Sileru River

Sileru River is a tributary of Sabari River. It originates in Andhra Pradesh and also flows through Odisha before merging with Sabari. Sabari river crosses the border into Andhra Pradesh to merge with Godavari river.[1] Sileru (known as Machkund in its upper reaches) river joins Sabari river tri-junction boundary point of Andhra Pradesh, Chhattisgarh and Odisha.habby

Hydro power potential

Sileru river has huge potential of hydro electricity generation which has been substantially harnessed by constructing Machkund (120 MW), Balimela (510 MW), Upper Sileru (240 MW), Donkarayi (25 MW) and Lower Sileru hydro (460 MW) power projects.[2] Chitrakonda (60 MW) hydro project located at the toe of Balimela earth dam is planned to utilise the head available across the earth dam.[3]

Irrigation potential

The water released from the Balimela power station is used for irrigation in the Potteru tributary basin of Sabari in Odisha. At present the water released from the other power stations is not useful to irrigation needs except during lean flow period in main Godavari river for the requirements of Godavari delta. Uttarandhra region can create huge irrigation potential with the perennial water supply from the available water storages in Seleru river basin. The mid lands of East Godavari district can get augmented water supply by diverting Sileru river water from Donkarayi reservoir (310 m MSL) towards east of Eastern Ghats by constructing 35 km long tunnel with enhanced power potential.[4] Similarly, mid lands of Vishakhapatnam District, Vizianagaram district and Srikakulam district can get augmented water supply by diverting Sileru river water from Guntawada weir (head works of Upper Sileru power station) at 410 m MSL towards east by constructing 30 km long tunnel with enhanced power potential.[5] The diverted water of Sileru river to the east can also be used to supply water to the Polavaram left bank canal and Visakhapatnam city's continuous drinking water needs when water level is not adequate in Polavaram reservoir during non monsoon months.

The water released from the Lower Sileru power station can be diverted to Yeleru reservoir by gravity with a 70 km long tunnel to create additional irrigation in East Godavari district. Part of the water released by Lower Sileru power station can also be used for the planned Lower Sileru irrigation scheme located in Sileru and Sabari basins.

Agaya Gangai

Agaya Gangai waterfalls are located in Kolli Hills of the Eastern Ghats, in India. Panchanathi, a jungle stream, cascades down as the Agaya Gangai (English: Ganges of Sky), near Arapaleeswarar temple atop the Kolli Hills in Namakkal district, Tamil Nadu. It is a 300 feet (91 m) waterfall of the river Aiyaru. It is located in a mountain valley.The caves of Korakka Siddhar and Kalaanginatha Siddhar are situated near the Agaya Gangai waterfalls in the nearby forest.

Balimela Reservoir

The Balimela Reservoir is located in Malkangiri district, Odisha, India on the river Sileru which is a tributary of the Godavari river. The gross storage capacity of Balimela reservoir is 3610 million cubic meters.Andhra Pradesh (AP) and Odisha states entered into agreements to construct Balimela dam as a joint project and share the Sileru river waters available equally at Balimela dam site. Odisha developed the 360 MW (6 × 60 MW units) power house by diverting the Balimela waters to the Potteru sub-river basin. A barrage at Surlikonda across the Potteru stream was constructed to redirect the discharge from Balimela Power House into two main canals for irrigation; one on the right side named Tamasha Main Canal and the second on the left side named Gompakonda Main Canal. These two canals were constructed under the Potteru Irrigation Project for irrigation in Malkangiri district, the most backward district of the state and thereby lifting the living standard of the inhabitants. Two more power generation units 75 MW each were added under stage-2 to increase the installed capacity up to 510 MW.

The share of Andhra Pradesh from the available water in the Belimela is released downstream into the river for generating hydro electricity located at Upper Sileru, Donkarai and lower Sileru Hydro power stations ultimately utilizing the water for irrigation in the Godavari delta during dry season.


The Erramala (Telugu: ఎఱ్ఱమల) are a range of low hills in southern India, in Kurnool district of Andhra Pradesh state. The Erramala hills lie on the Deccan plateau, running east-west and dividing the basin of the Penner River to the south from the basin of the Krishna River to the north. The Hill range may be extended along the Penner River basin in Kadapa district.

Some Important Visitor Attractions along the Erramala Hills are as follows

Belum Caves

Yadiki Caves



Kalva Bugga



Orvakal Rocks

Kethavaram Rock art site


OwkIn the east lies the higher Nallamalla Hills.

Gosthani River

Gosthani River is an east flowing river in Andhra Pradesh, India that flows from the Ananthagiri Hills of the Eastern Ghats into the Bay of Bengal.

Jalaput Dam

The Jalaput Dam is a hydroelectric dam built on the Machkund River, a tributary of the Godavari River in India which rises in the Mudugal hills of Visakhapatnam District and nearby Ondra Gadda it becomes the boundary between Andhra Pradesh and Odisha. For over 48 km the river runs nearly north along a meandering course through the Padwa Valley. About 48 km south of Jeypore, it winds westward along the edge of the Plateau and then suddenly tums at a short angle to the south-west down a steep descent popularly known as Duduma Falls.

Jalaput Dam (and Reservoir) impounds 34.273 Tmcft of water for the needs of down stream 120 MW Machkund Hydro-Electric Scheme (MHES), which is in operation since 1955. The dam and the MHES are the joint projects of Andhra Pradesh and Odisha states. The existing six number power generation units have become old and obsolete compared to latest technology. It is much economical to install a new hydro-electric scheme with a 15 km long tunnel using nearly 400 meters available level drop between Jalaput reservoir and the existing Balimela Reservoir back waters. There is also possibility to install huge capacity Pumped-storage hydroelectricity station for the needs of peaking power using high high water level drop. This reservoir will serve as upper pond and existing Balimela reservoir as tail pond for installing Pumped-storage hydroelectricity units. Thus this reservoir water can be put to use more productively. The existing MHES can also be kept in operation by diverting the surplus water from the nearby upper Kolab reservoir into the Machkund river basin by joining with nearly 4 km long tunnel. This would facilitate to use excess water from the upper Kolab reservoir for enhanced electricity generation in MHES and downstream Balimela power house by using nearly 200% more available head in Sileru river basin before putting finally for irrigation use.

Krishna Wildlife Sanctuary

Krishna Wildlife Sanctuary is a wildlife sanctuary and estuary located in Andhra Pradesh, India. It is one of the rarest eco-regions of the world because it harbors vast tracts of pristine mangrove forests. It is believed by conservationists to be one of the last remaining tracts of thick primary mangrove forests of South India, which is rapidly disappearing due to absence of protective measures.

Sabari River

Sabari River is one of the main tributaries of Godavari. It originates from the western slopes of Eastern Ghats in Odisha state from Sinkaram hill ranges at 1370 m MSL. It is also known as Kolab river in Odisha.The Sabari river basin receives nearly 1250 mm annual average rainfall. It forms common boundary between Chhattisgarh and Odisha states and later enters into Andhra Pradesh to merge with River Godavari. Upper Kolab project, located in Odisha across the Sabari is a major dam project supplying water for irrigation and Hydro power generation.

The 200 km long stretch of the river forming boundary between Chhattisgarh and Odisha drops by 2.25 meters per km length on average. This stretch of the river has substantial hydro electricity generation potential by building medium head (< 20 m) barrages in series to minimize land submergence. The surplus water of Indravati River in Odisha can also be diverted to Sabari river via Jaura Nallah through which Indravati flood waters naturally overflow into Sabari basin.

Sileru River (known as Machkund in its upper reaches) is the major tributary of Sabari which joins Sabari river at tri-junction boundary point of Andhra Pradesh, Chhattisgarh and Odisha.
