国家水利部副部长刘宁8月12日晚间在鲁甸灾区发布牛栏江堰塞湖后续处置方案。根据方案，将进一步深挖泄流槽，降低溃堰风险；后期，堰塞湖还将改造成具有灌溉、发电、防洪、旅游等综合效益的水利工程。

牛栏江堰塞湖或将改造成综合效益的水利工程

　　牛栏江堰塞湖是云南鲁甸县“8·03”地震中形成的库容达2.6亿立方米的大型堰塞湖，也是灾区目前最大的堰塞湖。12日下午，堰塞体上挖出了一条深8米、底宽5米的泄流槽，这使堰塞湖库容明显减少，有效降低了溃坝风险和上下游的淹没风险。
刘宁称，目前，堰塞体总体安全可控。接下来，将在“应急处置”阶段形成的泄流槽基础上，进一步扩槽深挖，降低溃堰风险；并进一步提高堰塞体右岸应急泄流通道的泄流能力，使堰塞湖水量水位得到有效降低；此外，还将健全水文气象预警预报机制，实时监控堰塞湖及其周边地区，严防可能发生的滑坡、泥石流、崩塌等次生灾害。
刘宁还透露，经初步研究，后期将变堰塞湖为控制性水库，使其成为具有综合效益的水利工程，发挥灌溉、发电、防洪、旅游等功能。
