One would think. The dissolved oxygen problem these days isn't severe....but is measurable. Why the difference between then and now? Someone more knowledgeable than I would have to tackle this one. Perhaps it may be connected to the fact that back in the day there was consistent and meticulous channel maintenance performed by the mill owners(?).

The lack of trees in the old photos of Cumberland Valley limestoners back in the day is really striking.
Definitely a lot more trees along BS and Letort today.


How good was the trout population back in the day? In the upper stretches? And the rest of the way down? Most of the angling writing seems to deal with the upper end.

And when are talking about "back in the day" do you mean 1970? 1930? 1880? 1840? 1770? It probably makes a difference!

It may be that the trout population in the lower stretches has been low for a long time.

Chaz, wouldn't that take all the fun out of it?

I have heard that too, FI... the mill owners not only did channel work but also would periodically drain their ponds and flush them... in essence giving the stream an enema.


yup the mill pools would have been connected by a series of locks or hatches - some still exist on the man made side streams of the Test and Itchen chalkstreams in England.

they would systematically 'flush' the entire system during a big flood by opening the hatches from upstream downwards in January or February.

if you ever read an old English fly fishing book you'll often read mentions of the 'hatch pool' - often with a big trout trout in its depths.

the rest of the year the hatches were often kept 3/4 closed and the water rushes through and oxygenates the mill pond - often a great spot for a heavy nymph like Sawyers Killer Bug.

in March they would then physically get in the channels and mill pools with scythes and clean out the weed - using it as fertiliser on veggies.

Thats why even though Brown Trout spawn in the fall, the traditional Trout Season doesn't start until April - we inherited the season from England !

troutbert, if you have or can find a copy, the first bit of Charlie Fox's Rising Trout has a bunch of historic blurbs that recount the fishing in Big Spring and other CV limestoners.

And regarding the oxygen issue, with the mill ponds in place, it's possible in my mind that the outlets helped oxygenate the stream since they were basically a chain of small waterfalls churning the water between the impoundments, instead of the long, uninterupted placid flows we've seen during the last few decades...

For what it's worth, historical accounts (things I've read) have said that anglers would travel there from Philadelphia during the late 1700's early 1800's for the fishing, it was that good.
