The Godavari basin receives major part of its rainfall during the Southwest monsoon period. The other rainy seasons are not so well defined and well spread as the South-West monsoon season. The annual rainfall of Godavari basin varies from mm to mm. The Godavari basin has a tropical climate. The mean annual surface temperature in the Western Ghat area is about 24 o C, and it increases gradually towards the east and attains a maximum of The mean maximum daily temperature generally exceeds 30 o C in the western part of the Godavari basin and it is only slightly less than 30 o C in the Eastern part.
The population of the basin, based on census was The density of population is around persons per km 2. Except for the hills forming the watershed around the basin, the entire drainage basin of the river Godavari comprises of undulating country, a series of ridges and valleys interspersed with low hill ranges.
Large flat areas which are characteristic of the Indo-Gangetic plains are scarce except in the delta. Godavari basin faces flooding problem in its lower reaches. The coastal areas are cyclone-prone. The delta areas face drainage congestion due to flat topography. A large portion of Maharashtra falling Marathwada in the basin is drought prone. Agreement of between the Governments of madras and Orissa regarding the development of hydro- electric power of Duduma falls on the Machkund river.

It originates in Balaghat range of hills, runs in south-east direction up to Manjira barrage in Telangana and from there in north direction till its confluence with Godavari.
The principal tributaries of Manjira are Terna, Karanja and Haldi joining it from right side; and Lendi and Maner which join from the left. It comprises the river Godavari from its confluence with the Manjira to its confluence with Pranahita.
It is an inter- State sub-basin between the States of Telangana and Maharashtra. It includes the direct catchment of the Godavari in this reach as well as that of its tributaries, except Maner and Pranahita. Main water resources projects are Pochampad dam, Kadam dam, Sripad Yellampalli barrage, Sundilla barrage and Annaram barrage.
The last two barrages are part of Kaleshwaram project. The river Maner the right bank tributary originates at an altitude of about m in Rajanna Sirisilla district of Telangana and it joins the Godavari river at an altitude of about m upstream of Annaram barrage. The entire catchment of the Maner lies in the State of Telangana.
Upper Maner, Middle Maner and Lower Maner dams are the main water resource projects in this sub-basin. Penganga includes the entire catchment of the Penganga from its source to its confluence with the Wardha with all its tributaries. It is an inter-State sub-basin between the States of Telangana and Maharashtra and forms inter-State boundary between the two States.
Kayadhu, Pus, Arunavati, Waghadi and Khuni are important tributaries. Wardha comprises river Wardha from its source to its confluence with the Wainganga with all its tributaries but excluding the catchment of the Penganga. It also forms boundary between the States of Maharashtra and Telangana before its confluence with Wainganga.
Bembla and Wunna are important tributaries. Main Pranahita river forms boundary between the two States of Telangana and Maharashtra. It carries the combined waters of the Penganga, the Wardha and the Wainganga after confluence of Wardha and Wainganga. It meets Godavari River from its left bank about km below the Manjira confluence near Kaleshwaram temple town.
Lower Godavari consists of the Lower part of the river Godavari from its confluence with the Pranahita upto the sea. The sub basin includes the direct catchment of the Godavari in this reach with all its tributaries except Indravati and Sabari.
In this sub-basin, Godavari forms boundary between the States of Maharashtra and Telangana; between the States of Telangana and Chhattisgarh. Drainage area Km 2. Main Godavari including minor tributaries. Major Projects. Water Quality. Based on the systematic sampling of river water at many locations in the basin, its suitability for various purposes is determined by CPCB and as per the results, the quality is not as per the desired class and BOD remains the most critical parameter.
At many places, the desired class was B or C while the existing class was D. In the Godavari basin, the normal rainfall over the individual sub-basins varies widely. Godavari basin upstream of Nanded receives about mm in an average year while Indravati sub-basin receives 1, mm. During monsoon period, the eastern half of the basin receives about to 1, mm of rain every year while in the rest of the area, except a narrow Ghats strip, annual rainfall is between to mm.
Consequently eastern half of the basin is more prone to floods as compared to the west. Floods in the Godavari River are the result of heavy rains over the basin. Unprecedented floods occurred in the Godavari basin during August which were caused by a depression originated in the BoB. Godavari is the largest river in Peninsular India and third largest in India.
