Sample report: sparse rangeland

A real report for rangeland north of Ola in Gem County. Only four wells were on record within a mile, so the search widened to three miles — and the report says so, because wells that far away tell you less. This is what thin data looks like when it is reported honestly.

3 things to check before you close

Ranked by how much is at stake. Each one names who can actually answer it.

  1. 1Check this

    Septic here is limited by steep slope and shallow bedrock

    Soil survey records for Brownlee and Rainey soils, 12 to 30 percent slopes flag 4 limitations for a conventional drainfield: seepage risk, slow percolation, steep slope, shallow bedrock. Limitations of this kind are the ones that most often push a site from a conventional system to an engineered one, which is a substantially different cost.

    What to do: Ask what setbacks from wells and surface water apply on this soil. Southwest District Health decides this after a site evaluation - a soil map cannot.

  2. 2Check this

    Nearby well depths vary widely — 72 to 610 ft

    Wells within 3 miles range from 72 to 610 ft, an 8x spread, with a median of 250 ft. Drilling is priced per foot, so that spread is the difference between a routine job and a serious one. A single quote will not capture the risk.

    What to do: Get written per-foot quotes from at least two licensed Idaho drillers, and ask each what depth they are actually hitting in this area right now.

  3. 3Worth knowing

    Few wells on record close by

    Fewer than five wells were on record within a mile, so the search widened to 3 miles. Wells that far away say less about this parcel than neighboring ones would.

    What to do: Weigh these figures accordingly, and lean harder on a driller who works this area.

This point falls inside assessor parcel RP10N02E074800. Its mapped area works out to about 273.94 acres. That figure comes from the county assessor polygon, which is maintained for taxation rather than for conveyance - only a licensed surveyor establishes real boundaries and acreage.

Well depth is how far the driller went in total. Depth to water is how far down water was standing when the well was finished — it is usually far shallower than the well, and it is not how deep you would have to drill. Yield is gallons per minute the well produced on the day it was tested.

What the closest wells show

The closest 3 wells on record sit 0.3 to 0.6 miles away. They were drilled 400 to 610 ft deep. Water was standing 40 to 167 ft below the surface when each was finished. They reported 1 to 70 gpm. All of them were located from a section description rather than a survey, so the distances above are approximate.

What limits these numbers

  • 35 of 45 nearby wells were located from a section description or a digitized map rather than a survey, so their distances are approximate - a well shown at 0.3 miles could be a quarter of a mile either side of that. Wells located this way often share a section corner, which is why some map pins sit on top of each other.
  • 8 of these wells were drilled before July 1987, when reporting became more consistent. Their records are more likely to be incomplete.
  • Fewer than five wells were on record within one mile, so the search was widened to 3 miles. Wells further away say less about this parcel.
  • IDWR records contain most well reports from July 1987 onward. Earlier records are less complete, and some wells were never reported.

Typical local costs

What getting water out of the ground here is likely to run.

Drilling a well at this locationestimate

$8,800 – $15,000

at the 250 ft median depth of the 33 nearby wells that reported one

Most wells around here land between 100 ft and 400 ft, which puts the realistic range at $3,500 – $24,000. Budget for the top of that, not the middle.

Borehole only — excludes casing, pump and pressure tank, electrical and trenching, permits and site work. Median depth of 250 ft from 33 nearby well records, multiplied by a published statewide rate of $35-$60 per foot. Borehole only.

Water rights and irrigation

What water is already claimed on this ground, and how old those claims are.

No recorded water right lists this point inside its place of use. That is a real answer, not a gap - but it describes the IDWR record only. It does not rule out a right that is recorded differently, and it says nothing about whether a domestic well could be drilled here, which Idaho allows without a water right in most cases.

Soils and septic screening

What a septic drainfield here would have to overcome, and what that adds.

Dominant soil: Brownlee and Rainey soils, 12 to 30 percent slopes · septic suitability Very limited

Why it is limited — and what to ask about each

Nearly every Idaho soil rates "Very limited" for a conventional drainfield, so the rating alone tells you little. These specific limitations are what change the cost.

  • Seepage risk

    Ask what setbacks from wells and surface water apply on this soil.

  • Slow percolation

    Ask whether a larger drainfield is needed, and what that adds to the install.

  • Steep slope

    Ask whether the slope here requires pressure distribution rather than a gravity drainfield.

  • Shallow bedrock

    Ask how much depth is available above bedrock, and whether fill or an engineered system is required.

Soil componentShareSeptic rating
Brownlee60%Very limited
Rainey35%Very limited

Soil survey maps at roughly 1:24,000 — a map unit covers acres, not a drainfield. Only a site evaluation by your health district decides what can be permitted.

Flood zone

Whether FEMA maps this ground as flood-prone, and what that means for a loan.

We could not reach FEMA. That is not the same as this parcel being outside a flood zone - please try again.

Areas of drilling concern

Whether the state imposes extra well construction rules on this ground.

This point is not inside an IDWR Area of Drilling Concern, so no additional well construction requirements apply on that basis.

Who to call next

The people who can answer what public records cannot.

  • A licensed Idaho well driller

  • Southwest District Health

    Permits septic systems in this county and can tell you what site evaluation is required before you buy.

    208-455-5300 - https://phd3.idaho.gov

  • A title company

    Confirms water rights, easements and liens, and what actually conveys with the parcel.

  • A licensed land surveyor

    Establishes real boundaries and acreage. Listed acreage is often approximate.

  • County planning and zoning

    Confirms permitted uses, setbacks and whether the parcel can legally be built on.
