Statistics of reported catches 2013

Finally we had a normal summer again with nice weather most of the time and just a few periods with a little rain. The fishing conditions were therefore good and very good most of the season. Because of the nice weather in July (only three rainy days) this month for the first time was better than June.

32 % of the reported grayling were +35 cms. 19 graylings were between 45 and 49 cms and 3 graylings were +50 cm! This is the first season we have had reported graylings + 50 cms. In the year 2000, when the fly zone was established, only 10 % of the graylings were +35 cms so the development has been incredible.
