Ed:
In my opinion this isn't exactly a matter of personality, it is a highest and best use issue, which HAS to be resolved at the start of the appraisal process. Communication!
Having appraised some wierd rights in my day I would have to add that this is a more than just a sematics issue! You are right, and so are the property owners who say thier property is 'worth' more....
The land is at least in theory, subejct to different 'highest and best use' IF tied to the H20 rights ...be they shares or be they 'rights'... AS LONG AS THEY CONVEY WITH THE PROPERTY, and the land is not altered to 'dry'...
This works fine and good as long as the precedence actually produces useable water to the land <_< ... something that may be more in question as the legalities and the realities of whether ANYTHING flows down a given ditch in a dry year. Ray has the water thing dead on! Precedence was the cause of shooting fury in yesteryear and may hit that level again in years to come

.
Most 'rights' are subject to contractual agreement and or recordation someplace sometime. :idea: The lender CAN encumber the water shares through deed restriction, can they not?
Nancy has it aright!
Follow me closely here: the property with the water SHARES (no mater how titled)
if and ONLY if properly encumbered by a lender would typically have more 'value' than the dry property with no water 'rights' be they shares or rights.
All the lender has to do and YOUR job as a appraiser must then be to convey to the lender that the 'shares'
must be seperately encumbered, by legal means
to stay with the land for the life of the loan and any recommitals for the loan.
The fact is this is more than a 'personal property issue'. It is a functionality issue directly affecting the highest and best use of the land, therefore value. Client communication, H&BU analysis and then and only then: VALUE opinion...
Now getting into the specific value of the right/share which has direct coorelation with the strength of the right in dry years is a whole 'nother ball of barb-wire. Ray knows what I mean when I say you gotta be REAL careful if you are gonna snip at a ball of wire.
Pasting water rights or a length of barbwire in a report or wall display packet is more tricky than it looks. You can get into a world of hurt with water or wire if you don't understand how to cut either one.
