The data is categorised into watershed wise (basin-wise) annual availability of groundwater, current draft (utilisation), allocation for domestic and industrial needs, availability for future use (or the balance) and categorisation based on stage of development and rigorous statistical treatment of water levels. It also gives mandal wise resources, which are apportioned and derived from the watershed assessment.

The information comes in the form of tables and maps and is divided into two volumes. The first volume deals with the data as per the Central Groundwater Board while the second volume is by the State Groundwater Department.

The data provided in Volume I gives a watershed-wise assessment of the resource and covers the following issues:

• Rainfall
• Rivers of the state vis-à-vis watersheds
• National code for major river basins of the state
• Soils and agro-climatic zones
• Geological and hydrogeological characteristics
• Chemical quality
• Groundwater Estimation Methodology
• State level committee for estimation of groundwater
• Data collection and data base constraints
• Water level records
• Groundwater estimates 2007
• Recommendations for the management of groundwater resource based on the finding of groundwater assessment 2007

Data given in Volume II covers mandal-wise availability of the resource and covers the following issues:

• Salient features of groundwater resource, trends and management
• Groundwater resources & figures - 2007
• Groundwater interventions / suggestions
• Watershed wise categorization in the districts of Andhra Pradesh, Table 1
• Mandal wise categorization in the districts of Andhra Pradesh, Table 2
• Major river basins and 81 subbasins of Andhra Pradesh – Map
• District wise groundwater resources - 2007 of Andhra Pradesh – Table 3
• Tributary wise groundwater availability of Andhra Pradesh state - Table 4
• River wise groundwater availability of Andhra Pradesh state - Table 5
• Watershed and mandal-wise groundwater resources along with location details of assessment units of all the districts for the year 2007 - Srikakulam, Vizianagaram, Visakhapatnam, East Godavari, West Godavari, Krishna, Guntur, Prakasam, Nellore, Chittoor, Kadapa, Ananthapur, Kurnool, Mahaboobnagar, Rangareddy, Medak, Nizamabad, Adilabad, Karimnagar, Warangal, Khammam, Nalgonda
• District wise list of over exploited villages proposed for notification

The data will be of use to the state administrators and voluntary development organisations to plan for judicious development of the available resource and to adopt a cautious approach in utilizing the resource in over-exploited villages of the state.
