“This is a dead-end concrete road that runs north from Clay Road.”
— Bryan Dotson
This concrete trail is the top of the Addicks Dam spillway. Though the most common spillway type is located at the lower outflow of a dam, this spillway is at the end of this rolled-earth dam, to be used if the reservoir fills completely. This (and a similar one on the west end) is the "relief valve" to prevent erosional damage to the dam. The reservoir has never been full enough to reach the top of the spillway.
The entrance to the trail is at the top of the dam at Clay Road. Parking is not allowed at the entrance, and the closed gates prohibit motor vehicle entrance.
The trail currently dead-ends about 1000' from Tanner. Please do not trespass on the private property to reach Tanner Road. There is a project underway by Harris County Parks to connect the north end to Tanner Road. As of November 2016, the project is in the land acquisition and permit stage. There are a number of "deer paths" that link to this trail from the east.
Wildlife frequently encountered include deer, coyote, and hawks.
