The Snow Water Equivalent (SWE) is not as optimistic as some would hope. Below is a screen shot taken from the NRCS interactive website. The color-coded points are the locations the SWE is measured. The percent value is compared with the peak based on the median peak which is calculated for the period of record.

The period of record minimum (when they started recording data) is shown below which varies from 1977 to 2005.

The period of record for the maximum is shown below. If the color of the dot changes than they are no longer collecting the peak data. It looks like a lot of sites are no longer being collected.

Here is where I will be posting my thoughts on Colorado Water, watershed health, river assessments, flood risks, etc.

A primer on Fluvial Hazard Zone Mapping with LiDAR data

The is a very technical post. This is a primer to discuss how LiDAR data is collected, filtered and manipulated to create digital elevation models (DEM) and how those DEMs might be used to identify fluvial geomorphic signatures that indicate where a flood hazard might exist. LiDAR data is commonly used in geomorphic analysis, hydraulic…
