干流概况

濛江发源于贵州省黔南布依族苗族自治州长顺县马路乡吴家堡,向北流经石燕水库和马路乡后折向西南,进入安顺市西秀区,经革寨水库和杨武布依族苗族乡后,于水落洞伏流进入紫云县境内,于粟树关复明流。经天星桥、马落坑伏流才,穿过黄鹤营旅游区的彩色溶洞,与洞边复明流。折向西至猫营镇打扒河村转南,于板当镇新场村折向东南。濛江新场以上河段为上游,也称座马河,河长65千米,落差375米,流域面积786平方千米。

干流自新场东南流至板当镇小河边左纳板当河后转西南流,右纳小牛场河后折向东,至梨树脚转东南流,至水淹坝伏流至长顺县下洞复明流,沿紫云和长顺两县边界东南流,进入罗甸县,于双河口左纳涟江。紫云县新场至罗甸县双河口为中游,也称格凸河,河长91千米,落差565米,流域面积4037平方千米。

濛江下游干流自罗甸县双河口转西南流,在木引乡折向东,至石门坎水电站转东南流,最后至双江口注入红水河。下游河长97千米,落差268米,流域面积3910平方千米。[1]
