Dori is located between two very large barrages. One barrage is very old and the other is under construction. It should be finished in 2005. There are also many slightly smaller barrages that form all over town during the rainy seasons. These smaller barrages make Dori a difficult place to navigate in the rainy season. Sand is another obstacle encountered in navigating Dori. During the dry season it is difficult to ride your bike through the sand.
