Better Explanation of Animas Impact Potential

11 am

As I mentioned there is a chance for some rain over the next couple of days. We can talk all about “cfs” and “bank full” and flood potential but I did some digging and found out what it all means, the what that affects whom. The actual gage is just near the Powerhouse. This graph has flood stage on the left and cfs on the right. An explanation is below the graph that gives you very good examples of who would be affected and at what stage.

Example “6 Lowland flooding is likely in the vicinity of Timble and Hermosa.”
