Nevada Soil Drainage Rankings

Nevada

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%. 45% of the land in Fallon-Fernley Area, Nevada, Parts of Churchill, Lyon, Storey and Washoe Counties is poorly drained, so building, septic and gardening there often call for drainage work, engineered septic designs or raised beds.
