Aquifer 1224: Chetwynd Artesian
Aquifer 1224 (Chetwynd Artesian) is a confined sand and gravel (glacial) aquifer of 11 km² in the Peace River Regional District, mapped in 2017. The province rates its productivity moderate and its vulnerability to contamination from the surface low; its demand is not rated. 13 wells on record are linked to it; water-supply wells there are typically 89 m deep and tested at a median 75.7 L/min. It lies under Chetwynd (52%), Peace River, Electoral Area E (48%).
How the province rates it
Productivity moderate, vulnerability low, demand not rated.
| Rating | What it means | |
|---|---|---|
| Productivity how much water the aquifer gives up to wells, judged from well yields, the aquifer material and pumping tests | moderate | Middling yields: the guide's moderate band is medium sand, or typical well yields of about 0.3 to 3 L/s (18 to 180 L/min). |
| Vulnerability how easily something spilled at the ground surface could reach the water, judged from what lies above the aquifer and how deep the water is | low (class C) | Better protected (class C), usually by clay or silt above it or deep water. Not immune: a gap in the cover or a badly sealed well can still let contaminants in. |
| Demand how much the aquifer is used now, judged from the number and density of wells and what they're used for | not rated | The province hasn't rated this for this aquifer. |
| Level of development Inferred demand compared with productivity | unclear | Unclear: the province hasn't rated both demand and productivity. |
Ratings are the province's, set when the aquifer was mapped (2017) from wells, geology and local studies. Vulnerability is about the ground, not what's built on it: a well-protected aquifer under a busy area can still be at more risk than an exposed one in the bush.

The wells in it
13 wells on record are linked to this aquifer.
| Wells linked | 13 (11 water-supply) |
|---|---|
| Water-supply well depth | median 89 m; middle half 69.3 m to 149 m (11 wells) |
| Tested yield | median 75.7 L/min; middle half 75.7 L/min to 379 L/min (9 wells tested) |
| Water level below ground | median 5.2 m when drilled (2 wells) |
| Flowing (artesian) wells | 11: water rose to or above the ground when drilled |
| Drilled | 1995 to 2012 |

Depths are how deep the driller finished the well; yields are the driller's test, often an hour or less, in litres per minute. A domestic well's yield is usually judged against the household's peak use; ask a driller what's enough for yours.
Where it is
Outline simplified by us from the provincial map; not for locating a lot.
| Kind | Confined sand and gravel - glacial |
|---|---|
| Location, as described | North of Chetwynd along Centurion Creek |
| Area | 11 km² |
| Water use | Several uses (for example household wells, water systems, irrigation or industry) |
| Water quality concerns | None documented |
| Mapped | 2017 |
Confined: a layer of clay, silt or till lies over it, which slows water (and spills) from the surface; wells reach it through that layer. The province's page for this aquifer lists the studies behind it and its observation wells: GWELLS aquifer 1224.

What this record doesn't cover
The province maps aquifers where wells and studies give enough to go on, mostly in settled valleys; most of BC isn't mapped, and a lot outside every outline can still have groundwater. Outlines are drawn from geology and well logs at the scale of the study, so an edge can be well off on the ground, and one aquifer can lie under another. Wells are linked to an aquifer by provincial staff from the driller's log: not every well inside an outline is linked, and well depths and yields are as the driller reported them, often from a short test.
These are mapped ratings and drillers' records, not a test of any one lot. Before you buy a property on a well, or plan to drill, ask a qualified hydrogeologist or a registered well driller what this aquifer gives where you are, and test the water.
