance flood management. The Rs. 32 crore project will help accurately predict reservoir capacity and optimise water resource management during summer months, officials said. A 'Near line disaster recovery centre' is also being established in Alandur that would function as a backup location for critical data recovery and operation during extreme weather events. On the delay in project, officials said efforts are being taken to implement the project by this upcoming monsoon.

Channel to divert surplus water from Ambattur lake to Cooum river
Every Northeast monsoon, people in Korattur and the Ambattur Industrial Estate are forced to endure inundation and power outages for at least four days. To alleviate these recurring issues, a channel will soon be built to divert a portion of surplus water from Ambattur lake to Cooum river. The Water Resources Department (WRD) has kick-started the process of launching a ₹130-crore project to mitigate inundation in the western parts of the city. The work is likely to begin by this month-end. The lack of sufficient culverts along Pattaravakkam railway line to channel surplus water from Ambattur lake led to waterlogging in places such as the Ambattur Industrial Estate. The department had regulated outflows from waterbodies in Avadi, Ambattur, Ayapakkam and Paruthipattu. However, some parts continued to face inundation, officials said. J. Gopalakrishnan, president, Korattur Federation of Residents' Welfare Association said: 'The rainy season is often a nightmare for residents in low-level areas. Rainwater entered several houses on 27th, 28th, and 29th streets and Venkatraman Nagar, and residents suffered without electricity for four days. The channel must be built before the upcoming monsoon to avoid another year of misery.' The WRD is awaiting the Government Order to construct a five-km long channel to carry a portion of surplus water from Cookson Road junction in Ambattur industrial estate to Cooum river near Maduravoyal. The four-metre-wide channel, which would carry about 400 cubic feet per second (cusecs) of water, would reduce the burden on other waterways, including Otteri Nullah, and alleviate recurring floods in Korattur and Ambattur Industrial Estate. Surplus water from Ambattur lake otherwise travels through Pattaravakkam and Korattur, and drains into Korattur lake. From there, it flows into Otteri Nullah and Retteri lake through two weirs. Once the channel is built, only about 400 cusecs of rainwater from local catchment would travel through these localities before draining into Korattur lake, officials said. Ambattur MLA Joseph Samuel said various other measures were also on the cards. Funds are awaited to desilt and restore Korattur lake, and also improve North Canal in Korattur.
