What is Odisha Check Dam Scheme?

Government of Odisha launched the scheme in 2010-11 to construct Check dams/In-stream storage structures in small rivers, streams and anicuts in major rivers and streams to utilize a part of surface runoff flowing down the sea.

Objective of Check Dam Scheme

The broad objectives of Check Dams (In-stream Storage Structures) are :
** to provide drinking water facilities in the villages along both the sides of river after monsoon period.
** to provide incidental irrigation to crops during late khariff and rabi by storing water at the end of monsoon, mainly through lifting devices.

** Irrigation use of water flowing down drainage channels.
** to divert water from perennial / semi-perennial streams in hilly areas for irrigation purpose.

** to recharge ground water.
** Other uses by villagers like bathing, washing, fishing, recreation etc. depending on location and potentiality.

To involve beneficiaries during execution of the project, Pani Panchayat (WUAs) would be formed during the process of selection of site for a check dam.

The infrastructure, once completed in all respect, would be handed over to Pani Panchayats for operation and maintenance. However, technical assistance required for operation and maintenance would be extended free of cost by the department.

Selection Criteria of Check Dam Scheme

The Check Dams will store or divert surplus water flowing to the sea at the end of monsoon. While selecting locations for construction of in-stream storage structure or check dams the following principles & priorities are to be followed.

** Blocks having less than 35% irrigation coverage to be considered.
** Areas where farmers are using traditional irrigation by constructing temporary cross bunds on streams.
** Where the farmers are willing to take up operation & maintenance of the structure.

** The newly constructed structure should not have any adverse impact on the hydrological efficacy of the existing, ongoing and future major, medium, minor (flow) irrigation and minor (lift) irrigation projects.

** In-stream storage will be developed near urban centers if suitable rivers and locations available for multipurpose domestic and irrigation use.

Though the purpose of the scheme is to be demand driven, hydrologically and technically feasible sites may be considered by DoWR and local people are to be consulted prior to taking any action for implementation.

The main emphasis on selection of a site will be proper use of water through people’s participation.

Salient Features & Types of Check Dams

The check dams or in-stream storage structures with or without gated arrangements are to be capable of safely releasing the anticipated design flood without affecting the safety of the structures with minimum afflux in the upstream.

Water can be stored in such a pond / reservoir towards the end of monsoon. Basing on the type of stream or nallah where the structure is proposed to be constructed the check dams may be divided into three categories.

To achieve these Guidelines for Exploitation of Surface Water by construction of Check Dams objectives three types of check dams have been selected primarily basing on the type of the stream.

1. Check dams, upto a height of 2.0 mt. can be constructed across small tributaries / nallah / drainage channel within the banks and streams in middle and higher reaches (within approx. 50 mts. wide)

2. Check dams in deltaic rivers/ drainage channel (lower reaches) (within approx 50 mts. wide).
3. Storage across major rivers and streams having higher width and huge flood water discharge.
