On the third day, we drove about an hour west to the San Juan River. There was a concern that the river would be too fast to fish. Just by looking at this picture, you can tell the river is flooding. I haven't seen it at a normal state, but supposedly this stage was 5-10 feet above the average height. Rivers are measured in CFS (cubic feet per second). The normal river speed is 500 CFS when we fished it was at 5000 CFS. This is the highest the river is to be fished at.
