The Lower Coleroon Anicut has got a hoary past. It was constructed by Sir Arthur Cotton, the most illustrious Engineer of the period 1827 – 1836. The Lower Anicut was constructed in the year 1836 across the Coleroon river downstream of upper Anicut at the 67th mile, where the Coleroon river Branches off from River Cauvery. This Anicut is intended for the benefit of 1,31,903 Acres of land in the Thanjavur, Nagapattinam and Cuddalore districts. The irrigation needs will be met mainly from the regenerated Cauvery water and by supplementing supplies direct from Grand Anicut. Irrigation Supplies for three crops Viz. Kuruvai, Samba and Kullakar will have to be given for the Ayacut under this system. This Anicut system, therefore, functions effectively throughout the year except for a month of closure period for carrying out the maintenance repairs to the Anicut and shuttering arrangements.

In this Lower Anicut, the surplus arrangements are made in two arms: North Branch Regulator (Length 372 m) and South Branch Regulator (Length 493 m). The North Branch Regulator consisted of 30 Nos of Vent of span 10.16 m and height of 2.75 m and was fully equipped with an electrified motor for operating arrangements. The South Branch Regulator consists of 40 Nos of Vent of span 10.16 meters and a height of 2.75 m with an electrified motor for operating arrangements.

The Regulator has been designed to discharge 4.50 lakhs Cusecs of flood water. The maximum flood observed was 3,85,751 c/s in the year 8.7.1924 and in the year 1961 -1,77,415 C/s in 1972 -1,06,334 C/s, in 1977 -1,51,315 C/s in 1979 -1,74,594 c/s, 2005 -3,35,016 C/s in 2007 -1,17,023 C/s, in 2008 -1,09,428 C/s and 18.08.2018 – 2,19,707 C/s respectively. Therefore to discharge the unprecedented flood in the forthcoming monsoon, it is essential to electrify the operating system for effective control and monitoring of floods. Anaikarai Bridge is located at Km 100/6 of NH – 45c - Vikkravandi –Kumbakonam - Thanjavur Road and is under the maintenance of NHAI Near Anaikarai village of Thanjavur District.

The structure represents a milestone / turning points in development of irrigated agriculture and bears an exceptional testimony to development of agriculture and increase in food production along with the improvement of the economic condition of farmers;

The River Cauvery originated in Kudagu hills in Karnataka state, travelling 589 km and finally confluence in the Bay of Bengal in two places, Coleroon River confluence in Kodiyambalayam village, and Cauvery River confluence in Cauvery Poompattinam.

On the left side of the Coleroon river, 23 km away, the huge historical famous Veeranam lake was formed by the Aditya Chola tenure 1011 to 1037. The Chola king managed to excavate the link canal from the Coleroon river to the Veeranam tank using soldiers. Ancient Veeranam lake is fed by Vadavar and filled with water. With the help of bamboo and available local vegetation, clay balls using make the Temporary Coffer Dam was built slightly across the river year by year to fill the Veeranam Lake and cultivate the field that flows into the Coleroon River. Sometimes heavy floods in the Coleroon river drowned and overwashed the Temporary Coffer Dam at the time Drought Occurred premises area.

In the situation English Engineer Sir Arthur Cotton, while inspecting the river at Coleroon, was amazed to see the structure of the Corombu (Temporary coffer Dam) built across the river as well as the structure of the corombu and decided to build the gorge across the narrow passage where the fort was built across the river. He decided to use the raw material (Stones) on the distressed compound wall of the Gangai Konda Cholapuram temple created by King Rajendra Chola and the over reserved stones and dedicated the construction of the northern passage from 1827 to 1831 and the southern passage from 1831 to 1836. An example of this is the construction of a similar structure called the Upper Anicut. Therefore, it is proposed that the tomb can be considered an ancient symbol as it has been majestically displayed and fruitful for over 184 years.

Furthermore, it is proposed that the canopy built by the English Engineer Sir Arthur Cotton may be considered a monument, although it has fallen into disrepair and is still flourishing today. It is proposed to consider the Inspection Bungalow, Assistant Executive Engineer office and Resident, which was built about 30 feet above the river bank at the time of the construction of the canal, as an ancient symbol as it is well maintained and in use till date.

The first bridge to be built along the 108 km stretch of the Coleroon River is the Lower Anicut Bridge, the only bridge in use for 184 years to reach the southern districts of Chennai using via Lower Anicut Bridge. In the south branch, the bottom ten sluice arch gates were erected in 1924; the horizontal girders fixed (beam) of the bridge were made of steel imported from England and still stand majestically to this day.

The Lower Anicut surplus water was drained by a river with the river confluence with the Bay of Bengal, and the sea fish spread up to Lower Anicut. As a result, plenty of fish was available in the lower Anicut, and a fish-catching culture was developed in the nearby villages. Very old, famous fish market functioned in Lower Anicut.

The 6 km long ellipse shape islands between the Northern and Southern parts of the island are used as tourist destinations without being submerged by all the floods. The Lower Anicut road bridge is 184 years old monument arch bridge. Furthermore, the bridge at the bottom became a very large shape of an arch. Its length is 10.16 m (33.4 ft). And its height arch is 18 ft (Grown Height). Still they old arch bridge but used by transport.

The structure was ahead of its times in terms of project formulation, engineering design, construction techniques, dimensions of the structure itself, quantum of water diverted, and size of the command;

Engineering utility vis-à-vis designed utility

• The Lower Anicut was built with in-depth engineering and experiential knowledge.

• Only if the management manages the floodplain in Cauvery will it be the best vulnerable to the general public, and in case of failure, the height of the +16.875 m of the embankment at the bottom will affect the people.

• If the dam is closed during the +21.50 m flood season. The banks will break, and the water shortage will be alleviated due to the low rainfall during the rainy season.

• Also currently maintained capacity height 2.75 m or 9 feet not immediately built, Very first 2 feet next 4 feet again raised 6 feet in 1950 raised 8 feet. Raise the blow and study the consequences and present: Flood water is discharged without any harm to the public during floods. Currently, the water reservoir, 2.75 m shutter, lifts above the height of the arch bridge over the river to safely discharge 4.50,000 cubic feet of flood water, the affects the bridge (Deck Bridge) designed.

• The bed level height is designed to carry the stagnant water to the seven main irrigation canals and to the seven main lakes with a horizontal elevation of +46,34"+ 9'ft = 55.34" ft. Veeranam lake was chosen 184 years ago by a forensic expert to provide enough water for irrigation and to supply drinking water to Chennai, 240 km away.

• Nature of the earth, which is usually sloping from north to south, unnatural lower Anicut located south side, they discharge the water flow Northeast feed into Veeranam tank, Veeranam tank feed North end Sethiyathope Anicut and Chennai metro water, Sethiyathope Anicut feed north of Wallajah tank, Wallajah tank feed Perumal tank through the Paravanaru river, Perumal tank water confluence in Bay of Bengal near Cuddalore OT above chain of activities depend on chosen bed level of Lower Anicut. Currently, efforts are being made to connect the rivers. But for the past 184 years back, the river has been an example of downstream connections connecting the Cauvery and Vellar Rivers.

• The Flood water indirectly facilitates multiple thousands of acres. It is also set up to facilitate groundwater supply and flood drainage main purpose of Irrigation.

Present State of Conservation

• Although the lower anicut is 187 Years old, it is still magnificently maintained by the maintenance work done on it in different eras.

• Is there something very carefully done whenever there is heavy flood discharged Coleroon river at the bottom of foundations, aprons of Lower Anicut, Public works Department workers find any crumbled that it is protected from damage by repairing it immediately.

• An earth cushion was placed on the upper part of the arch on the Lower Anicut bridge, and a road was built on it to facilitate vehicular traffic. In some places, the earth's cushion caused damage to the surface. After examining this, the first cement road was laid from the left bank to the right bank in the year 1941.

• Up to 1950, 6 feet of water was stored and supplied for irrigation. From time to time, there was a shortage of water, and to rectify it, the 8 feet storage height raised water and provided for agriculture and irrigation.

• The shutter height, which was 8 feet from 1950 to 1973, was again raised to 9 feet in 1973 and 1980 due to a shortage. To this end, the old Deck Bridge was raised in the new development plan as it could only be protected from flooding, and the water could be stored up to 8 feet 9 feet in height. Somewhere, floods passed lower Anicut due to some cracks developed in the bottom parapet and piers. The instant was conveyed to Cauvery technical cell chairman Thiru A. Mohana Krishnan, leader, then carefully inspected various parts of the lower Anicut bridge on 09.05.2009. Advised that Guniting work can be carried out to repair cracks in the pillar area, and traffic was restricted from two-way traffic to one-way traffic. With the aid of NABARD bank, the works carried out satisfactory better lower anicut bridge came out of use.

• After that, somewhere flood passed the lower anicut North and South Branch apron disturbed by flood and crocodiles. The DRIP Dam Safety Review Panel Engineers inspected affected the southern and northern branch Apron crocodiles by digging small ditches during the 2012 floods they did. It was implemented and maintained by the DRIP work in 2016 - 2017.

• 14.08.2018 Extreme levels of flood danger were announced in at least 2,22,000 cubic feet on 17.08.2018. Heavy vehicular traffic was temporarily banned due to the age of the bridge and the extent of flooding.

• In such an environment, the Chief Engineer's Committee of the Public Works Department advised that reputed educational institutions such as should be allowed to inspect the durability of the bridge and allow vehicular traffic, considering the usage of water supply for agriculture on the lower anicut bridge due to the collapse of the Upper Anicut Bridge built by Sir Arthur Cotton, who built both, at time contemporaries on 24.08.2018.

• Following the acquisition of heavy vehicle traffic, the IIT Chennai team conducted various inspections at the bottom and certified that the bridge could allow traffic of up to ten tonnes. Very Stable 22.07.2020. Many of the maintenance work was carried out on a war footing basis at various stages, but despite all the contemporary bridges built with it collapsing, the lower bridge still looks majestic and is still in use today.
