What this means today

At 101 cfs the San Marcos River is inside the runnable range but only 21 cfs above the 80 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, 103 cfs to 101 cfs. Daily means over the past 7 days have run between 99 cfs and 102 cfs, ending roughly where it started.

Paddling Luling Zedler Mill

San Marcos River at Luling Zedler Mill is a 6-mile Class I run in Texas — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Zedler Mill Park, Luling and take out at Zedler Mill Paddling Trail take-out, 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 80–1,200 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 08172000 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.
