Abstract :This paper aims to identify the benthic macroinvertebrate fauna and some physicochemical char-acteristics of Kanak Dam Lake located in Şarkışla, Sivas. For this, water and sediment samples were taken from 4 stations of the lake between August 2016 to July 2017 at monthly intervals, and a detailed physicochemical analysis was carried out on these samples. While the identification of benthic macroinvertebrates was made to the lowest possible taxa insert ignore into journalissuearticles values(species, genus or families);, some physicochemical characteristics of the lake water such as temperature, pH, electrical conduc-tivity, dissolved oxygen, SO4, PO4, NO3-N, NO2-N, Mg, Ca, total hardness, salinity and Cl levels were determined using various titrimetric and spectrophotometric methods. As a result, a total of 30 taxa were identified and were classified as Oligochaeta, Chironomidae, Gastropoda and other Insecta insert ignore into journalissuearticles values(Ephemeroptera, Trichoptera, Hemiptera insert ignore into journalissuearticles values(adult);, Odonata, Plecoptera and larval Coleop-tera);. All the identified taxa were determined as the first records for the lake. While the tempera-ture, pH, electrical conductivity, dissolved oxygen, chloride and sulfate levels were found to have the first class quality according to Turkey’s water control regulations the NO3-N and NO2-N levels in the lake were found to have the second and third class water quality, respectively. The total hard-ness of the lake water was found to be at lighthard water quality The Shannon Weiner diversity in-dex for macrobenthic fauna of the dam lake was found to be 0.64 on average. The sampling sta-tions and months were evaluated also statistically by using the Bray-Curtis Cluster Index in terms of the distribution of the benthic macroinvertebrates and physicochemical parameters.
