Soil survey area

Beaver County, Oklahoma

Survey Area OK007• Oklahoma
The short version

The most common soil here is Alopark, on about 14% of the land: a sandy loam, gritty and crumbly. Mocane and Dreyfoos come next.

About 92% of the land drains well, and 8% stays wet for long stretches.

USDA rates 36% of the land very limited for a standard septic drain field, and 22% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 11% of the land floods occasionally or more, and bedrock lies within 40 inches under 9% of it.

Soils change over short distances, so look up an address below for the soil at that exact spot and the reasons behind each rating.

Soil Orders in This Area

The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.

Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.
Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.
Mollisols
Fertile grassland soils with thick, dark topsoil. Among the best for agriculture, building, and gardening.
Inceptisols
Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.

What This Means

Building & Foundations

About 22% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 36% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.

Gardening & Agriculture

Well-drained soils on sloped terrain — good for most plants but watch for erosion. Terracing, contour planting, and mulching help retain moisture and topsoil. Drip irrigation is more effective than sprinklers on slopes.
