Shipped. CFS / gauge feet toggle, defaulted per river.
The community-built outdoor app
You request it. We build it.
Baseline Maps is shaped by the people who use it every weekend. Tell us what's missing — a river, a map layer, a fix — and watch it ship, usually within the week. 1,100+ rivers, 1,339 hunting units, one price.
Built by request
Every screen has a story. Most start with someone’s feedback.
We don’t have a roadmap committee. We have a Discord, a feedback box, and a list of people who voice-memo us at four in the morning. Here’s what we shipped recently because someone asked.
02
Driftline · steelhead angler
“Water clarity is critical for steelhead. Add turbidity where USGS publishes it.”
Shipped. Turbidity readings integrated from every USGS gauge that publishes them.
03
Driftline · Canadian user
“Show Celsius for Canadian rivers — we read conditions in C, not F.”
Shipped. Celsius display option, available across every temperature reading.
04
Driftline · Niagara angler
“Niagara is a world-class fishery. It should be in the app.”
Shipped. Niagara River added to coverage. Same week we added Michigan and Ontario stations from other requests.

From the field
“I used to check five apps before every trip. Now I check one — and it tells me things the others never did.”
Steelhead guide · Yakima, WA
Driftline Mode · Fishing
Know the water before you load the boat.
Real-time CFS for 1,100+ rivers. Water temp, gauge height, tides, NOAA buoys, hatchery returns. Set your fishable flow window and we’ll tell you when it hits.
Built for the field
Every screen reads at a glance — sun, cold fingers, glove on.
River intelligence
Live CFS, water temp, gauge height, and 30-day trend for 1,100+ rivers. Set your fishable window once.
GMU & land ownership
1,339 units across 9 Western states with parcel-level public vs private boundaries. Season dates by unit, and coverage keeps expanding.
Offline topo & satellite
Topo, hillshade, satellite, parcels. Download regions to your route. Works without service.
Tides & NOAA buoys
Tide curves with solunar overlay. Wave height, swell period, water temp from every NOAA station on the West Coast.
Regulations, parsed
WDFW, ODFW, IDFG rules parsed by river and GMU. Emergency rule changes pushed within hours of agency posting.
Catch & hunt journaling
Log catches and stand sits with photos, weather, and conditions. Private by default. Export anytime.
In the field
Real screens. Real trips. Real hands.
These aren't mockups. The app, the people, the conditions — all real, all from this season.
Driftline · West Coast salmon trip
Wave period and swell forecast next to the rods. Trip-go decision in one screen.
Ridgeline · WA DNR land lookup
Tap any parcel. Designation, manager, hunting allowed status — at a glance.
Driftline · ocean charts
Wave height, barometric pressure, swell — observed and forecast on the same chart.
Ridgeline · golden hour scout
Mode toggle keeps the same map but switches the data behind it — fishing to hunting in a tap.
Driftline · Redshift mode
Pre-dawn launch or late return — toggle Redshift and the whole app reads in red. Easy on the eyes, preserves night vision, kills the blue light that wrecks a 4 a.m. start.
Ridgeline · opening morning
Two hunters, one app, one shared waypoint set. The plan happens at the tailgate.
Ridgeline Mode · Hunting
Walk in with the unit, the boundaries, and the weather already in mind.
GMU maps, land ownership, public vs private boundaries, season dates, draw odds, weather windows, offline topo and hillshade for the backcountry.
Maps
Every layer that matters. Nothing that doesn’t.
Topo, satellite, hillshade, parcels, public-land boundaries, MVUM roads, lake bathymetry. Sourced from USGS, NOAA, state agencies, and county GIS — never resold marketing data.

I have a few other apps for fishing and this has them all beat. The sheer amount of data provided is seriously impressive. Every update I find myself opening the app and trying to figure out what new feature was added.
Easy to use and keeps improving

I love that you can actually reach the developer and give input to help make Driftline better. That makes the app feel more personal and connected, like the people behind it really care.
Best app for 2026!

The company being quick to do updates and corrections when errors or bugs are found is why I’ve stuck with this app. I am finding myself using this app quite often to check river access and conditions.
Amazing app

★★★★★
I have been here since the beginning and the changes they have made to this app due to user requests is amazing. Day by day it is becoming a 1 stop shop app with features that are actually useful.
Upping the ante, bit by bit!

I’ve been impressed with the ability to gather important data about whether I should get out fishing or not, and especially the ability to set custom alerts. Some of my favorite fishing is very dependent on conditions.
Rapidly evolving like nothing else

This is such a useful app for fishing, hunting, shooting, and anything outdoor related. The thing that really puts it over the top is that if you have an idea or an improvement you just let them know.

FAQ
Common questions.
- What is Baseline Maps?
- Baseline Maps is an outdoor mapping and intelligence app for fishing, hunting, foraging, and offroad use. It combines real-time river flows, NOAA buoy data, tide charts, hunting GMU maps, land ownership, and state regulations into one app — built with input from the people who use it in the field every weekend.
- How do I request a feature?
- Three ways. The in-app feedback box (Settings → Feedback). DM us on Instagram @baselinemaps. Email info@baselinemaps.io. We read every request, usually within a day. If it's a bug, we triage it that hour.
- How fast do you ship?
- Bug fixes ship within the same week. Smaller features ship in days. Larger ones land in a couple of weeks. We tell the requester first when their feature goes live.
- What is a Founder?
- Founders are the original beta users — the people whose voice memos, bug reports, and feature requests shaped the app. We text Founders before we ship design changes and credit them in the in-app Development Queue. It's recognition, not a marketing tier.
- Is there a public roadmap?
- Yes — open the Development Queue inside the app. Every shipped feature, every in-progress build, and every credit to the person who asked. We don't hide the roadmap behind a marketing wall.
- How is Baseline Maps different from onX?
- Three things. Baseline Maps covers fishing and hunting in one app, not two subscriptions. We include real-time water and weather intelligence onX does not. And we ship features the week users ask for them — onX has a corporate roadmap.
- Does Baseline Maps work offline?
- Yes. Download map regions for offline use including topo, satellite, hillshade, and land-ownership layers. Cached data is sized to your route.
- What states does it cover?
- Real-time river flows in Washington, Oregon, California, Idaho, Alaska, Michigan, New York, Ohio, Utah, Wisconsin, Pennsylvania, Nevada, Minnesota, British Columbia, and Ontario. Hunting GMU maps for Washington, Oregon, Idaho, Montana, Colorado, Wyoming, Utah, Arizona, and New Mexico. NOAA buoys across the US Pacific Coast. New states ship when users in those states ask.
- How much does it cost?
- $34.99 per year with a 30-day free trial. No tiers, no per-state surcharges, no upsells.
