When withdrawal takes place from a permanently flowing watercourse, the minimum residual flow must be as follows:up to a flow rate Q347 of 60 l/s 50 l/s    and for each further 10 l/s of flow rate Q3478 l/s,for a flow rate Q347 of 160 l/s 130 l/s    and for each further 10 l/s of flow rate Q347 4.4 l/s more,for 500 l/s of flow rate Q347280 l/s    and for each further 100 l/s of flow rate Q34731 l/s more,for 2,500 l/s of flow rate Q347900 l/s    and for each further 100 l/s of flow rate Q34721.3 l/s more,for 10,000 l/s of flow rate Q347 2,500 l/s    and for each further 1000 l/s of flow rate Q347 150 l/s more,from 60,000 l/s of flow rate Q34710,000 l/s.The minimum residual flow calculated according to paragraph 1 above shall be increased if the following requirements are not complied with and cannot be complied with as a result of other measures:a.  The prescribed water quality of the surface waters must be maintained in spite of the water withdrawal and existing waste water discharges.b.  Groundwater resources must continue to be replenished such that the drinking water supply dependent on them remains available to the required extent and the water balance of soils used for agriculture is not substantially impaired.c.  Rare habitats and biocoenoses which depend directly or indirectly on the type and size of a body of water must either be maintained or where possible be replaced by others of a similar value unless overriding reasons prevent this.d.  The depth of water necessary for free fish migration must be maintained.e.  In the case of watercourses with a flow rate Q347 of up to 40 litres per second below an altitude of 800 metres above sea level which serve as spawning grounds or habitats for juvenile fish, the continuation of these functions must be guaranteed.

Tar prelevaziuns d’aua or d’auas currentas cun deflussiun permanenta sto la quantitad d’aua restanta importar almain:fin ad ina quantitad da deflussiun Q347 da 60 l/s      50 l/s    e per mintga 10 l/s che questa quantitad è pli gronda        8 l/sper ina quantitad da deflussiun Q347 da 160 l/s    130 l/s    e per mintga 10 l/s che questa quantitad è pli gronda     4,4 l/s dapli,per ina quantitad da deflussiun Q347 da 500 l/s    280 l/s    e per mintga 100 l/s che questa quantitad è pli gronda      31 l/s dapli,per ina quantitad da deflussiun Q347 da 2500 l/s    900 l/s    e per mintga 100 l/s che questa quantitad è pli gronda   21,3 l/s dapli,per ina quantitad da deflussiun Q347 da 10 000 l/s 2 500 l/s    e per mintga 1000 l/s che questa quantitad è pli gronda     150 l/s dapli,a partir d’ina quantitad da deflussiun Q347 da 60 000 l/s10 000 l/s. La quantitad d’aua restanta calculada tenor l’alinea 1 sto vegnir augmentada, sche las suandantas pretensiuns n’èn betg ademplidas e na pon betg vegnir ademplidas tras autras mesiras:a. la qualitad prescritta per las auas da surfatscha sto vegnir mantegnida malgrà la prelevaziun d’aua e malgrà inducziuns existentas d’aua persa;b. las resursas d’aua sutterrana ston vegnir alimentadas er vinavant uschia, che la producziun d’aua da baiver è pussaivla en la dimensiun necessaria e che la bilantscha d’aua da terrens utilisads da l’agricultura vegn disturbada mo minimalmain;c. ils biotops rars e las biocenosas raras che dependan directamain u indirectamain dal tip e da la grondezza da l’aua ston vegnir mantegnids u ston – sch’i na s’opponan nagins motivs stringents – vegnir remplazzads sche pussaivel tras biotops e tras biocenosas da medema valur;d. la profunditad da l’aua ch’è necessaria per ch’ils peschs possian migrar libramain sto vegnir garantida;e. en auas currentas cun ina quantitad da deflussiun Q347 fin a 40 l/s, ch’èn situadas sut 800 m sur mar e che servan als peschs sco plazzas da fregar u sco lieus per trair si lur giuvens, ston questas funcziuns esser garantidas er vinavant.
