General Description

The terrain of Horsefly Mountain Ranch has aesthetically desirable character, with a classic hill country charm over dense brush-covered hills, productive pastures in the low-lying areas, and limestone plateaus. Entering the ranch, you wind through live oak motts and cedar breaks, crossing over a trickling limestone bottom creek before emerging through a small valley of pecan trees into a native pasture where the home, improvements, and private lake remain hidden behind the hills from the outside world. The vegetation includes trees such as oak, walnut, pecan, elm, willow, mesquite, and cedar. A fifteen-acre lake sits adjacent to the barns and pens, a short distance from the house, and serves as a highly desirable primary water feature, complete with a steel gazebo/fishing pier. Six additional ponds are located throughout the property in addition to the large lake. A gravity-fed natural spring water system distributes water to the infrastructure and livestock from a system of underground pipes that percolate water to an 80,000-gallon holding tank and a series of livestock troughs around the ranch. The primary residence, built of steel and concrete, is positioned for panoramic views of several pastures between the hills with total seclusion from neighboring properties or the roadways. The southern portion of the ranch has more frequent and drastic elevation changes, providing the elevation necessary for wind production, and prime areas for hunting and recreational aspects, while the northern areas include more sheltered and productive pastures and valleys utilized for grazing and hay production. Improvements are tasteful, functional, and logically placed in relation to the terrain and supporting infrastructure. Complete privacy, function, and seclusion were goals achieved with the thoughtful design and placement of the improvements without sacrificing aesthetics.
