Along the South Platte in Adams County, irrigation water is its own question
Many older parcels in farming Adams County carry canal or ditch irrigation water that is separate from the household water that comes out of the tap.

Adams County grew up as farm country along the South Platte River. A web of ditches and canals still carries river water out to fields, yards, and pastures across the county. Barr Lake, near Brighton, is itself filled by one of these ditches drawn from the South Platte.
That history matters to a buyer because a property here can have two completely different kinds of water, and mixing them up causes trouble.
One is the household water that comes out of the tap, from a city, a district, or a well. The other is irrigation water, delivered through a ditch or canal to green up the land. Irrigation water often comes as shares tied to the parcel, with its own schedule and its own rules. It is not drinking water, and having it does not mean the home has plenty of domestic supply.
Why it matters: a listing that mentions “irrigation” or “ditch rights” may be describing water for the yard or a few acres, not the household supply. Each has to be checked on its own — what serves the house, and what irrigation actually transfers with the sale.
Verify the household water and the irrigation water separately, using the state water agency and the local ditch company or provider.
