Table 9.1.   Number of hours when water samples were taken and the percentage of time sampled at the stream station in the Odderbæk catchment. The table also shows mean daily discharge during each quarter.   Tabel 9.1.   Antallet af timer i de enkelte kvartalerne hvor der er udtaget vandprøver og beregnet transport af pesticider. Endvidere er tidsrummet dækket med prøvetagninger vist relativt sammen med den gennemsnitlige vandføring ved den vandløbsstationen i Odderbæk oplandet.   Quarter 2nd 3rd 4th 1999 1st 2nd 3rd 2000 Total hours sampled at the stream station 122.0 28.0 98.0 248.0 76.0 78.0 30.0 184.0 Percentage of time sampled 5.6% 1.3% 4.4% 3.8% 3.5% 3.5% 1.4% 2.8% Mean discharge at the stream station 94 l/s 65 l/s 103 l/s - 165 l/s 78 l/s 55 l/s -
