Irrigation: anonymous agricultural water sampling points — Isère

Water withdrawals important for irrigation are subject to a reporting or authorisation regime. Threshold values are defined according to type resources, underground or superficial, and stream flow. The counting or evaluation by appropriate means is required by law in order to to know precisely the volumes taken and thus to ensure control of the samples compatible with naturally available water. This data series gives the positioning of water sampling points in the middle natural for irrigation in 2003 These samples may be taken from the ground (cloth or karst circulation), at the emergence of a source, or in the surface water system (river or plan) water). For the sake of homogeneity, the same typology of the medium is used for all samples.
