Water Resources Act 1991

40 Obligation to take river flow etc. into account

(1) Without prejudice to sections 38(3) and 39(1) above, subsection (2) or, as the case may be, subsection (3) below shall apply where any application for a licence under this Chapter relates to abstraction from any inland waters or to obstructing or impeding the flow of any inland waters by means of impounding works.

(2) If, in the case of such an application as is mentioned in subsection (1) above, the application is made at a time when no minimum acceptable flow for the inland waters in question has been determined under Chapter I of this Part, the Authority, in dealing with the application, shall have regard to the considerations by reference to which, in accordance with section 21(4) and (5) above, a minimum acceptable flow for those waters would fall to be determined.

(3) If, in the case of such an application as is mentioned in subsection (1) above, the application is made at a time after a minimum acceptable flow for the waters in question has been determined under Chapter I of this Part, the Authority, in dealing with the application, shall have regard to the need to secure or, as the case may be, secure in relation to the different times or periods for which the flow is determined—

(a) that the flow at any control point will not be reduced below the minimum acceptable flow at that point; or

(b) if it is already less than that minimum acceptable flow, that the flow at any control point will not be further reduced below the minimum acceptable flow at that point.

(4) Without prejudice to sections 38(3) and 39(1) above, where—

(a) an application for a licence under this Chapter relates to abstraction from underground strata; and

(b) it appears to the Authority that the proposed abstraction is likely to affect the flow, level or volume of any inland waters which are neither discrete waters nor waters comprised in an order under section 33 above,

subsection (2) or, as the case may be, subsection (3) above shall apply as if the application related to abstraction from those waters.
