Watershed Delineation Tools
The following slides provide a comparison of web-based watershed delineation tools.
Floodplain and Soil Data
Floodplain Information: The area of the Upper Truckee River Watershed that I am analyzing is the area between the Upper Truckee River and Trout Creek. This area is known as the Truckee River Marsh area. One would think that an area situated between two bodies of water would be subject to flooding. However, as shown in the image below, this area is designated as FEMA flood zone X, which represents an area of minimal flood hazard (FEMA, 2021). Zone X has a 0.2 percent annual chance of flood (FEMA, 2020). Soil Data: This area of the Upper Truckee River Watershed is characterized primarily by Tahoe complex and Christopher-Gefo complex soils (USDA, 2019). Other soils include Watah peat and Marla loamy coarse sand. Tahoe complex soil occurs at 0 to 2 percent slopes, is found at elevations of 6,220-7,970 feet, has very poor drainage, and is not classified as prime farmland. Christopher-Gefo complex soil occurs at 0 to 5 percent slopes, is found at elevations of 6,220-6,410 feet, has good
I like how easy and useful this delineation tool PowerPoint was to learn from. Informative and not super busy. I also enjoy your blogs background, is that a photo of your watershed?
