Walk the back fence line of almost any acreage property in Loomis and you'll cross a narrow concrete or dirt-lined channel that doesn't look like it belongs to anyone. No sign, no gate, just a trickle or a dry groove cutting across the pasture. It reads like landscaping. It isn't. That channel is infrastructure, and somewhere on file with the Placer County Water Agency is a specific account tied to that parcel that determines whether water actually shows up in it.
Listing descriptions for Loomis ranchettes and hobby-farm parcels routinely quote a water right the way they'd quote square footage: a fixed number, stated with confidence, meant to reassure. "PCWA canal water, 2 miner's inches in summer, 1 in winter" reads like an amenity. What it actually describes is a seasonal service entitlement, delivered through infrastructure PCWA doesn't fully control, governed by rules most buyers never see until after they've already waived their contingencies. The number in the listing is real.
The unit itself is a fossil, and PCWA still bills by it
A miner's inch is a water-measurement unit that dates to the Gold Rush, and PCWA's own rate schedule still uses it today. One miner's inch works out to roughly 11 gallons per minute. It's an odd thing to find on a modern utility bill, but PCWA measures untreated irrigation water this way because the canal system it runs was built to move water to mining claims and orchards, not household taps, and the accounting never fully modernized. When a Loomis listing says "2 miner's inches," it's citing a number straight off a PCWA account, not a marketing estimate.
That specificity is exactly why buyers should stop treating it as decorative. A number that precise came from somewhere, and it's tied to a customer account, a physical delivery point, and a set of agency rules, not to the deed itself.
Why the number changes twice a year, and what that means for your closing date
PCWA's current rules set the winter irrigation billing period from October 16 through April 15. The rest of the year is summer delivery. That split isn't arbitrary. A meaningful share of PCWA's canal water actually moves through infrastructure owned by PG&E, and PG&E shuts down sections of that system every fall for routine maintenance, usually starting the weekend just before October 15. Ahead of that outage, PCWA has to physically change out the delivery orifice at every customer's turnout, swapping from the summer setting to the smaller winter one.
That's the origin of the two numbers in the listing. "2 miner's inches in summer, 1 in winter" isn't a range or an estimate. It's the literal before-and-after of a mechanical orifice swap that happens on a calendar PCWA controls, tied to a maintenance schedule PG&E controls. If you close escrow in November and expect to see the summer number in your pasture, you'll be disappointed for reasons that have nothing to do with drought, your well, or anything wrong with the property. The system flips every October whether anyone bought or sold a house that month or not.
| Period | PCWA billing window | What shows up at the turnout |
|---|---|---|
| Summer irrigation | Roughly April 16 through October 15 | The higher figure quoted in most listings |
| Winter irrigation | October 16 through April 15 | The reduced figure, after PCWA resets the orifice ahead of PG&E's fall canal maintenance |
The entitlement can be split, but only through PCWA, not through the county
If you're the kind of buyer this affects most, an acreage or land investor weighing a future parcel split, there's a second rule worth knowing before you write the offer. PCWA's own administrative rules address exactly this scenario: when a parcel with an existing irrigation delivery is split, the existing water delivery can be divided among the newly created parcels, but only through PCWA's process, not automatically through a county-recorded final map. A tentative subdivision map and a survey establish your new lot lines. They don't, on their own, tell PCWA how to divide a single canal turnout among however many parcels now exist behind it.
The same rules also address what happens when two parcels already share a single turnout, a common setup on older Loomis acreage that was split generations ago. PCWA guarantees each party on a shared connection a minimum of half a miner's inch, but that minimum is a floor, not necessarily what you're getting today. If the listing you're looking at shares a turnout with a neighboring parcel, the number quoted to you may already reflect that split, or it may not, and the only way to know is to ask PCWA directly rather than trust the listing sheet.
The ditch is yours to maintain, whether or not you asked for it
Separate from the water right itself is the physical channel carrying it, and the Town of Loomis is direct about who's responsible for that. According to the town's own published guidance, if a drainage ditch or canal runs through your property, maintaining it is the property owner's job. Not the town's. Not automatically PCWA's, unless the specific channel is one of PCWA's own delivery facilities, in which case PCWA's rules require you to provide the agency safe access to its equipment on your land whenever needed.
In practice that means a buyer touring a Loomis ranchette with an open ditch crossing the back acreage is looking at a future maintenance line item, not a scenic feature. Clearing debris, keeping the channel functional, and giving PCWA access when they need to service a turnout or clean a screen are the new owner's responsibilities starting the day escrow closes.
Water rights and dirt are two different files
None of this is unique to eccentric water agency policy. California law generally treats an easement, including the kind that lets a canal cross a parcel, as something that survives a change in ownership, as MBK Chapman explains. The reverse is also true: an easement can be legally abandoned under the state's own abandonment statute. The point for a Loomis buyer is the underlying structure: the physical right-of-way, the water delivery account, and the parcel of dirt are three separate legal objects that happen to sit on top of each other.
What to actually verify before you remove contingencies
A handful of concrete steps close the gap between what the listing states and what you'll actually own:
- Call PCWA's Customer Services directly and ask them to confirm the current account status, delivery size, and any shared-turnout arrangements tied to the specific parcel, rather than relying on the seller's description
- Ask whether the account is in good standing
- If the parcel shares a canal turnout with a neighbor, get that arrangement in writing and confirm your guaranteed minimum
- If you're buying with a future parcel split in mind, contact PCWA's real property program before finalizing your subdivision plans, since the water entitlement doesn't split itself
- Ask who has historically maintained any ditch or open channel crossing the property, and budget for that responsibility starting at close
FAQ
Who do I contact to verify a water right before closing? PCWA's Customer Services department can confirm account status and delivery details for a specific parcel. Their real property program handles right-of-way and easement questions tied to a project or a planned parcel split.
What happens to the water right if I split the parcel later? PCWA's own rules allow an existing irrigation delivery to be divided among newly created parcels, but that division happens through PCWA's process. A county-approved final map and survey establish your new lot lines. They don't instruct PCWA on how to divide the water.
