You are now entering the X River Basin...

Back when I was 13 years old, my brother and I thought it was extremely cool when we stopped at the marker for the Arctic Watershed in Ontario somewhere between North Bay and Cochrane. It made it feel like we had gone a REALLY long way when we saw "all streams flow north into the Arctic Ocean."

It's just north of Kirkland Lake.

Ontario marks the Atlantic and Arctic watershed divide at parks like that on Hwy 11 and Hwy 144. I don't recall it being marked on Hwy 101 when I was last there.
Everything flows either into the Great Lakes/St. Lawrence River or northerly, and haven't chosen to subdivide it further.

Ohio does it for the Lake Erie and Ohio River watersheds (basically the only 2 in the state) at the St. Lawrence continental divide. Akron lies on the divide.

Yeah, it makes sense once I thought about it, but I was a little surprised the first time I went south from Cleveland on I-77 at just how close to Lake Erie the divide actually is.

Thanks. It looks a little different now than it did in 1986–back then, it didn't include any French. The images of the moose and the bear look about the same, though.

Out of curiosity I moved the map to Cochrane and I see the Chimo statue looks the same as it did back then except the town's name wasn't there when we visited.

Here's a brief rundown confirming that they're basically intended to increase awareness of the concept and importance of watersheds. As such, they don't have a direct navigational or locational purpose, but their use along the roadside plants seeds of understanding in people's minds as they go about other aspects of life.

Gee whiz information. Just like the divides.

yawn

so I entered a watershed.  I'll just keep driving...

[cpzilliacus]

I think all of this started with the Cheseapeake Bay signs, and I think those were some kind of enviro deal.  Other states saw these and it became a "thing", much like the fundamentally meaningless "Certified Business Location". 

I believe the Chesapeake Bay Foundation had a lot to do with it.

The WV Turnpike signs the "Paint Creek Watershed", which Paint Creek is a rather ordinary minor creek that flows into the Kanawha, which roughly coinsides with the misdesigned dangerous section of that road.  No idea why.

Why not just say Kanawha River Watershed?

I do like Maryland's signage for the "Eastern Continental Divide".  I have not seen such elsewhere.

The Eastern Continental Divide signs are rather common in North Carolina. 

The Tar Heel State also likes to post signs at watershed drainage divides ("Entering Cape Fear River Watershed").

[Mr_Northside]

There used to be signs about entering the Chesapeake Bay Watershed on I-95 near Petersburg, Va. and on I-70/I-76 (Pennsylvania Turnpike) east of the Allegheny Mountain Tunnel, but I believe all of those are now gone.

I could've sworn I saw that sign on the Turnpike last Wednesday while I was heading to the beach (and crossing the bay in question).  But all this reading about it might just be messing with my memory right now.

There is signage for the ECD on US 33 between Elkins and Seneca Rocks.

Indiana marks the north/south continental divide too: https://www.google.com/maps/@41.6346176,-86.2869746,3a,75y,180h,90t/data=!3m6!1e1!3m4!1sz4vrkgK_K5VcHAKASP1L9A!2e0!7i13312!8i6656

Sounds like this is related to Agenda 21.

I-40 westbound just east of Ridgecrest in North Carolina


Thank God the goog doesn't do away with the older SV pictures. There is a tractor trailer parked on the shoulder blocking the sign on the newest one.

[TravelingBethelite]

There's one just like a mile so west of the CT border on I-84 in New York, saying, entering 'Hudson River Watershed'. Would post a GMSV image but my computer isn't cooperating.

On PA 449 south of PA 49, there is a sign (can't really see it here: https://goo.gl/maps/cU1K9) that marks a triple divide...within a mile of here is the source of the Genesee River, flowing north to Lake Ontario and the St Lawrence Seaway; Pine Creek, which flows into the Susquehanna River and the Chesapeake Bay; and the Allegheny River.

[rarnold]

New Mexico marks entrance to new watersheds. The signs even have the name of the river it is a tributary of, like the Canadian River flows into the Arkansas River.

[Pete from Boston]

I have seen "Eastern Continental Divide" marked where crossing from the basin of the Gulf of Mexico to that of the main body of the Atlantic.

Never seen one that marks a divide between the St. Lawrence and the main Atlantic.

I assume that watershed signage started with a few concerted efforts to bring attention to particularly distressed bodies of water (like the Chesapeake Bay), but as more watersheds were signed, the signages meaningfulness to the public diminished.

But I never got the point behind the "No Dumping - Drains to Bay"  signs on storm drains or "Water Supply Area - Spill Response 911"  signage I've seen in PA. Dumping any kind of hazardous waste is not acceptable anywhere, regardless of whether the drain empties in the bay, into a creek, or into a municipal waste water system. And if I see an overturned tanker, I'm calling 911 under any circumstance.

The storm drain exhortations build passive awareness that dumping coolant, etc., in the drain is a bad idea.

As for watershed signs, I never quite got Connecticut's "Public water supply watershed area" signs.  How should I drive I-91 differently in rhis case?

Enough people are dense enough to not call for more minor things. Even a leak could cause major issues.
