Tule Creek Lake, also known as Mackenzie Reservoir, is an 896-acre impoundment located 10 miles northwest of Silverton, Texas on Tule Creek, a tributary of the Prairie Dog Fork of the Red River. Created in 1974, the reservoir features steep rocky sides within a canyon off the Caprock, with water depths reaching 150 feet and averaging 52 feet at conservation pool level.

The lake has very little aquatic vegetation, with most structure consisting of flooded timber and terrestrial vegetation. The water is typically clear with 4-6 foot visibility. The steep canyon sides provide significant wind protection, making this a good paddling destination even on breezy days.

The lake experiences severe annual water level fluctuations of 4-10 feet, which can affect access conditions. The reservoir's elevation is 3,100 feet above sea level at conservation pool. Most of the cover consists of rock and boulder formations with some areas of flooded timber in the coves. Several islands dot the open water.

Due to its remote location and challenging access points, the reservoir typically sees very low visitor traffic, offering a quiet paddling experience away from crowds. Before planning a trip, paddlers should contact the Mackenzie Municipal Water Authority regarding current water levels and access conditions.

The steep rocky sides and deep canyon setting create a distinctive paddling environment, though they can make shoreline access challenging in many areas. When exploring the lake's 165 miles of shoreline, paddlers will find the best protected water in the numerous coves featuring flooded timber.

The lake supports populations of largemouth bass, crappie, and hybrid striped bass, making it possible to combine paddling with fishing. Wildlife viewing opportunities exist along the rocky shorelines and wooded coves.
