罗贡坝是一个位于塔吉克斯坦斯坦国家直辖区境内的亚粘土斜心墙土石坝，设计坝高335米。为目前世界上设计最高的大坝。罗贡坝是瓦赫什河最上游一个梯级大坝。距下游的努列克坝70km。

坝址的岩层由砂岩、粉砂岩和泥板岩组成。地震烈度为9度。峡谷呈S形。枯水期河面宽50～80m, 在坝址处河宽缩窄至20m。多年平均流量640m/s。1000年一遇设计洪峰流量为5750立方米/秒。坝址气温夏季最高达40°C,冬季可达-31°C。

坝址上游500m处，地下水位以下20m深，发现盐岩层，厚20m。为了防止盐岩层的化学管涌及由此而引起的心墙基础的可能变形，大坝上游棱体大部分布置在盐岩层之外。盐岩的下游面进行专门防护，并在基岩上作水泥灌浆和化学固结灌浆。

Rogun Dam is an embankment dam in the preliminary stages of construction on the Vakhsh River in southern Tajikistan. It is one of the planned hydroelectric power plants of Vakhsh Cascade. Over three decades only preliminary construction has been carried out on the dam. Due to its controversial state, construction was suspended in August 2012 pending World Bank reports. The dam has drawn complaints from neighbor Uzbekistan, which fears it will negatively impact its lucrative cotton crops. The dispute over the project has contributed significantly to bitter relations between the two former Soviet republics.
