How Long is Your Favorite Lake

One of the most important things to consider when looking for the perfect lake house is knowing the differences between the various lakes. The map at the bottom of the page provides the length and maximum width of each of the highland lakes. Each of these lakes provide the necessary width, depth, and length for general boating, Waterskiing, Wakeboarding, and Wakesurfing. The most common lengths of the boats on these lakes range from 22’-25’, and drafts (depth of boat) from 27”-32”.

Lake Travis is approximately 57.6 miles long in terms of usable/boatable lake. 10.1 miles of that is on the Pedernales River. At it’s widest point, it is 2.16 miles wide, which spans from the dam at the end of the lake to Comanche Canyon Ranch. Although Lake Travis is not a constant level lake, it has many places that historically are always boatable. According to Texas Parks and Wildlife, the official surface area of Lake Travis is 18,622 acres and has a maximum depth of 190 feet.

Lake Austin is 20.3 miles long in terms of usable/boatable area, with the widest distance of 1,502.62 feet. It spans from the Mansfield Dam at the end of Lake Travis all the way down to the Tom Miller Dam. It has the surface area of 1,599 acres and a maximum depth of 75 feet according to Texas Parks and Wildlife.

Lake LBJ is 24.29 miles long in terms of usable/boatable use, with the widest distances of 2.78 Miles (North to South) and 1.80 Miles (East to West). The Llano arm of Lake LBJ is 4.29 miles long of usable/boatable depths. It is constant level and has a maximum depth of 90ft and a surface area of 6,449 acres according to Texas Parks & Wildlife.

Lake Marble Falls is the section of the Colorado river spanning from the Lake LBJ Dam to Starke Dam. Lake Marble Falls is 5.32 Miles long (in terms of normal boatable use), and has a maximum width of 1,116 feet. TPWD has it’s maximum depth listed as 60 feet and a surface area of 611 acres.

Lake Buchanan is 26.40 miles long, with the widest points measuring at 7.9 miles (North to South) and 6.71 miles (East to West). According to Texas Parks and Wildlife Lake Buchanan has a maximum depth of 132 feet and a surface area of 22,211 Acres. Because of how deep this lake is, despite the variability of the water level, it would always have areas that are boatable.

Inks Lake is the stretch of the Colorado river between Lake Buchanan and Lake LBJ. Inks Lake is 4.13 miles long and with the widest point near the end of the river which is .678 miles wide. TPWD states that this lake has a maximum depth of 60 feet and a surface area of 831 acres.
