The Dowleswaram Barrage was an irrigation structure originally built in 1852 on the lower stretch of the Godavari River before it empties into the Bay of Bengal. It was rebuilt in 1970 when it was officially renamed as Sir Arthur Cotton Barrage or Godavari Barrage. [1]

Geography

The Godavari River empties its water into the Bay of Bengal after flowing nearly fifty miles from the Dhavaleshwaram Barrage. Rajamahendravaram is a city situated on the left bank of Godavari River. Upstream, where the river is divided into two streams; the Gautami to the left and the Vasistha to the right, forms the joining line between the West Godavari and the East Godavari districts. The dam alignment crosses two mid stream islands.

Original Dowleswaram Barrage

The original Dowleswaram Barrage (also spelled Dowlaisweram or Dowlaiswaram) was built by a British irrigation engineer, Sir Arthur Thomas Cotton and completed in 1850. [2] The barrage was constructed in four sections, which allowed flood passage during the construction period. The Dowleswaram Barrage was 15 feet high and 3.5 km long.[ citation needed ]

Cotton's many projects averted famines and stimulated the economy of southern India. Before this barrage was constructed many hectares of land has been flooded with water and was unused. The water would be worthlessly going into sea. But when Sir Arthur Thomas Cotton had built the barrage those unused lands were brought into cultivation and the water was stored and used. The Cotton Museum was constructed on behalf of Cotton's memory. It is a tourist attraction in Rajamahendravaram.[ citation needed ]

Modern Sir Arthur Cotton Barrage / Godavari Barrage

Between 1970-82, the barrage was reconstructed to a height of 10.6 m. The reservoir at present has a gross storage capacity of 83 MCM(million cubic meters)(2.93 Tmc ft) and a dead storage of 2.02 Tmc ft at 40 feet (12 m) MSL. [3] The Barrage consists of 4 arms with 175 bays having a length of 3.599 Kms. It benefits 65 mandals of East and West Godavari with 2 crops annually supplying water utilisation of nearly 100 Tmc ft [4]

Inadequate water inflows

During the rabi season of 2022–23, adequate water is not supplied to the canals due to a lack of sufficient water inflows into the reservoir as sufficient water had not been stored earlier in the upstream Polavaram reservoir. The natural flows normally available during the dry season in the Godavari River are being stored in Medigadda and Sammakka Sagar reservoirs which used to be available for use in Godavari Delta. To build up the water level/storage in the Polavaram reservoir to enable adequate water release downstream, water is released from the Donkarayi reservoir directly without using it for power generation in the lower Sileru power station. [5] At least 60 tmcft water storage is needed in the Polavaram reservoir or up to the safe level limit of the upper coffer dam of the Polavaram Project to supply water to the total cropped area during the rabi season.

The Godavari is India's second longest river after the Ganga river and drains into the third largest basin in India, covering about 10% of India's total geographical area. Its source is in Trimbakeshwar, Nashik, Maharashtra. It flows east for 1,465 kilometres (910 mi), draining the states of Maharashtra (48.6%), Telangana (18.8%), Andhra Pradesh (4.5%), Chhattisgarh (10.9%) and Odisha (5.7%). The river ultimately empties into the Bay of Bengal through an extensive network of distributaries. Measuring up to 312,812 km2 (120,777 sq mi), it forms one of the largest river basins in the Indian subcontinent, with only the Ganga and Indus rivers having a larger drainage basin. In terms of length, catchment area and discharge, the Godavari is the largest in peninsular India, and had been dubbed as the Dakshina Ganga.

The Pranahita Chevella Lift Irrigation Project is a lift irrigation project to harness the water of Pranahita tributary of Godavari river for use in the Telangana state of India. The river water diversion barrage across the Pranahita river is located at Thammidihatti village in Komaram Bheem district of Telangana. This lift canal is an inter river basin transfer link by feeding Godavari river water to Krishna river basin. The chief ministers of Telangana and Maharashtra states reached an agreement in 2016 to limit the full reservoir level (FRL) of the barrage at 148 m msl with 1.85 tmcft storage capacity. In the year 2016, this project is divided into two parts. The scheme with diversion canal from the Thammmidihatti barrage to connect to existing Yellampalli reservoir across the Godavari river is presently called Pranahita barrage lift irrigation project. This scheme is confined to providing irrigation facility to nearly 2,00,000 acres in Adilabad district using 44 tmcft water.

The Government of India (GoI) constituted a common tribunal on 10 April 1969 to solve the river water utilization disputes about the river basin states of Godavari and Krishna rivers under the provisions of Interstate River Water Disputes Act – 1956. The common tribunal was headed by Sri RS Bachawat as its chairman with Sri DM Bhandari and Sri DM Sen as its members. Godavari river basin spreads through the states of Telangana (TS), Maharashtra (MR), Orissa, old Madhya Pradesh {later bifurcated into present Madhya Pradesh (MP) and Chhattisgarh}, Karnataka (K) and Andhra Pradesh (AP). Krishna river basin states Maharashtra, Karnataka and Andhra Pradesh insisted on the quicker verdict as it had become more expedient for the construction of irrigation projects in Krishna basin. So the Godavari Water Disputes Tribunal (GWDT) could not proceed till the Krishna Water Disputes Tribunal final verdict was submitted to GoI on 27 May 1976.
