Note
Die Proben wurden am Ufer entnommen. Die Umgebung besteht dort aus vielen Bäumen, Büschen und Pflanzen. Sehr vertreten ist dort die Brennnessel. Das Wetter war trüb, verregnet und bewölkt wodurch das mittel hohe Gras feucht war. Das Wasser war braun und trüb. Zusätzlich war an der Proben Entnahme Stelle eine starke Strömung.
