调蓄、灌溉,是中小型水库的两大功能,所以,开春伊始,水库便开闸加大放水量,灌溉农田。从此,水库的水位不断下降,到了七八月间,水位降到当年的最低点,有的水库在汛期到来之前,水位几乎降到了死库容。这个时期,虽然水面大大减小,鱼的数量比值相对增多,但却是一年当中最难钓的一个时期。由于水位的大大下降,各种大中型鱼类都游到水库水体最深、也是最安全的大坝一带栖息,一天的大部分时间是在这里度过的。不到 Regulation and storage, irrigation, small and medium-sized reservoirs are two major functions, so the beginning of the spring, the reservoir will open the gate to increase drainage, irrigated farmland. Since then, the reservoir water level continues to decline, in July and August, the water level dropped to the lowest point of the year, and some reservoirs in the flood season before the arrival of almost dead water level. During this period, although the water surface was greatly reduced and the ratio of the numbers of fish relatively increased, it was the hardest time to catch during the year. Due to the drastic drop in water level, all kinds of large and medium-sized fish swim to the deepest and deepest part of the reservoir, where they live most of the day. Less than
