15, the Baotu Spring water level is 28.19 meters, approaching yellow warning line 28.15 meters. In order to keep the spring water spewing, 15 days later, the hushushan reservoir was officially launched to fill the source of recharge, and the daily discharge of water was 200 thousand cubic meters. It is expected to continue for a month or so. It is understood that the replenish source on the one hand, in order to protect springs, on the other hand, it can also supplement irrigation water for the 600 thousand acres of farmland in the southern mountains.
15 days, the storage dam of the reservoir is opened. As the gate is lifted slowly, the water of the reservoir is spewed out, and together with the huge water flow in the reservoir water cave, the reservoir is remitted into the Yufu river. After entering the Yufu river for about 4 kilometers, it will enter a strong seepage zone about 2 km and form groundwater through the seepage zone. Liu Guang, deputy director of Ji'nan hushushan reservoir management office, said that according to the requirements of the flood prevention department of Ji'nan, from 15 days, the hushushan reservoir was officially launched.
it is understood that, according to the "Ji'nan city to maintain the spring water spray emergency plan", the Baotu Spring water level to 28.15 meters, will be issued a yellow warning, starting emergency plans. On the 15 day, the water level of Baotu Spring was 28.19 meters, 19 centimeters lower than that of 28.38 meters in the same period last year, and it was close to the yellow warning line 28.15 meters. "In fact, in order to ensure the continuous spewing of the spring water and slowing down the trend of water level decline, from March 21st, the reservoir has begun to release water into the Yufu River, and the water is leaking and recharging the source through the river. At present, 4 million 400 thousand cubic meters of water have been released." According to the relevant person in charge of Ji'nan Water Conservancy Bureau, according to the downward trend of water level, the amount of water discharge may increase, and it is expected that the water will continue to drain for about a month.
it is understood that since the beginning of 2003, the hushushan reservoir began to supplement groundwater by recharge and replenishment. "Under the influence of spring irrigation water, production and living water and less spring precipitation, the decline of groundwater level is faster, and the opening and releasing of water is about one month earlier than last year." Ji'nan Water Conservancy Bureau responsible person said, in addition to the source of recharge can save spring, but also for the southern mountain area of 600 thousand acres of farmland supplementary irrigation water source.
