Early Tuesday, a major dam outside Houston began to overflow, threatening some of the hardest-hit neighborhoods to the west of the city. Engineers had tried to prevent Addicks Reservoir from overspilling by releasing some of its water Monday, but flood control officials reported Tuesday morning that water was beginning to seep over the top of a spillway, the first time water had breached the dam.
