淮河入江水道建于1969年,江苏省境内的115公里大堤由于施工时,受财力、物力所限,不少工程没有做足标准,质量粗陋。虽多次行洪,最多年份不过6480流量,且时间不长,对它是否能达到设计的行洪能力无把握。1991年6月中旬起,迫于汛情水情,以8000流量的超大流量行洪,先后持续10天时间,7月18日行洪达8900流量,金湖水位最高时11.69米,达到设计行洪10000流量的理论水位。行洪时间之长,流量之大,水位 The Huaihe River waterway was built in 1969. Due to the construction of the 115-kilometer levee in Jiangsu Province, due to limited financial and material resources, many projects failed to meet the standards and the quality was poor. Although many floods, but up to 6480 years of traffic, and not long time, it is not sure whether it can achieve the design of flood control capacity. From mid-June 1991, forced flood conditions, floods with 8000 large flow of traffic, has lasted 10 days, July 18 Hongxing reached 8900 traffic, the highest water level of 11.69 meters, reaching the design line flood 10000 theoretical water level flow.
