What this means today

At 107 cfs the San Marcos River is inside the runnable range but only 7 cfs above the 100 cfs floor, so it is sitting at the shallow end of what this reach runs at. A dry few days would take it under.

Over the last 24 hours it has barely moved, 107 cfs to 107 cfs. Daily means over the past 7 days have run between 107 cfs and 113 cfs, ending roughly where it started.

Paddling Staples to Martindale

San Marcos River at Staples to Martindale is a 6-mile Class II run in Texas — bouncy wave trains and the occasional small rapid. Most paddlers put in at Staples dam area and take out at Martindale (Old Bridge), a trip that runs about 3.5 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 100–900 cfs (a conservative estimate — see our methodology). Much below that and the San Marcos 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 08171400 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.

Flows here are usually most dependable March–October. Spring can run high after rain or snowmelt, and late summer often drops too low to float well — but the gauge always beats the calendar, so check today's reading before you go.
