Lac-au-Saumon Water Well Depth & Hydrogeology
Regional groundwater summary • GWDrill Historical Log Extraction
Bottom Line Up Front
In Lac-au-Saumon the median well is 129 feet deep and draws from Crystalline Bedrock (Granite/Gneiss) bedrock, which supplies 85.7% of wells here. Water is very hard at about 325 mg/L, so a softener is standard equipment. Rotary drilling is routine and 94% of wells serve ordinary household use. Treatment emphasis: low ph, slightly corrosive. Crystalline fractures favor low-alkalinity corrosion.

Where This Report Applies
Approximate boundary of Lac-au-Saumon
Shaded area is an approximate municipal outline for orientation only. Well records are aggregated across the entire Lac-au-Saumon.
Depth Distribution
Most completed wells fall near the median depth of 129 ft.
Median depth of 129 ft falls inside the reported range. Deeper completions here usually mean higher mineral content but steadier year-round pressure.
Aquifer Composition
Bedrock and drift aquifers recorded by drillers in this area.
54 wells Eastern Manitoba crystalline rock. Yields soft, slightly acidic water with minimal dissolved solids.
6 wells Shallow to intermediate glacial drift aquifer deposited in alluvial channels or outwash plains. Yields softer water but requires continuous sediment filtration and shallow bacterial monitoring.
3 wells Unclassified hydrogeological formation from legacy provincial drill records.

Present Mineral Risk
- Scale build-up in kettles, heaters and fixtures
- Dissolved iron and manganese staining
- Elevated calcium and magnesium from Crystalline Bedrock (Granite/Gneiss) bedrock
Test before purchasing treatment. Hardness varies well to well within the same quarter section.
Size custom treatment system for this waterDrilling Activity
Historical permit and construction activity by decade.
14% of wells are over 30 years old. Steel casing installed before 1995 can lose integrity, so any older well should get a casing inspection and a bacterial test before you rely on it.
Data-Driven Prescription
The treatment system this water needs
Generated from 325 mg/L hardness, crystalline bedrock (granite/gneiss) and a 129 ft median completion depth, for a four-person household. Adjust the assumptions in the builder.
