Mackenzie Res NR Silverton is a man-made reservoir located in Briscoe County, Texas. The reservoir was constructed in 1977 by the Canadian River Municipal Water Authority to provide water to the surrounding municipalities. The reservoir has a surface area of 5,675 acres and can hold up to 137,000 acre-feet of water.

The hydrology of the reservoir is primarily supplied by the Silverton Creek and Palo Duro Creek. The reservoir also receives water from the snowpack melt, which contributes to the surface flow. The main use of the reservoir is for municipal and industrial purposes, but it also provides water for agricultural activities such as irrigation.

Recreational activities are limited due to the reservoir's primary use for water supply. However, fishing is allowed in the reservoir, and it is stocked with various species of fish, including catfish and bass. The Mackenzie Reservoir also provides an opportunity for wildlife habitat and birdwatching.
