The article considers turbidity in a water storage basin during dredging in water extraction zones for household and drinking needs. Turbidity zones are calculated with the help of a math model based on the solution to the shallow water equations in the advective diffusion equation for impurity distribution. The model was verified on the basis of a field experiment in the Kuibyshev water storage basin. The data on additional turbidity in the water extraction zone collected with the help of a suction dredge shows that the turbidity is higher than the maximum allowed concentration (MAC), but when a crane boat is used, the calculated value does not exceed MAC.
