Paddling Longhorn Dam to US 183 (Austin)
Colorado River at Longhorn Dam to US 183 (Austin) is a 6-mile Class I run in Texas — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Longhorn Dam / Festival Beach, Austin and take out at Roy Guerrero Park / US 183, a trip that runs about 3 hours at a relaxed pace.
Whether it's worth the drive comes down to flow. This section generally paddles well at 150–4,000 cfs (a conservative estimate — see our methodology). Much below that and the Colorado River gets low and bony, so you end up scraping gravel and walking the shallows; well above the top of the range it turns fast, cold and pushy, which is a more serious day than most casual boaters want. We read USGS gauge 08158000 about every 30 minutes and compare the live number to that window, so the verdict at the top of this page reflects conditions right now rather than a monthly average.
This reach can run year-round in a typical year, though levels still swing with rain and dry spells — the live gauge always beats the calendar, so check today's reading before you load the car.
