Provincial Auditor Judy Ferguson says the Water Security Agency has significant work to do to bring unapproved drainage works into compliance. In Volume 1 of her 2018 Report, Ferguson says existing unapproved drainage works, particularly those located in areas of higher risk of flooding, can cause damage and lead to loss of wetlands. Drainage works are any human-made activity intended to remove or reduce water on land or just below the land surface. Saskatchewan has between 1.6 and 2.4 million acres of land with unapproved drainage works. Ferguson says the agency also needs to report more information, such as the number of proposed drainage approval applications received and approved, and the average time it takes to bring drainage works into compliance.
