Water Research Institute Small Water Reservoirs Database
The database is worked out, up-dated and actualised by the Water Research Institute yearly, this also is its administrator, its owner is the Ministry of Agriculture of the Slovak Republic - Water Management Section. It is being used by solving of several tasks and problems in different spheres of the water management.
The database provides information on:
Numbers of reservoirs according categories
Water reservoirs volumes (constant, storage, retention)
Areas flooded by reservoirs
List of database indicators of Small Water Reservoirs:
Hydrological sequence number - the hydrological sequence number (according a water resource map 1: 50 000 )
Name - name of the small reservoir
Stream - name of the stream
rkm - river kilometre of the water reservoir basin profile according a water resource map 1: 50 000
Community - number of community according ZVIR categorisation
Operator - dam operator
Administrator ? respective water works authority of the Slovak Water Management Enterprise, st ent. Banská Stiavnica
Category - Category of the water reservoir V - constructed
District - name of the district
Map - Number of the water supply map 1:50 000 with the reservoir profile
Year - first year of operation
Purpose - purposes that the small reservoir fulfils I - irrigations, FR - Fishraising, E - energy, P - protection, R - resort
Category - according the Decree 169/1975 No. 40 are reservoirs divided into the I - IV category, what makes the need of different technical dam equipment, as well as different requirements on technical and safety supervision for and of the respective categories
