Information required for the list of competent authorities

As required under Article 3(8), the Member States shall provide the following information on all competent

authorities within each of its river basin districts as well as the portion of any international river basin

district lying within their territory.

(i) Name and address of the competent authority — the official name and address of the

authority identified under Article 3(2).

(ii) Geographical coverage of the river basin district — the names of the main rivers within

the river basin district together with a precise description of the boundaries of the river basin district.

This information should as far as possible be available for introduction into a geographic information

system (GIS) and/or the geographic information system of the Commission (CISCO).

(iii) Legal status of competent authority — a description of the legal status of the competent

authority and, where relevant, a summary or copy of its statute, founding treaty or equivalent

legal document.

(iv) Responsibilities — a description of the legal and administrative responsibilities of each competent

authority and of its role within each river basin district.

(v) Membership — where the competent authority acts as a coordinating body for other competent

authorities, a list is required of these bodies together with a summary of the institutional

relationships established in order to ensure coordination.

(vi) International relationships — where a river basin district covers the territory of more than

one Member State or includes the territory of non-Member States, a summary is required of the

institutional relationships established in order to ensure coordination.

ANNEX II

1 SURFACE WATERS

Characterisation of surface water body types

Member States shall identify the location and boundaries of bodies of surface water and shall

carry out an initial characterisation of all such bodies in accordance with the following methodology.

Member States may group surface water bodies together for the purposes of this initial

characterisation.

(i) The surface water bodies within the river basin district shall be identified as falling within either

one of the following surface water categories - rivers, lakes, transitional waters or coastal

waters — or as artificial surface water bodies or heavily modified surface water bodies.

(ii) For each surface water category, the relevant surface water bodies within the river basin

district shall be differentiated according to type. These types are those defined using either

‘system A’ or ‘system B’ identified in section 1.2.

(iii) If system A is used, the surface water bodies within the river basin district shall first be differentiated

by the relevant ecoregions in accordance with the geographical areas identified

in section 1.2 and shown on the relevant map in Annex XI. The water bodies within each

ecoregion shall then be differentiated by surface water body types according to the descriptors

set out in the tables for system A.

(iv) If system В is used, Member States must achieve at least the same degree of differentiation

as would be achieved using system A. Accordingly, the surface water bodies within the river

basin district shall be differentiated into types using the values for the obligatory descriptors

and such optional descriptors, or combinations of descriptors, as are required to ensure that

type specific biological reference conditions can be reliably derived.

(v) For artificial and heavily modified surface water bodies the differentiation shall be undertaken

in accordance with the descriptors for whichever of the surface water categories most

closely resembles the heavily modified or artificial water body concerned.

(vi) Member States shall submit to the Commission a map or maps (in a GIS format) of the geographical

location of the types consistent with the degree of differentiation required under

system A.
