AEAG — SDAGE 2022-2027 — DOE, DCR

Description

Provision C3 of SDAGE 2022-2027: Definitions of reference flow rates Table C3 and Map C3 determine, on the main hydrological axes of the basin, a network of nodal points for which DOE and DCR values are defined. At each nodal point, the DOE value is indicated during the low period as a daily average value. On the replenished axes, to take account of situations of severe lows and management constraints, the objective of low support can be adapted by the prefect coordinator of the sub-basin in consultation with all the actors involved in the management of the crisis (see C21 and C26). The assessment of the situation will be based in particular on the elements of multi-annual and local knowledge with a shared analysis in particular with the bodies managing low support support. This consultation should take into account the analysis of the volumes that must remain available to ensure the needs of the community and the reconciliation of uses until the end of the period of lowing. It also incorporates the objective of compliance a posteriori with the rule of satisfaction of the DOE 8 out of 10 years laid down in the regulations. This management principle therefore remains unchanged compared to 2016 2021. In small basins with no DOE value, additional objective flows can be defined in the SAGEs to organise water management in the territory concerned. They are then established on the basis of reliable measures consistent with the DOEs and DCRs of the rivers of which they are the tributaries and must be satisfied under the same conditions. The value of the DCR is imperatively saved as a daily average value.
