The time period for gate opening is usually determined by specific gate operation regulations, which are generally divided into the following situations:
Natural opening of gates: For gates in natural rivers, such as seasonal rivers, the opening time of gates may be related to the high and low water periods of the river, and is generally performed after the flood season or before the dry season.
Manual gate opening: For reservoirs or water conservancy hubs, the gate opening time will be determined based on the reservoir dispatch plan and agricultural irrigation, power generation, urban water supply and other needs. Specific times may be as follows:
- Irrigation Period: Usually during the season when crops require irrigation, such as spring or summer.
- Power generation period: On the premise of ensuring downstream water supply, the reservoir will open and generate electricity according to power demand.
- Water Supply Period: A period when urban water supply demand is large, such as the high temperature period in summer or the cold period in winter.
- Tourism Period: During the peak tourist season, some scenic spots may arrange to open gates to increase the landscape effect.
- Irrigation Period: Usually during the season when crops require irrigation, such as spring or summer.
For the specific gate opening time, you need to consult the relevant departments or check the official announcement.
