Daily observations of dynamics of spectral light attenuation (ε, m-1), chlorophyll «a» concentration (C, mg/m3) and water temperature (Т, °C) at different depths of Lake Krasilovskoye (Altai Krai) was conducted in June 2013 and May 2014. The sampling in pelagic part of the lake was carried out every two hours (to estimate ε and Т) and every six hours (to evaluate C). Thereafter, spectral water transparency in the wavelength range of 400–800 nm was measured with a spectrophotometer ПЭ-5400УФ, and the samples of phytoplankton algae were filtered in situ. Summer vertical daily measurements of ε shows that the curve of attenuation dynamics for the bottom layer is in...
