Free Michigan and Great Lakes Tools

Live maps, forecasts, planners, calculators, and field guides built by Chris Izworski.

Chris Izworski builds these free tools to answer practical questions: Which Michigan–Ontario border crossing is shortest right now? Can I cross the Mackinac Bridge easily? Which ships are near the Soo Locks? Is the Au Sable fishable this morning? How much cold has Saginaw Bay accumulated? Where is Michigan fall color peaking? Are the northern lights worth chasing tonight? Where should a day trip go under today's conditions? Everything here is free and grouped by what you are actually doing, from fishing and hunting to transportation, boat watching, trip planning, nature watching, and Zone 6a gardening. Use the finder to search all 36 tools by name or topic, or switch to the in season filter to see what is most useful this month.

The library keeps its existing URLs and is organized so visitors and search engines can reach the most useful live tools faster.

Michigan fishing and hunting tools

Live water and field conditions for anglers and hunters. These pull real gauge, weather, and satellite data rather than repeating generic advice.

Live data
Live conditions for more than 63 Michigan trout rivers: USGS flow, water temperature, and weather, with a daily fly and lure pick for the river in rotation. Updated every morning. Free.
Live data
An interactive map of Michigan trout water color-coded by today's fishing rating and built on live USGS gauge readings, with 310 DNR access points you can navigate to directly.
Live data
A written report on one Michigan trout river each morning: stream conditions, hatch notes, and fly fishing intelligence built on live USGS gauge data.
Live data
A live tracker for Michigan's fall salmon and steelhead runs across seven rivers, including the Big Manistee below Tippy Dam, the Pere Marquette, and the Muskegon below Croton. Live USGS flow and water temperature drive a run status read for kings, coho, and steelhead, with river by river timing, technique, and access. Free.
Live data
Saginaw Bay is shallow enough that wind decides everything, so this answers the two questions that actually matter: which zone is in the lee and comfortable, and which zone the water and bait are stacking onto. Live wind from three NOAA buoys, river flow and turbidity, and Lake Huron water level, across the Inner Bay, Lower Bay, and Eastern Bay. Free.
Live data
A live Michigan deer hunting conditions tracker across four regions, built on the one habitat variable most hunting apps ignore: the corn harvest. Standing corn is security cover, and when it comes down in October the local deer herd reorganizes. Pairs that with live National Weather Service pressure, three hour trend, and wind, plus computed rut timing. Free.
Live data
Michigan ice conditions across six waters, tracked the way ice actually works: as accumulated cold rather than today's temperature. Shows accumulated freezing degree days against a ten year normal, NOAA satellite ice cover, and 54 years of Great Lakes ice climatology. Reports weather and satellite data, never ice safety. Free.
Live data
An interpreted read on the natural year across Saginaw Bay and northeastern Michigan: live river conditions, projected hatches, bird movement, and growing degree days.

Great Lakes water, weather, and boat watching

Border crossings, vessel traffic, wave and wind conditions, water levels, and the maritime history behind them.

Marie International Bridge in the Upper Peninsula. Passenger, commercial and trusted-lane selection, cameras, Ontario approach events, NWS warnings, tolls, observed-versus-typical context, and five crossing-specific search guides. Built by Chris Izworski.
Live data
The official Mackinac Bridge Authority crossing status comes first, with separate northbound and southbound cameras, NWS Straits radar, clearly labeled off-bridge NOAA observations, an hourly Mackinaw City approach forecast, RV and trailer rules, nearby Mi Drive events, driver assistance, tolls, shareable crossing reports, and a vehicle-specific Crossing Confidence label.
Live data
A daily newsletter updated automatically each morning with vessel movements, port reports, water levels across all five Great Lakes, and National Weather Service marine forecasts. Built on live AIS vessel tracking data and NOAA feeds. Free and updated every day during the navigation season.
Live data
A live lake-wide AIS vessel map with one-tap views for the Soo Locks, Mackinac, Duluth, Port Huron, Detroit, and Saginaw Bay, plus nearby NOAA conditions and named passage links.
Guide
The complete history of the Edmund Fitzgerald, the largest freighter ever lost on the Great Lakes. The ship, the final voyage, the 29-man crew with hometowns and roles, the wreck site 17 miles from Whitefish Point, the July 4 1995 bell recovery, the Gordon Lightfoot song, the annual memorial ceremonies, and how to visit Whitefish Point today.
Live data
Interactive live AIS vessel map at the Soo Locks in Sault Ste. Marie, Michigan. Real-time navigation season status, lock dimensions and history, the Poe replacement lock under construction, vessel category identification, and the visitor guide for watching transits at the busiest commercial lock complex in the world.
Live data
Live data from more than 100 NOAA buoys and coastal stations across all five Great Lakes. Wave height, wind speed and gusts, water temperature, and air pressure on an interactive dark-themed map with activity filters for fishing, kayaking, swimming, sailing, and diving. Geolocation-based distance ranking, 5-day sparkline history per station, and conditional cross-promotion to the rest of the Great Lakes tool network.
Live official data
Compare 50 Michigan beaches using active EGLE BeachGuard notices, National Weather Service hazards, NOAA waves and water temperature, and local forecasts. Search, map, sort near you, open a beach detail page, or use the automatically seasonal Best Michigan Beaches Today ranking. The core report stays live all year.
Live data
Real-time water levels for all five Great Lakes with tools built for shoreline property owners: an anchor year comparator, sub-region erosion risk, OHWM and regulatory context, seiche and storm exposure, and a six-month outlook.

Michigan trip planners

Route and logistics tools for a day out or a long weekend, built on real hours, access points, and drive times.

Planner
An interactive map of Michigan's Au Sable River from Grayling to Lake Huron, with 70 verified locations: launches and liveries, fly shops and lodges, state and federal campgrounds including the impoundment camps, scenic overlooks, hiking and Shore-to-Shore horseback trails, and birding hotspots from loons to the Kirtland's warbler. Every card carries live USGS flow and weather, there is a float-time planner for the mainstem and its branches, activity filters for fishing, paddling, camping, birding and more, and notes on the steelhead and salmon water below Foote Dam.
Guide
A planning guide to the Au Sable from Grayling to Lake Huron: the Holy Water and the river's segments, popular floats with paddle times, where to fish for trout, smallmouth, and the steelhead and salmon run below Foote, the state, federal, and impoundment campgrounds, birding from loons to the Kirtland's warbler, and answers to the questions people ask most.
Planner
Start with a Michigan city or ZIP and get three outdoor day-trip plans ranked for forecast, air quality, drive time, interests, kids, dogs, and accessibility. Covers 27 curated destinations, uses live weather signals, requires no login, and does not save your location. Built by Chris Izworski. Free.
Planner
A planning hub for Michigan weekends outside: hand-built guides for paddling, trout, fall color and the northern lights, wine country, and the Lake Superior shore. Each guide routes to the live tool behind it and to real state park and Recreation.gov reservations. Built by Chris Izworski. Free.
Planner
A day planner for the tasting rooms of the Traverse City area, across the Old Mission and Leelanau peninsulas. Choose the places you want to visit and it builds a routed, time-aware loop that respects real opening hours, the time you spend at each stop, and the drive between them, with beaches, hikes, and scenic overlooks woven in along the way. Sample starter days to begin from, a designated-driver mode, a shareable summary you can drop in a text, and a button that opens the whole loop in Google Maps. Built on a verified dataset of 74 venues: 40 wineries, 22 breweries, 7 distilleries, and 5 cideries. Free.
Planner
A logistics-first planner for Pictured Rocks National Lakeshore. An interactive decision tool weighs your time, walking tolerance, water comfort, and who is coming, then hands you the right day: the boat cruise, a guided sea kayak trip, the 10-mile Chapel Loop, or the drive-and-stroll circuit. Covers the honest comparison between all four, the Munising versus Grand Marais lodging fork, reservation-only camping and the six-month backcountry permit window, entrance fees, where dogs can and cannot go, the south-wind biting fly problem, month-by-month timing, and current closures including the Munising Falls rebuild. Free.
Planner
Complete guide to the 1,300-mile circumnavigation of Lake Superior. 31 major stops across Michigan, Wisconsin, Minnesota, and Ontario; freighter-watching notes at every port; three concrete itineraries (7, 10, and 14 days); live water-level data; and an interactive trip planner.

Live data
Forty eight cross country ski trail systems across northern Michigan on one map, from the Vasa Pathway to Black Mountain, covering groomed nordic centers, volunteer pathways, and backcountry loops. Each trailhead carries live snow depth, new snowfall, and temperature, plus a plain read on whether it is worth the drive. Filter by skate groomed, groomed, volunteer groomed, backcountry, and night skiing. Free.
Live data
Morels are triggered by soil temperature, not by a date, and that trigger crosses Michigan south to north over about five weeks. This tracks where the front edge is right now across five regions, using accumulated warmth measured against a ten year normal. Honest about its limits: Michigan has almost no public soil temperature stations, so soil is modelled from air temperature. No identification key and nobody's spots. Free.

Michigan nature watching

Fall color, bird migration, and aurora, each driven by live observation data rather than a calendar.

Live data
Live NOAA SWPC three-day Kp index forecast for Michigan, tonight's viewing odds calculated from peak Kp, the dark-sky locations on Lake Superior and the Upper Peninsula that can actually see the aurora when it shows up, dark-sky park ratings, photography settings, and the geomagnetic storm science.
Live data
Where Michigan's fall color is peaking right now, from the Upper Peninsula to the southern border, built on canopy camera readings and Open-Meteo weather. Region-by-region peak timing on an interactive dark map, a six-day forecast for each area, a color-near-you locator, a trip planner that matches a weekend and a mood to where the color is standing, eleven destination field guides from the Tunnel of Trees to the Au Sable, and a short note each day through the season.
