DECREE



of 21 June 1999. February 2011



on the definition of bodies of surface water



Ministry of environment and Ministry of agriculture lays down

pursuant to § 21 para. 3 of Act No. 254/2001 Coll. on waters and amending certain

acts (the Water Act), as amended by Act No. 20/2004 Coll. and Act No.

150/2010 Coll.:



§ 1



The subject of the edit



This Decree incorporates the relevant provisions of the European Union) and the ' ^ 1 '

definition of surface water for the purpose of the survey and assessment of the State

these waters and processing of river basin management plans.



§ 2



Definition of terms



For the purposes of this Ordinance, means the



and surface water categories) a river or a Lake,



(b)) river flowing body of surface water in most of the after

the surface, which can flow in the flow under the surface, such as water flow

or channel,



(c)) the Lake body of standing surface water, such as the natural lake,

the water tank on a stream, pond, and an artificial lake,



d) surface water body type descriptive characteristics that

represent a simplification of the natural conditions that affect the composition of the

aquatic ecosystems.



§ 3



Definition of surface water



(1) a body of surface water is defined over watercourses ^ 2) as

continuous comprehensive sub unit, which enables the assessment of the State

surface waters and the implementation of the programmes of measures pursuant to section 26 of the water

the law.



(2) a body of surface water is classified into the categories of surface water and on

the basis of the descriptors set out in the annex to this Decree to

surface water body type.



§ 4



The definition of artificial and heavily modified surface water bodies



(1) a body of surface water can be defined as an artificial or heavily

affected if:



and the changes to the hydromorphological characteristics), which would be necessary to

achieving good ecological status would have significant service

adverse effects on:



1. the wider environment,



2. navigation, including port facilities, or recreation,



3. activities for which water is stored, such as drinking water supply,

power generation or irrigation,



4. adjustment of water conditions, flood protection, drainage, or



5. other equally important permanent human development activities,



b) useful features provided by the artificial or modified

characteristics of a surface water body cannot, for reasons of

technical feasibility or disproportionate costs, reasonably be achieved

other means, which would be significantly better from the standpoint of

environment.



(2) For artificial and heavily modified surface water bodies the Division into

surface water body types according to the descriptors

surface water categories listed in the annex to this Decree, which is

close as possible to the competent heavily influenced or artificial water body.
