WATER INFORMATION SYSTEM of the Czech Republic

Guide to applications under the responsibility of the Ministry o f Agriculture Easily accessible information Reliable data Easy to navigate Effective information service The Ministry of Agriculture and the Ministry of the Environment, in cooperation with other central water authorities, provide comprehensive information about the waters of the Czech Republic to the general public. This data is clearly arranged, easily accessible and easy to understand, and is not only interesting but also very important for all the citizens of the Czech Republic. The WATER information system itself is already being developed, in way that focuses on targets, and the individual applications are being gradually published in a water management information portal known as WATER.

This portal is one of a number of fully expert portals dealing with water management issues; its website traffic (the number of individual visitors per day) amounts to several dozen thousand visits. It should be mentioned that this portal is a unique system even on a European level, and this fact is even more significant due to the qualified approach, in particular of the River Boards, state enterprises, to the issues in question and their willingness to help promote public awareness. We trust that you will find the website an interesting and much sought after source of information which will be, especially amidst fluctuating weather conditions and in relation to climate change, of invaluable importance.

The portal also features a logo depicting information provided about the waters of the Czech Republic (inverted water droplets), sponsored by the state administration (national tricolour). From 20 March 2008 you will see the portal logotype, which is being displayed first in this publication.

INTRODUCTION D O R T N I 1. Introduction 1.1. THE CZECH REPUBLIC The Czech Republic is a landlocked country in the centre of Europe, situated in the temperate climate zone of the Northern Hemisphere. It covers an area of 78,864 km 2 and has a population of almost 10.350 million. The state border is total 2,290.2 km long and shared with the following states: Germany (810.3 km); Austria (466.3 km); Slovakia (251.8 km) and Poland (761.8 km). Seven hundred and eighty-three kilometres of the state border are classified as a “wet border”, i.e. formed by boundary watercourses.

The Czech Republic is an important headwaters area of the European continent and in hydrological terms it can be called ”the roof of Europe“. It is situated in the watershed of three seas: the North Sea, the Baltic Sea and the Black Sea. Practically all of its major watercourses drain water into neighbouring states. The water sources of the Czech Republic are thus almost exclusively dependent on precipitation. The watersheds of the North, the Baltic and the Black Seas divide the Czech Republic into three main hydrological catchment areas: the basins of the River Elbe, the River Odra and the River Morava (Danube).

7 1.2. HYDROLOGAL SYSTEM OF THE CZECH REPUBLIC The hydrological system includes approximately 76,000 km of watercourses (with both natural and regulated stream channels). Under Public Notice No. 470/2001, as amended which determines the register of major watercourses and the methods of carrying out activities associated with administering them, the major watercourses total 15,536 km. They include the River Elbe (370 km), with the River Vltava (433 km), in Bohemia; the River Morava (272 km), with the River Dyje/Thaya (306 km), in South Moravia; and the River Odra (135 km), with the River Opava (131 km), in North Moravia and Silesia. The total length of the minor watercourses amounts to more than 60,000 km.

The hydrological system is formed, as mentioned above, by three main hydrological catchment areas: the basins of the River Elbe, the River Odra and the River Morava (Danube). In terms of the size of the Czech Republic the main river basins are, for planning purposes, further divided into eight hydrological river basin districts (river basin districts of the Upper and Middle Elbe, the Upper Vltava River, the River Berounka, the Lower Vltava River, the River Ohře and the Lower Elbe, the River Odra, the River Morava and the River Dyje/Thaya), which are administered by five River Boards, state enterprises: the Vltava River Board; the Ohře River Board the Elbe River Board); the Odra River Board and the Morava River Board.

CENTRAL WATER AUTHORITIES The competence of the central water authorities to carry out state administration activities relating to the waters of the Czech Republic is regulated by the provisions of Section 108 of Act No. 254/2001 on Water and Amendments to certain Acts, as amended (hereinafter referred to as the ”Water Act“). The Czech Republic has adopted a system of “shared powers” which in practice means that the jurisdiction of a central authority is shared by five ministries.

The area of jurisdiction of the Ministry of Agriculture as a central water authority is defined by the Water Act as residual with regard to all acts of state administration for which no area of jurisdiction of any other central water authority has been stipulated by an exhaustive definition.

The Ministry of the Environment for instance ensures the protection of water quantity and quality, monitoring and assessment of the status of waters, mitigating the impact of accidents, flood protection, meeting tasks in relation to the EC in the area of water protection etc. The Ministry of Health carries out in co-operation with the Ministry of the Environment the functions of a central water authority in designating surface waters suitable for bathing. The Ministry of Transport carries out the functions of a central water authority in terms of surface water use for navigation. The Ministry of Defence carries out the powers of a central water authority in matters constituting the jurisdiction of military districts. Water management administration in military districts, carried out in these territorial units by the military district authorities, is usually in connection with a specific situation.

9 1.4. WATERCOURSE ADMINISTRATORS UNDER THE RESPONSIBILITY OF THE MINISTRY OF AGRIGULTURE Watercourse administrators under the jurisdiction of the Ministry of Agriculture are responsible for the administration of more than 94.5% of the length of all watercourses in the Czech Republic. The administration of approximately of 5.5% watercourses is shared by the Ministry of Defence, the national park administration bodies or, as the case may be, by natural persons and legal entities. Watercourses in the Czech Republic are divided into major and minor/small watercourses. The expert administration of watercourses is carried out under the provisions of Section 47 of the Water Act.

Major watercourses, with a total length of 15,536 km, and a minor part of specified small watercourses, with a total length of 1,380 km, are administered by River Boards, state enterprises, i.e. the Vltava River Board, state enterprise (4,761 km of major watercourses), the Ohře River Board, state enterprise (2,290 km of major watercourses), the Elbe River Board, state enterprise (3,560 km of major watercourses), the Odra River Board, state enterprise (1,111 km of major watercourses) and the Morava River Board, state enterprise (3,813 km of major watercourses). The specific account of major watercourses is stated in Public Notice No. 470/2001, as amended, which lays down the list of major watercourses and the method of carrying out activities associated with administering them.

The activities of River Boards, state enterprises, are, in addition to Act No. 305/2000 on River Basins, specified by the subject of business activity, recorded in the Commercial Register and in the Memorandum of Association. The basic role of the state enterprise is to carry out the duties of a river basin administrator, an administrator of the major and the specified minor watercourses; operating and maintaining state-owned hydraulic structures that the state-owned company is authorised to manage; and inexercising rights and carrying out other duties and activities entrusted to the state enterprise. All the activities of the River Boards, state enterprises, focus on the protection and inspection of the quantity and quality of surface waters and groundwater; conservation of the environment where water occurs; maintenance and operation of water management and hydropower facilities and waterways; economical and efficient use of waters, general protection against the detrimental effects of water; and establishing conditions for general water use and effective use of tangible and intangible assets. The state-owned company acts within the scope of its activities and in accordance with legal regulations, on its own behalf and upon its own responsibility.

10 Minor/small watercourses are administered under the provisions of Section 48 of the Water Act. The majority of minor/small watercourses are administered by the Agricultural Water Management Authority (35,700 km) and by Forests of the Czech Republic, state enterprise (19,536 km). Minor/small watercourses are administered through delegation by the Ministry of Agriculture under the provisions of Section 48, Subsection 2 of the Water Act.

WATER INFORMATION SYSTEM R H E T T A F W OF THE CZECH REPUBLIC O 2. W ATER Information system of the Czech Republic 2.1. INFORMATION ABOUT THE PROJECT The WATER information system of the Czech Republic was officially launched in 2005 upon joint approval of the key documents (project aims, basic communication rules, joint objectives, graphic design manual and schedule of implementation of project tasks). The main impetus for implementing the project was the provisions of Section 22, Subsections 3 and 4 of the Water Act, which impose on the Ministry of Agriculture and the Ministry of the Environment the obligation to administer and operate the respective public administration information systems for keeping individual records under the provisions of Section 21, Subsection 2, Letter c) of the Water Act.

To this end, the Ministry of Agriculture, in co-operation with the Ministry of the Environment, produced Public Notice No. 391/2004 on the scope of data contained in records of surface water and groundwater status and on the method of processing, storing and presenting this data in public administration information systems. The Public Notice specifies in detail an overview of all records under the responsibility of the aforementioned ministries and lists all data registered under this Public Notice. The data is processed, presented and stored in the public administration information system. In addition to the responsibilities of the respective ministries for the above records, the Public Notice includes the direct responsibility of professionally qualified entities (under the jurisdiction of the individual water authorities) responsible for collecting and recording data in the scope of their operation information systems. The professionally qualified entities under the responsibility of the Ministry of Agriculture consist of the following bodies: River Boards, state enterprises, the Agricultural Water Management Authority and Forests of the Czech Republic, state enterprise. As regards the area of responsibility of the Ministry of the Environment, these entities comprise the following bodies: the Czech Hydrometeorological Institute and the T.G. Masaryk Water Management Research Institute, public research institution.

15 2.2. MAIN OBJECTIVES OF THE PROJECT The main objective of the interdepartmental project WATER Information System of the Czech Republic is the uniform presentation of water-related information, which is the responsibility of all central water authorities of the Czech Republic. It provides both the expert and lay public with a comprehensive source of trustworthy and relevant information about waters and serves as a basis for decision making and education, and as a means of promoting general awareness. The information is provided effectively in a unified manner, from one place. This interdepartmental project is co-ordinated by the Ministry of the Interior, which also provides inter alia the basic web hosting services of the portal.

At present, the Ministry of Agriculture and the Ministry of the Environment have a legal obligation to publish selected data relating to the water sector, in the public administration information system. The other central water authorities involved (the Ministry of Defence, the Ministry of Health and the Ministry of Transport) currently do not have this duty. Their active co-operation is, however, necessary to ensure the proper function of the uniform rules of the project. Obviously, if there is a need for the ministries to publish their data they have the option of presenting the information as part of this project at any time.

The objectives of the WATER information system of the Czech Republic

To independently present information on the division of competences in the water sector in the Czech Republic

To provide credible and relevant information in the water sector

To present information in one place

To present information about the water sector in a comprehensive manner, stating the data source

To present information in a single form

To help improve the carrying out state administration functions in water management

To build simple and effective open system

16 2.3. PROJECT ORGANISATION Implementation of the interdepartmental project, called the WATER Information System of the Czech Republic is scheduled for the 2005–2010 period. The area covered by this project includes individual project tasks (records), which are under the responsibility of the accountable ministries. They are obliged to present the respective data on behalf of these departments as part of the public administration information system (see the provisions of Section 21 of the Water Act).

The ministries involved, i.e. the Ministry of Agriculture and the Ministry of the Environment, implement and finance their respective project areas, based on documents approved by the Project Steering Committee and at the consultative meetings of the management of the ministries. For this reason, a schedule for the implementation of individual project tasks in the calendar year in question is submitted to the Ministry of Agriculture annually. The total estimate of funds necessary for creating the records under the responsibility of the Ministry of Agriculture in the years 2005–2010 amounts in total to CZK 5 million, excluding VAT. To ensure the successful implementation of this interdepartmental project a three-tier organisational structure was established, formed by the appointed representatives of all central water authorities and the Ministry of the Interior, in its capacity as project co-ordinator.

Project teams are set up consisting of representatives of the individual departmental organisations dealing with their own issues concerning the approved project tasks. The final setup of the project team is determined by the project manager.

17 2.4. WATER MANAGEMENT INFORMATION PORTAL – WATER The individual applications are gradually published on the water management information portal – WATER ( www.voda.gov.cz ), which is the output of the interdepartmental project. The project administrators are the Ministry of Agriculture and the Ministry of the Environment, in co-operation with the other central water authorities (the Ministry of Defence, the Ministry of Transport and the Ministry of Health) and in coordination with the Ministry of the Interior. The individual ministries use this website to provide interesting information relating to the water sector in the Czech Republic.

The basic idea of the website design is based on the fact that the system in question is decentralised (distributed), with individual applications (records) being operated by the entities which have produced the data. These applications are basically sub-applications using the central services of the access portal, which serves as a “signpost“ to the respective databases. The ministries thus use the uniform, well-arranged and easily accessible applications to present the general public with credible information about Czech waters and in this way contribute to better and earlier awareness of the public as well as to meeting their legislative obligations. With regard to the scope and presentation of the individual applications (records) and navigating them, this system is absolutely unique, even by European standards.

The obligatory records of the WATER Information System of the Czech Republic are also available for downloading. Visitors to the Water management information portal – WATER are free to view selected records containing territory–related information on a detailed digital map. In the final stage the project should enable the individual records to be shared as part of other public administration information systems, thus allowing their operators to use the website map services to include certain parts of the WATER Information System of the Czech Republic in their applications in a different context. They can therefore use such parts without the need to update and copy them.

The main structure of the Water Management Information portal – WATER web site is based on three main bookmarks which also comprehensively illustrate the arrangement of this publication. These bookmarks are:

• Current information • Records of the WATER Information System of the Czech Republic • Information about the project

18 The information presented is also available in English on at www.water.gov.cz .

Selected current information is at the same time available through WAP technology on www.voda.gov.cz/wap .

CURRENT INFORMATION E R R U C 3. Current Information The current information includes ”above-standard” data, currently provided by the river basin administrators, i.e. the River Boards, state enterprises, and the presentation of which is not based on any of the legal regulations of the Czech Republic currently in force.

Flood situations as well as dry periods constitute the largest disaster threats in the Czech Republic. This fact is due to its location on the continental and global scale. Floods cannot be prevented; only their impact on the lives of citizens and their property can be mitigated. The role of the Ministry of Agriculture as the founder of the River Boards, state enterprises, is to act as an intermediary for the general public in the presentation of data collected by the expert watercourse administrators, who monitor the data for their own day-to-day work.

To this end they use up-to-date information which allows the public to have access to continuous information about water level stages and flow rates on watercourses. In flood situations this data allows everyone to build up a picture of the situation which is developing on individual watercourses, find out how fast the flood wave is travelling and how the water level stages on watercourses are increasing or falling. Everything is up-to-date because the data is updated every thirty minutes during the floods. The degree of flood activity is also indicated.

Newly presented information about the current water level stage in the respective reservoir is very important for potential flood wave storage when the flow rates in watercourses are increasing. The current status of the particular capacities in reservoirs is indicated by colour codes, and the presentation of their distribution, including detailed descriptive data and explanatory notes is graphically very well arranged. The current information about water quantity in the reservoir including the values of both the inflow and the simultaneous runoff volumes is thus available in thirty minute intervals, not only in flood situations. In this way the public has access to transparent and complete information regarding operations of major reservoirs.

Other information also published includes data on the volume of precipitation accumulated during the last 24-hour period and measured in one-hour intervals, at almost 180 sites in the Czech Republic. This data is used to inform the public about the level of water saturation in the individual catchment area and its potential

23 impact on the increase in water levels in watercourses. This information is provided by the precipitation gauge stations operated by the Czech Hydrometeorological Institute and by the River Boards, state enterprises.

An integral part of the current information is water quality in selected reservoirs, allowing the monitoring in reservoirs of the quality of surface waters with regard to their trophism. An important indicator defining the quality of water in reservoirs is water transparency, which It indicates the clarity of water stored in a reservoir at a given moment. As well as details temperature and chlorophyl value, the public receives information having a significant impact on the frequency of recreational visits to reservoirs.

Apart from the account of the current information there is also an application dealing with the technical records of watercourse features and properties. This application is a system of extensive technical information about structures and features on watercourses in relation to where they are located on a watercourse. This application is used to make public the basic information regarding dams, gauging stations, weirs, surface water and groundwater abstraction sites, wastewater discharge sites, reservoirs and water quality control hydrometric profiles.

24 3.1. WATER LEVEL STAGES AND FLOW RATES ON WATERCOURSES Water level stages and flow rates on watercourses are based on the selected profiles of stream flow gauging stations in the national monitoring network operated by the Czech Hydrometeorological Institute and of the complementary hydrometric profiles operated by River Boards, state enterprises. These stations measure the water level stage (in cm) and the respective derived flow rate (in m 3.s -1 ).

The presentation shows the degree of flood activity. There are three levels of activity: Flood activity degree I – state of alert; Flood activity degree II – state of danger and Flood activity degree III – state of emergency. River locations for reports of the flood forecasting and warning service (A category profiles) are situated at the sites of the stream flow gauging stations operated by the Czech Hydrometeorological Institute or by watercourse administrators. The measuring stations are fully automated. Some of the reporting river sites (B category profiles) are also located at the sites of the existing stream flow gauging stations. All of these reporting river sites (profiles) have sufficient technical equipment, i.e. with a staff gauge installed (in most stations together with graphical or digital recording equipment) and a discharge/station rating curve specified for each profile. Hydrological observations in these stations are mainly conducted by volunteer observers of the Czech Hydrometeorological Institute and to a smaller extent by operation personnel of the River Boards, state enterprises. Auxiliary reporting river sites (C category profiles) are operated by municipalities, for a specific purpose, or by the owners of the property exposed to the flood threat, and are of local importance. They can form the basis of local flood warning systems and thus warn the population, especially of the course of storm floods on small watercourses. An integral part of this application is also the presentation of another hydrological extreme, i.e. the indicator of “drought“ which is – unlike floods – characterised by a stream flow recession below a certain limit. In the application it is characterised by a mean daily discharge achieved or exceeded 355 days a year on average.

Monitored indicators: • Water level stage (cm) • Stream flow rate (m 3.s -1 ) • Flood activity degrees 3 -1 • Drought indicator Q 355 (m .s )

Main benefits: • Timely information about flood or drought threat • Regular monitoring and updating • Select language option 25 Map of the Czech Republic

27 28 3.2. WATER LEVELS IN RESERVOIRS The Water levels in Reservoirs application presents information in form of the quantities measured in the reservoirs administered by the River Boards, state enterprises, updated at thirty minute intervals.

The values, which are regularly measured and recorded at the 101 reservoirs on the Czech Republic administered by the River Boards, state enterprise, include water levels, air temperature and precipitation amount. In addition, for some of the reservoirs the application presents the values reflecting the inflow of water into the reservoir, or, as the case may be the water runoff from a reservoir, which were either measured, or derived from a particular hydrological balance.

Clearly arranged and up-to-the minute information about the current water level in reservoirs is presented through differentiating the individual areas in the reservoir. The water level in reservoirs may thus be at the level corresponding to the usable/effective storage capacity, the manageable flood storage capacity or may even exceed the maximum water level. For each of the reservoirs besides this data there is a clearly arranged diagrammatic chart showing the distribution of the individual areas in the water reservoirreservoir.

Monitored indicators: • Water level in the reservoir (in m above mean sea level) • Volume of water in the reservoir (mill. m 3) • Water inflow and runoff (m 3.s -1 ) • Precipitation (mm) • Air temperature (°C)

Main benefits: • Timely information about flood threat • Regular monitoring and updating • Clearly arranged graphic form • Comprehensive information about operation on large reservoirs which the River Boards, state enterprises, have the right to manage

31 32 3.3. PRECIPITATION Current information about one-hour precipitation amounts and air temperatures is generated by precipitation gauge stations in the national monitoring network operated by the Czech Hydrometeorological Institute, in climate stations and on hydraulic structures administered by the River Boards, state enterprises. The data is received continuously from almost 180 sites in the Czech Republic.

This application makes it possible to obtain an overview of one hour precipitation amounts measured during the last 24 hours and daily precipitation amounts measured during the last seven days from the automated precipitation gauge stations. When temperatures are above freezing point, the automated precipitation gauge station network shows the rainfall amount for the previous hour. The temperatures are “negative“ when falling snow is melting, and the apparatus measures the amount of water it contains. In a standard situation the data is updated every hour; in a flood threat situation and during floods the updating frequency is higher.

Precipitation measurement in automated precipitation gauge stations was included in the monitoring and control system used by the water management operational centres of the River Boards, state enterprises, with the specific aim of improving the forecasts of the subsequent flow rate evolution, in particular on the upper stretches of watercourses when using the HYDROG or AQUALOG forecasting rainfall- runoff mathematical model.

Monitored indicators: • One hour precipitation amounts during the last 24 hours (mm) • Daily precipitation amounts during the last seven days (mm) • Air temperature (°C)

Main benefits: • Timely information about precipitation amounts and their subsequent impact on flood threats • Regular monitoring and updating • In a ”negative“ temperature situation the apparatus measures the amount of water contained in the melting snow

35 36 3.4. WATER QUALITY IN RESERVOIRS In terms of trophism, the quality of water in reservoirs gives information about surface water quality in selected reservoirs administered by the River Boards, state enterprises. Monitoring water transparency and other important indicators affecting water quality in reservoirs (e.g. chlorophyl-a) is carried out only during the growing season, i.e. from April to October each year. Water temperature is measured all the year round, every day at 7 a.m. several centimetres below water level, near the dam. It is an appropriate indicator of both the ice occurrence and ice drift, and in reservoirs suitable for recreation it indicates bathing conditions. It is measured manually by a calibrated thermometer. The water transparency is measured by means of a Secchi disk once or twice a week at the same time of day and subject to local conditions, either from a boat or another suitable place close to the water level. Samples for measuring chlorophyl-a are taken in the specified place (mainly the location specified for measuring water temperature), using a special sampling device, once a month. The identified concentration value of this substance in water allows high accuracy evaluation of the level of algae and cyanobacteria presence at the measurement site. For selected reservoirs a number of indicators are presented using of ReViewer software, allowing evaluation of the presented data in colour and comparing it with the previous calendar year. The indication of substance distribution is derived from a determination carried out on vertical lines which are plotted at the reservoirs on a permanent basis. The position of these vertical lines is marked with a yellow ring in the reservoir diagrams. By activating this symbol on the screen the distribution of selected parameter values in the given cross section is displayed. Activation of any point on the water level displays in the chart the spatial distribution of the selected parameter in the longitudinal profile of the reservoir.

Monitored indicators: • Temperature (°C) • Transparency (m) • Chlorophyl-a ( g.l -1 ) • pH value, dissoµlved oxygen etc.

Main benefits: • Monitoring on public water supply reservoirs and reservoirs used for recreation and fishing • Regular monitoring and updating • User-friendly graphical evaluation

39 40 3.5. CENTRAL TECHNICAL REGISTRY OF WATERCOURSE FEATURES AND PROPERTIES The register is a system of extensive and wide-ranging technical information about structures and features on watercourses in terms of where the structures are located.

The technical register uses the records in the basic watercourse register including the watercourse parts and stretches according to their hydrological designation and the breakdown, which is based on their categorisation. The system functions provide a unique data link to the watercourse structural model, enabling at the same time a link to the mapping data. For this reason the system currently makes use of the public administration portal mapping services.

All the technical information about the structures and features on watercourses published on the portal is jointly registered by all of the five River Boards, state enterprises. The presentation currently includes only selected features, which are published on the basis of an agreement with the representatives of all the River Boards, state enterprises. These selected features currently are: dams, measuring/gauging stations, weirs, surface water and groundwater abstraction sites, wastewater discharge sites, reservoirs and water quality control hydrometric profiles.

Monitored indicators: • Uniform standard for River Boards, state enterprises • Basic information about selected structures and features on watercourses

Main benefits: • Option of selecting structures and features by the respective watercourse and river kilometres • Option of selecting and view the technical register data based on competence of the River Boards, state enterprises • Option of browsing the structural model of watercourses • Regular updating

43 44 3.6. MOBILE INTERNET Mobile equipment offers a unique possibility of continuous information about important up-to-date events literally anywhere and at any time. If you need to current information quickly about the quantity of water in our watercourses and reservoirs and you do not have a computer with an Internet connection close at hand, you can access not only this but also other information through mobile equipment (mobile phone, handheld devices etc.) supporting WAP technology.

For this very reason the Ministry of Agriculture, in co-operation with the River Boards, state enterprises, ensures the presentation of the most important information also by means of this technology. Therefore, the general public can currently find on the relevant WAP sites current information about the volume of water and flow rate in watercourses, water level stage in reservoirs and precipitation volume, including the most important contacts to the particular River Boardstate enterprise.

This service is of invaluable significance especially during floods, when the citizens, mayors of municipalities or as the case may be the members of the individual flood protection commissions can monitor directly in the field how the flood situation is evolving. www.voda.gov.cz/wap

W S RECORDS OF THE INFORMATION D M R E O T C S E SYSTEM WATER IN THE CZECH REPUBLIC Y R S 4. Records of the Information system WATER in the Czech Republic The records of the WATER Information System in the Czech Republic comprise a detailed set of “mandatory” data based on the provisions of the Water Act. Through the provisions of Sections 21 and 22 the Act imposes on the Ministry of Agriculture and the Ministry of the Environment the duty to keep appropriate records as a part of the public administration information system according to the particulars resulting from Act No. 365/2000 on Public Administration Information Systems, as amended.

To this end, in 2004 the Ministry of Agriculture, in co-operation with the Ministry of the Environment, issued Public Notice No. 391/2004 on the scope of data contained in records on surface water and groundwater status and on the method of processing, storing and presenting this data in public administration information systems. The Public Notice specifies in detail an overview of all the records under the responsibility of the above ministries and provides an account of all data registered under this Public Notice, which is processed, presented and stored in the public administration information system. In addition to the responsibilities of the respective ministries for the above records, the Public Notice includes also the direct responsibility of the relevant qualified entities (under the jurisdiction of the individual water authorities) responsible for collection and records of data in the scope of their operation information systems.

The provisions of Section 19 of the Water Act at the same time stipulate that water authorities are obliged to store in the public administration information system selected data from the records they keep on their decisions, as specified by Public Notice No. 7/2003 on Water Management Records, as amended, and to transfer this data to the Ministry of Agriculture. The records of the final and conclusive administrative decisions issued by water authorities are also included in the content of this bookmark.

Thanks to the information contained in this bookmark, which is presented by the Ministry of Agriculture, the public can have an overview of the responsibilities for watercourse management and maintenance, and an overview of reservoirs and surface water quality, permitted abstractions and discharges, records of the river basin districts, sources of drinking water, land improvements and reclamation or water management records. The information provided includes well-arranged, easily accessible and comprehensible data which is interesting and very important for all citizens of the Czech Republic.

49 50 4.1. WATERCOURSE REGISTER The watercourse register comprises sub-records kept by the individual watercourse administrators – the River Boards, state enterprise the Agricultural Water Management Authority (including data concerning natural persons and legal entities), Forests of the Czech Republic, state enterprise, the National Parks administration bodies and the Ministry of Defence, which is responsible for military districts. The watercourse layer, the “Central Watercourse Register/Records (CEVT)”, is the basic structural and linking register, and is used for additional territorial links to features of other records and for subsequent updating watercourse layers in the related public administration information systems. In the first stage of the process of compiling this register the individual watercourse administrators processed and updated the original register produced by the T.G. Masaryk Water Management Research Institute, a public research institution, using the Basic Water Management Map of the Czech Republic, on a 1:50,000 scale. The subject matter of the modifications made by the watercourse administrators at this stage of work was to check the administration and management issues and to add a unique identifier number to the respective watercourse (CEVT IDVT). In the year 2007, this data was matched with the National Map of the Czech Republic, on a 1:10,000 scale (ZABAGED), for updating and specifying the registered data in more detailed form, including the transfer and implementation of the watercourse layer, on a scale of 1:10,000, in the operation information systems of all the River Boards, state enterprises. Identifying watercourses administered and managed by the River Boards, state enterprises, was also an integral part of these activities. At present the WATER information system in the Czech Republic comprises both the original records of watercourses, on a scale of 1:50,000, and the newly compiled records, on a 1,10 000 scale (note: information about the administration is currently presented only for watercourses administered and managed by the River Boards, state enterprises).

Monitored indicators: • Name of the watercourse • Watercourse administrator • Identifier number of the watercourse • Territorial identification • Length of the watercourse

Main benefits: • Continuous updating of data (administration and geometry of watercourse centre lines) • Easy search based on the selected parameters (name of the watercourse, the number of hydrological order – NHO etc.)

65 66 4.5. REGISTER OF SURFACE WATER QUALITY IN COMPLEMENTARY HYDROMETRIC PROFILES OPERATED BY RIVER BOARDS, STATE ENTERPRISES This register is based on data on the characteristic values of surface water quality calculated from the values measured by river basin administrators in the complementary watercourse profiles.

Samples taken from all control sections are analysed to determine the general, physical and chemical indicators of water quality. The surface water quality measurement results are further processed. To be able to provide general information and especially to compare water quality at various places and different times, the quality of flowing surface waters is classified into five water quality categories according to the Czech national standard ČSN 75 7221 (Water quality – Classification of surface water quality):

Class I (unpolluted water) – water suitable for drinking water supply purposes, food processing industry, open air swimming pools and bathing places and salmonide fish farming. Unpolluted water is of a large landscape enhancement value. Class II (slightly polluted water) – suitable for drinking water supply purposes, fish farming, water sports and industry. Slightly polluted water is of a good landscape enhancement value. Class III (polluted water) – water suitable only for water supply to industry and only appropriate for drinking water supply if no other more suitable source is available. Polluted water is only of a low landscape enhancement value. Class IV (heavily polluted water) – as a rule water only for certain limited purposes. Class V (very heavily polluted water) – as a rule, water unsuitable for any purpose.

Monitored indicators: • Water temperature (°C) • Ammonia and nitrate nitrogen (mg.l -1 ) • Water reaction • Total phosphorus (mg.l -1 ) • Electrolytic conductivity (mS.m -1 ) -1 • Biological oxygen demand – BOD 5 (mg.l ) -1 • Chemical oxygen demand by dichromate – COD cr (mg.l )

Main benefits: • Territorial identification of hydrometric profiles used for quality monitoring of surface water • The data is stored for the previous calendar year by June 30 of the relevant calendar year at the latest • Classification of waters in water quality classes according to the relevant standard

69 70 4.6. REGISTER OF SURFACE WATER QUALITY IN THE HYDROMETRIC PROFILES OPERATED BY THE AGRICULTURAL WATER MANAGEMENT AUTHORITY This register is based on the data on characteristic values of surface water quality indicators, which are calculated from the values measured in the hydrometric profiles of surface water status and quality monitoring, operated by the Agricultural Water Management Authority on minor watercourses.

Hydrometric profiles on minor watercourses are monitored as a part of the monitoring process in the national water quality monitoring network, operated by the Czech Hydrometeorological Institute and as part of the point pollution source monitoring process.

Monitoring conducted by the Agricultural Water Management Authority keeps under review the general physical, chemical and biological indicators allowing identification at an early stage of minor municipal and agricultural sources of pollution and thus a warning against the possibility of area pollution. The agents monitored include also selected heavy metals and some specific organic substances.

The monitoring, which should in the final instance result in constant improvement of water quality, meets the current requirements for surface water quality monitoring laid down by both the state administration and the European Community for implementation of the individual directives and regulations.

Monitored indicators: • Water temperature (°C) • Water reaction • Electrolytic conductivity (mS.m -1 ) -1 • Biological oxygen demand – BOD 5 (mg.l ) -1 • Chemical oxygen demand by dichromate – COD cr (mg.l ) • Ammonia and nitrate nitrogen (mg.l -1 ) • Total phosphorus (mg.l -1 )

Main benefits: • Territorial identification of hydrometric profiles used for surface water quality monitoring • The data is stored for the previous calendar year by June 30 of the relevant calendar year at the latest • Classification of waters in water quality classes according to the relevant standards 71 Map of the Czech Republic

73 74 4.7. REGISTER OF SURFACE WATER AND GROUNDWATER ABSTRACTIONS, DISCHARGE OF WASTE WATERS AND MINE WATERS AND STORAGE OF SURFACE WATERS IN RESERVOIRS This register is based on the data which must be reported for water balance assessment purposes. The water balance assessment comprises the hydrological balance, which compares the increase or decrease in water quantities and changes in water resources under a certain time period, and the water management balance, comparing the requirements regarding water abstractions and discharges with the available water capacity of the exploitable water resources in terms of water quantity and quality as well as in terms of their environmental status.

The data is provided by surface water or groundwater consumers, by those who use natural medicinal sources, natural mineral water sources and waters which are classified as reserved minerals. The data is also provided by consumers discharging wastewaters or mine waters into surface waters or groundwater in volumes exceeding 6,000 m 3 in a calendar year or 500 m 3 in a calendar month, and by those with a permitted volume of retained surface water impounded by the hydraulic structure in the watercourse or surface water accumulated by the hydraulic structure, exceeding 1 million m 3.

The whole application presenting information about water abstractions, discharges and accumulation is based on the data collected by the individual river basin administrators, to whom this data is reported once a year.

Monitored indicators: • Selected reported data by the type of water use • The date of issue and duration of the permission for water use

Main benefits: • Territorial identification of the permitted water use in the given area • The data is stored for the previous calendar year by June 30 of the relevant calendar year at the latest • Permitted parameters and purpose of the water use

82 4.9. REGISTER OF THE SURFACE WATER AND GROUNDWATER SOURCES USED AS DRINKING WATER SOURCES The register of surface water and groundwater sources provides information about all the sources which are used as sources of drinking water in the Czech Republic. The data on drinking water sources originates from the assets register on water treatment plants both with and without water treatment technology. Under the provisions of Section 5 para 3 of Act No. 274/2001 on Public Water Supply and Sewerage Systems and on amendment to certain laws (Water Supply and Sewerage Systems Act) as amended the owners are obliged to submit selected data from the assets records and operational records concerning water supply networks or sewerage systems to the relevant water authorities. Under the current legal regulations the due date for handing over the data is set to February 28 each year at the latest. Water authorities then pass on the data in accordance with the provisions of Section 5 para 4 of the Water Supply and Sewerage Systems Act to the Ministry of Agriculture by April 30 of the calendar year at the latest. The scope and the method of keeping the assets records are stipulated by Public Notice No. 428/2001, which implements the Water Supply and Sewerage Systems Act. Records of drinking water sources are kept within the scope of the data specifying their territorial identification, their names and number code of the land registry area, the raw water category and identification number of the water abstraction. This data is processed and transferred into the public administration information system by the Ministry of Agriculture.

Monitored indicators: • Name of the source • Name and identification number of the water treatment plant • Name and code of the land registry area where the water treatment plant is located • Raw water category • Identification number of water abstraction

Main benefits: • Records on the drinking water sources which are used • Localisation of water treatment plants and sources • Well-arranged structure of surface water and groundwater sources used as drinking water sources according to the division of the state administration in the Czech Republic • Information on the requirements for raw water quality including the methods of treatment of water to drinking water standards • Continuous updating 83 Map of the Czech Republic

85 86 4.10. REGISTER OF HYDRAULIC STRUCTURES FOR WATER MANAGEMENT LAND IMPROVEMENT The record dealing with land improvement and land reclamation is based on the data collected by the Agricultural Water Management Authority. The Agricultural Water Management Authority is an organisational component of the state, established by the Ministry of Agriculture for the purpose of maintaining and administering minor (small) watercourses in agricultural landscape and the main drainage facilities. Its nationwide area of responsibility covers five river basin districts – according to the area of responsibility of the River Boards, state enterprises.

Records on hydraulic structures designed for water management land improvements as defined by the provisions of Section 55 of the Water Act are kept within the scope of the data specifying their territorial identification and the data laid down by the Public Notice of the Ministry of Agriculture No. 225/2002 on the detailed determination of structures designed for water management improvements of land and the parts thereof, the method and scope of their upkeep, with the exception of data on the name, surname, place of permanent residence and birth registration number (personal identification number) of a natural person.

Structures designed for water management land improvements are regarded as structures which are used for irrigation and drainage of land as well as structures designed to protect the land from water erosion.

Structures designed for drainage of agricultural land are divided into the main and subsidiary drainage facilities. In subsurface drainage systems subsidiary drainage facilities mean lateral and main drains, drainage wells and outlets; in surface drainage systems they comprise drainage ditches and associated (connected) structures. Subsidiary drainage facilities are an integral part of the land in question.

Monitored indicators: • Land improvements and reclamation systems in the Czech Republic

Main benefits: • Well-arranged identification of land improvements and reclamation • Continuous updating

89 90 4.11. REGISTER OF SELECTED DATA FROM EFFECTIVE DECISIONS OF WATER AUTHORITIES These records of selected data constitute a unique database of effective decisions issued by the water authorities and of the information selected from these decisions which may be used by the respective water authorities in their day-to-day practice and by both the expert and lay public when planning their water management activities. At the same time the information can also be used by other administrative bodies, legal entities or natural persons who need to know the scope and the amount of water management activities which have been so far permitted. In terms of the factual content this information includes permits for water use (water abstraction, accumulation of water, discharge of wastewaters etc.), permits for certain activities (planting of trees or shrubs in flood plain areas to an extent which is affecting runoff conditions, returning a watercourse to its original channel etc.), permits for discharge of wastewaters containing especially dangerous harmful substances into sewerage systems, building permits for hydraulic structures as well as changes, cancellation and termination of permits for water use, decisions aimed at protection of water resources, territory and hydraulic structures, other measures taken by the water authority, and occupancy permits allowing hydraulic structures to be put into operation. The individual decisions are in these records sorted by the water authorities, in terms of the monitored period and the date of their coming into force. Every decision is specified by its reference number, its brief description, the date it came into force and its classification according to the factual focus or subject matter (e.g. building permit for hydraulic structures, water use). The classification uses eight colour tones for making it easier to use. Each decision includes as an attachment also its electronic form.

Monitored indicators: • Selected data from the effective decisions of water authorities • Decisions issued by water authorities in electronic form • Quantitative overview of the administrative duties of water authorities

Main benefits: • Support for carrying out the public administration’s duties • Data for implementation of water management objectives • Visualisation of administrative districts and the hierarchy of water authorities • Option of searching by the factual aspects of the decision • Continuous updating
