In some parts of British Columbia, high levels of precipitation and seasonal runoff can cause saturation of agricultural soils. Most agricultural crops are adversely affected by ponded water on the soil surface and/or prolonged soil saturation in the root zone.
The Drainage Management Guide is is one of the supplementary documents to the Environmental Farm Planning program prepared to assist British Columbia farmers and ranchers to improve their farm operations and implement beneficial management practices.
This manual is intended as a general reference although specific drainage design criteria are included. It describes generally accepted drainage practices and principles, yet is not meant to be the sole source of information on soil and water management
