Nevada Soil Drainage Rankings
How well does the soil drain across Nevada? We ranked every USDA survey area by the percentage of land classified as "well drained." Areas at the top of the list have soils where water moves through at a healthy rate — favorable for building, septic, and gardening. Areas at the bottom have more waterlogged or slowly-draining soils that may require engineered solutions.
The best-drained survey area is Desert National Wildlife Refuge Area, Nevada, South Part at 100% well-drained soils. The most drainage-challenged is Fallon-Fernley Area, Nevada, Parts of Churchill, Lyon, Storey and Washoe Counties at 27%. With 45% poorly-drained soils, properties in Fallon-Fernley Area, Nevada, Parts of Churchill, Lyon, Storey and Washoe Counties should budget for drainage engineering, alternative septic designs, or raised-bed gardening.
