Operation of the pond and dams includes activities for the supervision and maintenance of the dam and spillway structures, their repair and activities for the improvement of the pond area.

The main types of damage are water overflow over the dam crest; water filtration through a dam; destruction of a dam by a breakwater; damage to drainage structures.

Overflow of water over the ridge is observed during very large floods or due to the unpreparedness of spillway structures to handle the flood. To prevent water overflow, spillway structures must be cleared of snow, ice, and debris in the spring before the flood. In case of large floods, when the spillway structures do not have time to discharge water, in order to eliminate the overflow of water, it is necessary to build a temporary drainage canal with water drainage into the beam below the dam.

Cracks often form in new dams before the soil has completely settled due to freezing in the upper layers and continued settlement of the lower layers, leading to the formation of voids. If a transverse crack forms in the dam, you need to dig a trench 1.5-2.0 m deep 0.5 m below the depth of the crack. For a longitudinal crack, a trench is dug along the crack along its entire length. The crack is filled with the same soil from which the dam is made, in layers of 1 5-20 cm with careful compaction.

Filtration of water through a dam can occur if design or construction rules are violated. To eliminate filtration, it is necessary to increase the base of the dam by widening it on the side of the dry slope or to arrange drainage. If the water filtering through the drainage device is clean, this indicates that the dam is in good condition.

The destruction of the dam by a breakwater is eliminated by securing the wet slope with a stone blind area, concrete slabs, or throwing stones over squares made from willow stakes.

Spillways should be constantly cleared of debris, and in the spring of snow and ice. The most common types of damage to spillway structures is the formation of failures along their walls due to water filtration. Dips behind the walls of culverts should be promptly filled with soil.

In order to avoid the erosion of dams, it is necessary to organize observation and concentrate the necessary materials and mechanisms at the time of flood or flood.

The system of operational measures includes landscaping the area around the pond, restoring damaged turf, and creating tree and shrub plantings (the range of species is selected depending on soil and climatic conditions). On the banks of the reservoir along the water's edge, especially in places where the shore is destroyed by a breakwater, it is advisable to plant shrubby willows. When using a pond to extinguish fires, access roads and platforms are built at the water intake points

Periodically it is necessary to clean the pond from herbaceous aquatic vegetation. Small ponds are cleaned by hand; large ponds are cleaned using special mowers and dredgers. After 20-30 years, having completely freed the pond from water, it is cleaned of vegetation, debris and silt. Water is drained through a drain.
