When it rains in Las Vegas, it can easily flood, hence the city has an elaborate system of flood channels. Water empties into this large basin, located in a residential area near South Point casino, where excess water can be stored befor releasing it downstream. This basin is about half a mile long and a quarter mile wide. The Clark County Regional Flood Control District wants to eliminate the possibility of damage from a 100-year flood. So far, 90 detention basins have been built along with 581 miles of channels and underground storm drains.
