* At the upstream and downstream of the spillway structures (if the water level at the downstream is higher than the cap sill level)
* During the operation of the suction pipe downstream of the turbine.
The designs of the Stoplog covers are generally the same as the sliding covers. These types of closures do not include any wheels (without guide wheels) or rollers, except in some rare cases where sloping slots or against flow closures are required. According to the sealing height in the design, Stoplog covers can consist of more than one piece.
