Another Soil Question - 07/02/09 04:11 AM
Im totally new to the pond thing , just starting to investigate if its possible to have a small pond on our family farm.
But I do have this soil stuff, and from what Ive read it doesn't seem promising...
Any Input of any kind would be nice.
Spokane County, Washington
BbB—Bernhill silt loam, moderately shallow, 0 to 20 percent slopes
Map Unit Setting
* Mean annual precipitation: 20 inches
* Mean annual air temperature: 46 degrees F
* Frost-free period: 100 to 125 days
Map Unit Composition
* Bernhill and similar soils: 100 percent
Description of Bernhill
Setting
* Landform: Hills
* Landform position (two-dimensional): Backslope, footslope, toeslope
* Landform position (three-dimensional): Side slope, base slope
* Parent material: Glacial till mixed with a component of loess and volcanic ash
Properties and qualities
* Slope: 0 to 20 percent
* Depth to restrictive feature: 20 to 40 inches to lithic bedrock
* Drainage class: Well drained
* Capacity of the most limiting layer to transmit water (Ksat): Moderately high to high (0.57 to 1.98 in/hr)
* Depth to water table: More than 80 inches
* Frequency of flooding: None
* Frequency of ponding: None
* Available water capacity: Low (about 4.8 inches)
Interpretive groups
* Land capability (nonirrigated): 3e
Typical profile
* 0 to 6 inches: Silt loam
* 6 to 16 inches: Gravelly loam
* 16 to 28 inches: Gravelly loam
* 28 to 32 inches: Unweathered bedrock
Personal Notes : The site im looking at is the low point between several unused fields, there's a lot of tress and vegetation in that area that stays greener , also stories from my dad said that there was a small pond there in the spring time when he was a kid...
I guess I would be looking at an excavated pond and the well fill option.
