Quick Answer
The five Norfolk County rain gauge setups, ranked by cost: $5 plastic tube on a fence post (cheapest, accurate); $15 graduated cylinder with mount (the homeowner default); $25 funnel-style with overflow vent (best for high-rain areas like Brookline and Newton); $40 wireless display (sends readings to a kitchen unit); DIY straight-sided container (works fine, harder to read precisely). Pick one, place it 3 feet up, away from buildings and trees, read it Monday and Friday.
Why Rain Gauges Are the Cheapest Yard Tool That Saves Real Water
Norfolk County yards default to "water 3 days a week, every week, May through September." That schedule wastes 25–35% of irrigation runtime in a normal summer when MA actually delivers 2–4 inches of rainfall in June and 1.5–3 inches in July.
A rain gauge tells you exactly when to skip a watering cycle. Per USEPA WaterSense, homeowners with rain gauges use 30% less irrigation water than those without. The gauge pays for itself in one summer's water bill.
Five setups that work in Norfolk County yards.
Setup 1: $5 Plastic Tube on a Fence Post
The cheapest accurate setup. A standard plastic tube rain gauge from any hardware store, mounted to a fence post or stake at 3 feet of height. Simple graduations marked in 0.1-inch increments.
Pros: Cheap, accurate within ±0.05", lasts 3–5 seasons. Cons: Has to be checked manually. Squirrels chew them eventually.
Best for: Most Norfolk County yards. Mount on a back-fence post visible from the kitchen window.
Setup 2: $15 Graduated Cylinder with Mount
Step up from the $5 tube — a clear acrylic cylinder with a sturdy mounting bracket. Easier to read precisely, mount stays vertical even when the fence shifts.
Pros: Higher-quality construction, better readability, won't tip in wind. Cons: Same manual-check requirement.
Best for: Norfolk County homeowners running a 6-zone irrigation system who want exact 0.05" precision for runtime adjustments.
Setup 3: $25 Funnel-Style with Overflow Vent
A larger-mouth funnel design — typically 4-inch diameter — that catches more rain and includes an overflow vent so heavy storms (3+ inches in 24 hours, common in Norfolk County thunderstorms) don't blow the tube.
Pros: Handles heavy rain accurately. Less affected by wind underread. Cons: Larger footprint. Needs more open placement.
Best for: Brookline and Newton properties — heavier-clay soils where heavy storms run off and you want accurate measurement of total event rainfall (not just what soaked in).
Setup 4: $40 Wireless Display
A two-piece system: outdoor sensor (collects rain) + indoor base unit (digital display). Reads automatically, logs daily totals, often integrates with a weather app.
Pros: Zero manual checking. Logs history. Most have a freeze-warning feature. Cons: Battery replacement. Sensor placement still matters.
Best for: Norfolk County homeowners who already have a smart irrigation controller (Rachio, Hydrawise) — the wireless gauge can talk to the controller and skip cycles automatically.
Setup 5: DIY Straight-Sided Container
A coffee can, large mason jar, or cylindrical food-storage container — anything with straight vertical sides (not tapered). Mark a ruler in 0.1" increments on the side with permanent marker.
Pros: Free. Already in your house. Cons: Harder to read precisely. Only works if sides are truly vertical (most paint cans aren't).
Best for: Renters or temporary installs. Or as a backup at a second location in a large Norfolk County yard.
Placement Rules (All Five Setups)
Mount any rain gauge:
- 3 feet above the ground (avoids splash from below)
- At least 4 feet from any building, fence, or tree (avoids shadow and splash from above)
- In open lawn or beside a flower bed (not under eaves)
- Visible from a window (so you actually check it)
A gauge mounted under a tree under-reads by 40%. A gauge against a south-facing wall over-reads on splash. Place it somewhere boring and open.
Reading Rules
- Monday morning: read accumulated rainfall since last reading. This sets your week's watering decisions.
- Friday morning: read again. If 0.5+ inches accumulated since Monday, skip Friday's planned watering.
- After heavy storms: empty the gauge so the next event measures cleanly.

What You'll Need from Ottr
The rain gauge itself you'll buy at hardware. But the watering decisions it informs apply across most Ottr materials:
- Topsoil Loam ½" Screened — for thin lawn fixed (½ yd per 1,000 sq ft)
- Compost — top-dress to improve water-holding
- Hardwood mulch — 2-inch beds keep moisture in once you've watered

The short version: $5 fence-post tube wins for most Norfolk County yards. Mount it, check it Monday/Friday, skip watering when it rained.
