Canyon Lake, Texas: Boating Guide
Canyon Lake TX boating guide: 18 public ramps, 125 ft max depth, the 909-ft pool, level on Oct. 17, 2026, marinas near the lake and Texas zebra mussel rules.
Canyon Lake in Comal County, Texas, is a clear Hill Country reservoir on the Guadalupe River with 18 public ramps and launches in the Texas Parks and Wildlife Department (TPWD) inventory, owned and operated by the U.S. Army Corps of Engineers. On October 17, 2026 it stood at 907.7 feet, 97.2% full, about 1.3 feet under its 909-foot conservation pool (Marinalo data, October 2026, measurement date Oct. 17, 2026), and TPWD lists its maximum depth at 125 feet.
This guide covers what kind of lake it is, the ramps, marinas listed in Canyon Lake, the level and what low or high water changes, and the rules, including the zebra mussel drain law that TPWD flags on this lake.
Canyon Lake at a glance
| Item | What the sources say |
|---|---|
| Location | On the Guadalupe River, 16 miles northwest of New Braunfels, in Comal County (TPWD) |
| Owner and operator | U.S. Army Corps of Engineers (TWDB, TPWD) |
| Built | Construction began in 1958 and finished in 1964 (TWDB); TPWD lists impoundment in 1964 |
| Purposes | Flood control, hydropower, water supply and recreation (TWDB) |
| Surface area | 8,308 acres at conservation pool; about 12,890 acres at the top of the flood pool (TWDB) |

Canyon Lake is a flood-control reservoir, so the level can move. TWDB gives a flood pool that reaches 943 feet, 34 feet above conservation pool, and a lake that deep into flood storage is not a normal boating day.
Public boat ramps
Marinalo lists 18 public ramps and launches from the TPWD inventory. They include Canyon Park, Comal Park (two ramps), Cranes Mill Park, Joint Base San Antonio Recreation Park, North Cranes Mill-Mystic Shores, North Park and Potter's Creek Park (two ramps), plus six ramps named only "Canyon Lake Boat Ramp". Use the Canyon Lake boat ramps page to tell the identically named ones apart. The inventory has no trailer-space counts, so we give none.
One practical point from the Corps: the Canyon Lake Office no longer accepts cash payments for any USACE-operated campground or boat ramp, so bring a card. The Corps office is at 601 C.O.E. Road in Canyon Lake and answers at (830) 964-3341 on weekdays. Joint Base San Antonio Recreation Park is a military recreation area, so ask about access rules before you head there. For other lakes and the coast, browse all Texas boat ramps.
Current level and what low water means
At 907.7 feet, Canyon Lake is 97.2% full and within about a foot and a half of conservation pool, which is a healthy October reading. We found no published minimum usable elevation for the individual ramps on the Corps pages we could open, so we give none. If the lake falls, the first symptom is a ramp that ends above the waterline or a gravel stretch you cannot trailer over.
- Check the current elevation on the Corps' Canyon Lake page, which links a USGS elevation graph, before you leave home.
- Check the Corps' park and facility closure notices; closures can follow high water as well as low water.
- Low water exposes rock ledges, trees and other hazards along the shoreline, so slow down in coves.
- After a flood, expect closed ramps and floating debris even after the lake starts to drop.
Marinas and fuel
Marinalo has no marina page for the lake itself. Its page for the city of Canyon Lake lists four entries, which we show as marinas listed in a lakeside city rather than as facilities confirmed on the water:
- Marinas in Canyon Lake: Canyon Lake Marina, Cranes Mill Marina, Freedom Boat RV Storage and West Wind American Boat. All four show "rates on request", with no official slip rate on file and no fuel dock.
Because no fuel dock is on file, fill up before you launch or call a marina to ask. The Texas fuel docks map shows what is on file, and our Texas boat slip prices guide explains why many Texas marinas keep rates private. For options off the water, see boat storage options.
Planning a day on Canyon Lake
Pick a ramp on the map first, then confirm with the Corps or the park operator that it is open and how to pay (card only at Corps ramps). Check the lake elevation, the forecast and any park closures the same morning. Fuel is the next question: Marinalo has no fuel dock on file in the city of Canyon Lake, so fill the tank before you launch or call a marina to ask. Keep the first trip simple, learn where the shoreline drops off, and bring a throwable flotation device and a way to call for help. The Corps says to wear your life jacket, and on a deep lake that advice matters because the water gets deep close to the bank.
What kind of boat works here
Canyon is a deep lake with clear to slightly stained water, and TPWD lists it with no aquatic vegetation. That suits wake sports and pontoons alike. If you are choosing a boat for it, compare deck boats and pontoons, and make sure your tow vehicle can handle the boat; see boat towing capacity.
Rules on Canyon Lake
The Corps sets park and ramp rules; read them on its Canyon Lake page. TPWD rules that apply on every public lake:
- Zebra mussels: TPWD's Canyon Lake page carries a boater advisory: "Zebra mussels have invaded this reservoir!" It tells you to clean, drain and dry your boat, trailer, livewells and gear before traveling to another water body, and says draining water is required by law and that possessing or transporting zebra mussels is illegal.
- Drain law: boaters must drain all water from the boat and gear before approaching or leaving a public fresh water body. Violations are generally a Class C misdemeanor, rising to Class B or Class A for repeat offenses. If your boat has been stored in the water on a lake with zebra mussels, TPWD says it must be decontaminated before it moves; call (512) 389-4848.
- Boater education: required for anyone born on or after September 1, 1993 to run a motor over 15 horsepower or a windblown vessel over 14 feet, with a photo ID.
- Wake and night skiing: hazardous wakes are unlawful, no-wake areas mean headway speed, and skiing is not allowed from half an hour after sunset to half an hour before sunrise. See no-wake zones.
- Alcohol: operating while intoxicated (0.08 or loss of faculties) is an offense on the water.
Safety
The Corps' message on its lake pages is simple: wear your life jacket. Our guide to Coast Guard approved life jackets explains fit. For tubes, read boat tubing safety. Check the forecast before you launch, and check the Corps' notices after heavy rain.
