The following is a video that shows two streams going into the San Marcos River, one from the East and one from the West. The one from the west brings in a lot of silt, the one from the East, none that can be seen. From the East the water flows across a grass filled ditch, the one from the West flows from the direction of Downtown. I suspect that much of the silt on the West came from the parking lot construction project off of CM Allen, where I assume the City took all “required” precautions in order to minimize the flow of silt into the river. However, this silt may have built up here over the years…not sure. If this much silt is in the river from the relatively minimal rain we have gotten over the last couple of days, I wonder what would have happened during a real gully washer?
