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.
§ 5
The effectiveness of the
This Decree shall take effect on the date of 15. March 2011.
