Abstract
In this study, submerged plant species were investigated in the part of river Kızılırmak passing through Avanos town (Nevşehir) between March 2010 and December 2010. Aquatic macrophytes were sampled by three replicates once a month from four stations. .Furthermore, water depth, Secchi depth, water temperature, dissolved oxygen, pH and conductivity were measured in situ.The dominant submerged plant in the research area was identified as Stuckenia pectinata (L.) Börner (Sago Pond Weed), Another submerged plant which existed rarely was Ceratophyllum submersum. The underwater plant biomass was increased from March, reached its highest level as 1086 dry weight/ m2 in November and the average plant biomass was estimated as 720,9± 287,9 dry weight/ m2. Throughout this study, the average water depth, Secchi depth, water temperature, dissolved oxygen, pH and conductivity were measured as 2,21± 0,45 m, 0,90 ± 0,19 m, 10,19 ± 3,33 °C, 12,45 ± 1,0 mg/l, 8,01 ± 0,3, 1178 ± 67 µS/cm, respectively. The modified stream course which was occurred after the dam construction in Kızılırmak River could be the main reason of the excessive growth of Sago Pondweed.
