I decided to spend my Sunday exploring the headwaters of streams that straddle the Tennessee Valley Divide in hopes of finding clear enough water to snorkel and observe Flame Chubs and Rainbow Shiners. As the day progressed i had nearly burned up a full tank of gas while studying the Georgia Gazateer and zigzaging for crossings and access. In the end i was depressed that nearly every site i encountered was green and silty, even those within a mile or so of springheads. However, it was a good snake day, but bad for snakes as 2 of the 4 encountered had been run over or killed. Mostly black snakes with a crazy, thin, checkery, zigzag pattern of cream. I finally came upon a nice graveled run alongside the road that yielded plenty of Creek Chubs, a few Redbreasted Sunnies, little Darters probably Coosa, and a single pretty Rainbow Shiner. The water was very refreshing and cool to my feet and filled with snails and plants but nowhere deep enough to pool and snorkel. I could have thrashed in the plants for more variety but did not want to damage the only "roadside pristine" spot encountered. I coninued to work my way east and began hitting the headwater of the Cohutta but was again meet with fields, farms, chicken houses and more green water. There is just so much development in this area, it is disheartening to see every stream flow influenced by disturbed ground and the resulting erosion.

I zigzagged over to the Conasauga and 411 where thankfully the water was relatively clear and is still one of my favorite waters to visit. The temperature was comfortable and i snorkeled in my t-shirt and shorts for a couple hours and worked a stretch of about 100 yards. Visibility was about 10' in the low shadowed light. Many of the stones were covered with a spring green growth of a plant. Most of this river's watershed is forested and it shows. Still tho, from 411 and up several miles, the river adjoins agricultured fields and there has been high erosion events during big rains turning the water opaque.

Sunday saw...

Blacktail Shiners, elegant males in their prime working the fast waters.

Alabama Shiners doing the same and with handsome colors and hot white tubercules.

Tricolor Shiners, a few with their dorsal flags pronouncing their namesake.

Blue Shiners, a few males in nice color and displaying near submerged structure.

Lots of silvery shiners! Coosa? My eyes go buggy trying to keep up with all the fast motion.

Mobile Logperch flipping stones, calmly by my side.

Bronze Darters, Holiday, Blackbanded, Greenbreast. Speckeleds. Coosa.

Hogsuckers, Stonerollers.

Southern Studfish in the sandy shallows. Washed out colors.

Nervous Drum, Redhorses, River Redhorses. Ive never seen so many River Reds. Some must have been 30" long, tho it is hard to tell while snorkeling true dimensions. I counted 7 resting beneath me at one point. They are not as skittish as the other Redhorses and will allow a fairly close approach.

Redbreasted Sunfish. Probably Longears among them.

Shadow Bass guarding his nest. Coosa / Redeye Bass and Bass bass.

Ive been here a bunch of times and was not so interested on specie count so began to play with my Dad's underwater camera. Its an Olympus Stylus 790 SW, very fast and responsive compared to my old landbased coolpix. Ive been trying to get a hang of the features, various options and controls with only some success in the cement pond. Even harder In the Conasauga, trying to stay oriented in the current, not stirring up debris as the flash seems to bounce off any suspended matter in the water turning the picture white hazy. I can get a beautiful picture of something not moving, such as the clean substrate in crisp, nice color and high resolution. But add a speeding Shiner, click click click and hope you can catch it, and then it will likely be blurry. I deleted 90% of the shots and kept about 15 to study as the camera seems to have a pic memory allowing me to review the settings for each picture. Here are a few, i wish they were better and will continue practicing. I enjoyed the activity and will try again with batteries fully charged as i exhausted them on this first excursion.

Alabama Shiner, burning bright and hot blurred in the flash.

Mobile Logperch turning stones and keeping one eye on the big fish.

Some of the nice green vegetation. River Weed i believe.

River Redhorse, note those bright red fins. They are big fish! Protected in the Conasauga.

Greenbreast Darter. I followed this guy a long time and he would never allow me to get close for a natural shot. They seem to spend most of their time peering out from under rocks in fast riffle runs.

Awesome, Casper! Sounds like you had quite a time. I'm jealous of you getting to see blue shiners. Those are nice pics, too. It's hard to stay steady while in the current trying to get decent pics. And yes, that is riverweed - Podostemum.
I am quite jealous indeed!
Thanks for sharing.

A fun day, I'm sure. Commercial sized poultry houses, as usual, are the kiss of death for local streams. If you examined creek water from near poultry farms back in the lab you would also find that the creeks are loaded with multi-drug resistant strains of bacteria due to the overuse of antibiotic drugs. It's scary stuff that will eventually catch up with us, kinda like coal ash.

You should have made it down for the South Chick Seine Uncle Willie. You would have enjoyed it and are certainly close enough. I get up towards Knoxville a bit and we could meet somewhere the water is clear. Citico is nice. Im going to get out again this weekend, probably the Ocoee to see what survived the silt kill.

Blue Shiners are pretty easy to encounter. They like the calm vegetated water it seems to me. 3 great shiners in the Conasauga... The Alabama, Tricolor and Blue. Those Blacktails sure were pretty yesterday. Ive never seen them so elegant.

Casper,
I may have to take you up on an offer one of these days. The grad students I am working with have mentioned that we need to take a snorkel trip one day - that doesn't involve 'work'. We have mentioned Citico, and elsewhere in the Conasauga, but we just haven't made serious plans. If we do I will let you know.
Lately, weekends have been crazy busy. But if you ever make it up this way, give me a holler. Also, I will run it by my co-workers tomorrow, and if they are interested and not busy, maybe we will join you this weekend. (It may be a long shot since we are pretty much always on the road and tuckered out from swimming and shocking)
Maybe it'll work out!
