Rain

Rain makes the river go. There has been a drought this spring, and overall the rivers are low in the hill country. However, rain has fallen on much of the course the last 48 hours. The above data from the USGS data centers reflects that. This is a very good thing, as much of our training runs were marked with shallow water and dragging the canoe.

The San Marcos River arises from the Edwards Aquifer, so it’s not as dynamic as other rivers with large catchment basins. The Guadalupe, which the San Marcos eventually joins, behaves more like a normal river with rain fall. Lucky for us, the water goes down stream and will raise levels for the whole race.
