沙河漯河上游三面环山,年雨量700~1000mm,且分配极不均匀,60%集中在6~8月份,有的年份汛期雨量集中为1~2次大暴雨,是我省常遇暴雨中心地带,是沙颍河洪水发源地,极易造成灾害。沙河漯河上游主要河道共三条,即:沙河干流、北汝河、澧河,流域面积分别为3713km~2、6080km~2、2787km~2。建国以来,根据“蓄泄兼筹”的治水方针,在沙河干流上游修建了昭平台、白龟山两座梯级水库;在支流澧河上修建了孤石滩水库,在沙、澧河之间低洼易

The distribution is extremely uneven. 60% of the rainfall is concentrated in June to August. In some years, rainfall in rainy season is concentrated in 1 or 2 heavy rainstorms, It is the birthplace of Shaying River flood and can easily cause disasters. The upper reaches of the Shahe River Luohe a total of three main rivers, namely: the main Shahe, North Ruhe, Bahe, drainage area of 3713km ~ 2,6080km ~ 2,2787km ~ 2.
