The Gowen series consists of very deep, well drained, moderately permeable soils that formed in loamy alluvium. These soils are on nearly level flood plains. Slopes are dominantly less than 1 percent, but range up to 2 percent. Solum thickness is greater than 80 inches. Surface horizons having moist color values of less than 3.5 and evident structure, range in thickness from 24 to about 60 inches.
Reaction ranges from neutral to moderately alkaline.
The soil is noncalcareous above 50 inches. The A horizons have hue of 7.5YR or 10YR, value of 3 to 5, and chroma of 1 to 3. Texture of the A1 horizon is loam, sandy clay loam, or clay loam, with minor areas of fine sandy loam. The A2, horizon is loam, clay loam, or sandy clay loam with in the Bk or Bw horizons. The Bw or Bk horizons have hue of 10YR or 2.5Y, value of 3 to 7, and chroma of 2 to 6.
