Well slap my tale. the noisy part is they detect the differential motion of water with their whiskers to find leaks in the dam and plug them. They have to be on the calm side to feel the very subtle flows differentials. Its fascinating to go to their dens in winter and see the little hole where the warm air from the den escapes. There are usually tracks of Bobcats, coyotes, and fox leading to the small breathing hole where they can sniff but not reach. The longest dam I have dealt with was a half mile long and backed water up through a small forest which was fun to paddle it.

Well, maybe that was an old married beaver's tale...
:)

Beavers are very smart and only build where there is food. that is not on steep banks and narrow fast moving streams. they build where there are easy to ascend bankings and lots of young woody material along the shore. Calm waters are easy to swim in both directions. I have been involved with beavers in various locations from Maine to Montana and Washington. They like a stream that can be damned and provide food then abandoned and move to a new site while the vegetation returns to the old site. I'll save the story of how beavers drown Coyotes for another time.

oh; well, "never mind." (like Emily Litella) -- j

I should have said I knew OF them.

... one of VERY few "beaver lessons" I could possibly pass on to this group... :)

And I'm OCD and ADD on that stuff, so sometimes I can't keep my mouth (typing) shut, too...
:)

then you must have known my friend Sylvia Parker!
she was a year ahead of me in Everly Brothers High
and befriended me even though I was a nerd.
she was a very sexy woman. . remember? -- j

p.s. west high in knoxville did see the E Bros
for awhile, before they were famous.

thanks for the beaver lesson!

My proofreading missed 'is' replacing 'if'' in my reply, too. QC is definitely lacking ;^)

I knew everyone except Sylvia and Ian.

And ignore the lousy proofreading and writing skills, too...
And lack of accurate description... is "flowing north" defined by 'mouth is north of source'? Implicit, but not spelled out... I'm a little disappointed...

to wit...

THE FACTS: Unless the land it totally flat, rivers of water run downhill. The vast percentage of rivers on the planet flow in
a southerly direction because the source (usually in the mountains) is to the north of the mouth.

If the source of a river is at a higher elevation than the mouth, that river will run from the source to the mouth. However,
if that (higher) source is to the south of the mouth, that river will then flow to the north (downhill).

Below is a partial list of rivers (length listed when known) that do just that. We haven't listed rivers that run to the northwest,
or rivers that don't meet the exact requirements...

>>>>>> "Unless the land it totally flat, rivers of water run downhill."

--"is"? and "You're shitting me, right?"

yessir, we're a curious bunch here in the gulch!!!

the neat thing is that we learn from one another,
about Franz Peter Schubert and Sylvia (plus, do you remember Ian and
Sylvia? ... https://video.search.yahoo.com/video/pla...)
-- good innocent fun!!! -- j

p.s. that's a live version, not the "hit."

You're getting too erudite. But I have used that "Who Is Sylvia" line several times and this is the first time anyone has bothered to investigate where it came from.

I admit I didn't get out my atlas and check to see it those match your criteria ;^)

okay, here goes:::

I learned something new....Thanks...

The Eel River in California flows North!

Very good.
I was referring to the title of a song by Schubert. But, I'll take your reply instead.

ok.

the Ob, the Yenisei and the Lena Rivers in Russia
flow north into the Arctic ocean. -- j

here's Sylvia:::
