You find out the lake after the offer
Listings show square feet and shoreline footage. They don't show that the "crystal-clear" lake turns pea-soup green in August — or that Secchi readings have been trending the wrong way for years.
For lake-cabin shoppers & their realtors
Paste an address — or a Zillow / Redfin listing URL — and CabinClarity tells you exactly which lake you're looking at — along with nine years of water-clarity history, invasive-species warnings, fish species, depths, and direct links to every official DNR report. In seconds, not hours.

The problem
The biggest financial risk in a lake purchase isn't the deck or the septic — it's the water you can't evaluate from your phone.
Listings show square feet and shoreline footage. They don't show that the "crystal-clear" lake turns pea-soup green in August — or that Secchi readings have been trending the wrong way for years.
Zebra mussels cut swimmers' feet and wreck boat motors. Eurasian milfoil chokes shorelines. None of this appears in listing photos — but it's all in DNR records, if you know where to look.
Fish surveys, special regulations, consumption advisories — they exist for nearly every Minnesota and Wisconsin lake. But hunting across five state websites after a 10-hour showing day? Nobody does that.
A street address doesn't say which lake it's “on.” Is it connected to the big one nearby? Is there a public access? CabinClarity answers both before the first showing.
What CabinClarity does in seconds is currently hours of tab-juggling per lake — DNR LakeFinder, LakeBrowser, county GIS, flood maps. The data exists. It's just scattered. We centralize it.
Listings love the phrase “lake access” — but a shared dock two streets away is a very different property (and price) than one with your own shoreline. CabinClarity shows exactly which lake a home sits on, and how it touches the water.
Everything about the water, one screen
One transparent 0–100 rating that blends water clarity, lake health, invasive-species status, and shoreline makeup into a single number — with a full “why this score?” breakdown. Tune the weights to what you care about. And if being able to boat to a restaurant matters to you, the map has you covered — lakeside spots are pinned right on it, so you can see what's reachable.
Zebra mussels, Eurasian milfoil, spiny waterflea and more — flagged at the top so nothing gets missed.
Full species list plus special regs and safe-eating guidance straight from DNR survey data.
Nine years of Secchi disk readings from UMN LakeBrowser's modeled data — charted as a trend, so buyers see whether the lake is getting clearer or murkier before they commit.
Tappable lake polygons. Tap any nearby lake to pull its profile instantly — perfect for comparing two listings in the same area side by side.
Acreage, max depth, littoral percentage, shoreline length — the numbers serious buyers actually ask about.
One tap opens the actual DNR report pages — depth maps, WHAF lake health, fish consumption advice. Every number, traceable.
Turn any lake profile into a clean, one-page summary you can text or email in seconds. Realtors can add their own branding, so every report that leaves your phone looks like it came from you.
Who it's for
Paste the Zillow link the night before a showing. Walk in already knowing the lake's clarity trend, its invasive-species status, what fish are in it, and where the DNR reports live. Ask sharper questions. Offer with confidence.
Run the address between appointments instead of researching all evening. Show up fluent in the lake — not just the lot. Send clients a lake profile along with your follow-up and be the agent who did the homework.
A lake isn't scenery — it's the product. Clarity affects swimming, fishing, algae treatments, dock maintenance, and resale value. Understanding the water isn't extra diligence. It is the diligence.
Realtors who bring lake knowledge win trust. Buyers who ask lake questions negotiate better. CabinClarity puts everyone on the same page — literally, the same phone screen.
