GRDA owns the flowage easement rights for Grand Lake and Lake Hudson. Prior to initiation of activity to occur on lake property owned by a party other than GRDA, the landowner should consult their abstract of title, or the county land records to determine if their property is subject to a flowage easement. If the property is subject to a flowage easement, the landowner shall consult with GRDA regarding what activities may or may not occur on the land subject to the flowage easement.
