Me and a friend spent the afternoon/evening fishing Big Spring Creek and then Falling Spring Branch. Good day on the water overall.

The day started at Big Spring in the afternoon. When we pulled into one of the FFO parking lots it was windy with some rain coming down, but by the time we finished stringing up our rods and started fishing the sun had begun to poke through. The wind remained a problem for the rest of the day into the evening. Temps in the mid 60s felt a little chilly as well.

I had previously fished Big Spring three times and never landed a fish. My friend had been one time and also took the skunk. So when the sun came out and we realized just how low the water was we were discouraged. Nothing was hatching and we saw a total of two rises all day. But in the second riffle we fished my friend landed a tiny rainbow on a caddis nymph. We fished for about and hour, and he had a nice one (12-13 inches) take his nymph but it didn’t hook up. We then headed further downstream and he landed a small brookie. I also got a tiny rainbow. So at least we avoided the skunk on Big Spring. We did spook several nice ones including a 15-16 inch bow that I almost walked past, I would never have known it was there if it had stayed put. All three fish took caddis nymphs on a dry dropper rig. Frustrating creek, but I’m sure I’d do much better in the evening or under cloudy skies.

With a few hours until dark we decided to hit the Falling Spring in an attempt to fish the sulphur hatch. It turned out to be pretty amazing. When we got to the stream in the FFO section the wind was still blowing but we could already see sulphurs flying over the water from the parking lot.

We both fished dry droppers with a pheasant tail nymph and immediately my friend landed a small rainbow. We then spotted a large rainbow that was rising but it spooked before we got a good chance at it. For a short 30 minute stretch, the fish were going crazy rising for sulphurs. I missed several fish over 10 inches but unfortunately we didn’t have any flies small enough to accurately imitate the naturals. These fish were rising to naturals inches from my fly yet completely ignoring my offering. I only landed one small bow on the dry. But after the hatch winded down and the fish quit looking up we landed 6 more fish, all on pheasant tails. Three of them were in the 8-9 inch range. My friend had a nice fish bump a streamer right before dark, but it didn’t hook up. We got some really cool footage of fish rising/fish catches as well

Great day overall, but it was sad to see the water so low, especially at falling spring. Upstream from garman drive and especially into the meadow and up to briar lane is genuinely unfishable right now. Barely any weed growth and super shallow water.
 
All the CV spring creeks water levels are lowering - the water levels look up to the banks but the stream beds are silted in due to less water cleaning them out - every time a development is built in the valley, the wells get dug and the volume of water decreases - Ed Shenk had explained this to me some 15 years ago and I have witnessed it firsthand - sinkholes, road runoff, no till chemicals fertilizer, eroded riparian buffer, etc. etc. the trout manage to hang on for now

Dear JG,

Thank you for explaining what I have witnessed to be the case during my more than 40 years fishing the State College area. Spring Creek is 2/3's it's 1978 size in many places. In some areas it looks to fill the banks but like in the CV region the looks are very deceiving. People familiar with the stream can tell you when you walk alongside it that you are walking over vegetation, and in some cases like Fisherman's Paradise trees, that were once covered with water.

It doesn't take a rocket surgeon to figure out that the same thing is happening in the Cumberland Valley. While there are more people in the CV than the Centre region, we are fortunate locally that the development is spread over a much larger watershed corridor. It will be ruined; it will just take longer than I'm going to be around for to do it.

And so, it goes.

Regards,

Tim Murphy
 
For anyone wanting a visual on how the stream is looking in the fly fishing only sectjon this year, here you go.

This photo was taken today just downstream from springview drive.

It’s shocking how low the water is and how little weed growth there is for late may.


IMG_6923.jpeg
This was the same exact stretch last year. I believe this photo was taken on may 18th, and although it looks better I’m sure people who remember fishing it back in the day will notice the low water.

This was taken looking upstream from the bridge on springview drive. Just a week ago those two logs were not even completely covered by water. It’s really sad.

I’m kind of glad I don’t have pictures of what it looked like over the winter because it was genuinely depressing to look at. Once the weeds grow in this summer (if they even do) the water level will rise but it will only disguise the real issue, there’s barely any water flowing through it anymore

WOW...that section has really changed brother! I remember that being MUCH deeper in the late 80s through the 90s.
 
I stopped at Big Spring today and was shocked how low it was. Many of the undercuts are gone and the identity of the stream just feels different. Very sad considering this has always been very consistent from a flow rate.

Oddly enough I checked USGS and it looks like it stopped tracking in October 2024.
 
What did it look like before the recent rain?
It was a little lower but I don’t think the rain affected it much, which is normal. I think the slight increase in water level is just due to vegetation starting to grow in which is pushing it up a bit. We would need the rain we just got plus 20 times more to even start to cancel out the effects of all the development

It was a good bit deeper 3 years ago when I made my first attempt at fishing it, and that was in the middle of the winter when the vegetation was at its lowest. I know the stream has steadily declining for ages but recently it’s been very rapid. Hopefully these low flows aren’t permanent
 
Are there any quarries near these streams that are pumping groundwater?

In limestone country that is a common problem that impacts base flows of spring creeks.
 
I found some videos I took on January first of 2023. It’s not letting me upload it for some reason but these are some screenshots from it. I believe the year before in 2022 it was similar if not deeper, but that section used to hold a lot of water until very recently. (Springview Drive area)

Here’s another section, I took these next photos standing on top of the old dam right where the old hatchery was, also on January 1st 2023

IMG_6931.jpegIMG_6932.jpeg
Compare that second picture to this recent one below (looking downstream from the old hatchery at a different angle) and you will see the difference. The water was way higher two years ago (during the middle of the winter when the weeds weren’t as thick) than they are now (when the weeds should be thicker and after a wet start to spring)

This was a photo taken just down from garman drive last may.

I don’t have any photos of that exact area this year, but it’s literally a foot deep at max with no weed growth, the only cover for the fish are the handful of bushes overhanging the stream, but there doesn’t even look like there’s enough water under them anyway. This photo was taken upstream from the bridge at garman drive about a week ago.

So even though the flows have always been low, in 2022 through last year it still looked really healthy throughout the entire thing. Now it’s shallow and silted. I’m not sure what’s keeping the weeds from growing, maybe it’s because it’s been way colder than last year but that doesn’t explain why there was no vegetation over the winter like before. I’m no expert but something seems off.

For some reason upstream from Edwards Avenue all the way up to the old hatchery actually has some decent weed growth, but that’s about the only place that has any depth to it besides quarry road. I haven’t been downstream of Edwards Avenue yet because last I heard TU was doing a habitat improvement project down through there, so I don’t know what the situation is with that part.

Have there been any physical alterations? For example, has a dam been removed, or breached? That would narrow the stream and also make it flow faster, which is less conducive to aquatic weed growth than lower gradient sections.

not that I'm aware of, no. And with the low flows, the water is moving slower than ever right now.
