Acequia as Deed Boundary in a Northern New Mexico Land Grant
You are surveying a 6.2-acre parcel in Rio Arriba County within a Spanish community land grant confirmed by Congress in 1909. The 1996 deed begins at “the center of the Acequia Madre del Rio,” runs N 12° E 480.0 ft, then east to “the west line of County Road 76,” then along the road. The client’s wire fence stands 9 ft west of the acequia centerline. The neighbor irrigates from the ditch, cleans it each spring, and has done so since 1978. A 1940 survey in the chain shows the lot lines ending at the ditch bank, not the center. County Road 76 was widened in 1972; the deed has no new description, and the county has no recorded right-of-way deed. The client wants the fence declared the boundary and asks whether the ditch and road are “just easements” that can be ignored on the plat.
1. How should the deed call to the center of the acequia be interpreted against the fence and the 1940 survey?
Read the worked answer
The deed call to the center of the Acequia Madre is a call to a monument. If the ditch is the same acequia, the centerline controls the boundary, not the bank and not the wire fence. The 1940 survey may show how an earlier surveyor interpreted the lot, but a later unambiguous deed call ordinarily prevails over an unrecorded survey that contradicts it; I would still examine the 1940 map and the grant documents for a different intent and for any recorded correction. The fence 9 ft west of center is possession, not title. The acequia itself may be owned to the center subject to an easement for irrigation and maintenance, so the plat can show both the centerline boundary and the easement. I would not ignore the ditch as “just an easement” if the deed uses its center as the boundary.
2. How do you establish the west line of County Road 76 after the 1972 widening?
Read the worked answer
The west line of County Road 76 must be established from the road records, not from the edge of pavement. I would pull the county road petition, dedication, right-of-way map, and any 1972 widening files, and compare them with the deed calls and the 1940 survey. If the county acquired additional right-of-way by deed or prescription, the public easement may be wider than the original road, but the fee boundary in the parcel deed does not automatically move to the new pavement edge unless the deed or law says so. The deed’s “west line” should be tied to the recorded centerline and width. I would show the road right-of-way, the parcel line, and any apparent encroachment, with a note on the source of the road line.
3. What should the plat show regarding the acequia, the fence, and the road?
Read the worked answer
Show the acequia centerline and both banks, label the irrigation and maintenance easement, show the fence as a possession line with its 9-ft offset, and depict the county road right-of-way with its source document. Add notes that the boundary follows the deed centerline call, that the fence is not the boundary, and that the road line is based on county records. If the records conflict, show the conflict and do not force a closure that hides it. The client should be told that a quiet-title or boundary-line agreement may be needed if they want the fence recognized.
