Saturday would be a long day, starting off in preparation on Friday afternoon with loading up my boat(Miss Jellyfish) and the majority of my cave diving gear. Saturday rolled around early and I was on the road around 5:45AM heading into Florida. I met up with cmufieldhockey8 at the Flagship/DairyQueen in P'Cola around 6:30 to fill up with gas. The sun was coming up about that time. It promised to be a clear day, a bit chilly at first(upper 40sF that early), but supposedly warming into the upper 60sF(and maybe around 70F).

The ride to New Hope(where we'd be launching) was pretty uneventfull and we arrived at the boat launch sometime around 9AM, I'd imagine. We were the first at the launch and the boat went together without a hitch. cmu and I loaded up and headed down river.

Ebro Blue Spring

After 5-6 miles of running down a flooded creek and a fast moving river(levels are high since rains early last week), we made it to the spring run. There were no obstacles in the run as the water levels were so high that we could boat through without much trouble. High ground was scarse as the flood plains were inundated. Water in the run turned from coffee light brown, to tea brown, and eventually a milky green color. Ebro Blue Spring's(also known as Washington Blue Spring Choctawhatchee) basin was green and milky as well. There was still a boil present however, so we tied off to a submerged stump and began gearing up. After a quick drop down to the cave entrance(not really much of a cavern here), the water cleared up quite nicely within the flow(50-60') - which was strong, but managable. I made it inside without the need to pull on the rope. After finding the beginning of the cave line, we headed back up to the surface to talk about conditions, what we'll expect to see, and go back over our dive plan and limitations. cmu and I weren't diving to see how far we could go and weren't interested in pushing any limits as this was new cave to both of us. There wasn't really any white limestone to speak of, all of it was stained a rust colored red/brown. So was the line, which was basic explorer line, knotted every ten feet and had an occasional survey tag and even less occasionally a stained line arrow. Tons of formations throughout the cave and lots of black walls as well, talk about suck the light right out of the water... Lots of fossils in the walls, anywhere you'd look. We took an incredibly slow pace and turned on my 1/6ths. Once we turned, we made our exit in visibility around 10' due to the percolation from the ceiling raining down and being sucked back towards the entrance with the flow. We drifted out and I had a max depth of 72'(average depth was much shallower) for a dive time lasting 59 minutes. Definately my favorite cave to date, untouched formations and you can forget about crowds!

Duck Spring

So after a very successfull dive at Ebro, we decided to try to find another spring I had read about(and verified having atleast a cavern by another diver) not too incredibly far off. We didn't have our hopes up, especially with the river levels so high, but we gave it a whirl regardless. We found a spot that looked like it could be the spring, hopped in the water to find nothing, and continued further up the run to see if we could find the real thing. After a bit of tooling around(and a wood duck sighting!), cmu and I found a promising run that lead us to the spring. It was in the middle of a large floodplain but had a semi-circular berm around one side. Not sure if the berm was natural or manmade. We pulled up to the berm, which was an island with the current water levels, and tied off to a cypress knee. The water was clearish and green, probably 20-30' of visibility within the basin before we stirred it up while gearing up. The basin dropped down steeply to an open bore hole about 10' wide that narrowed to 4-5' at a cavern entrance. The cavern was really neat, lots of formations and it was about 20-25' wide and about 45' high and basically cylindrical. Percolation was a problem here as well so visibility dropped from ceiling to floor, down to 15'ish. We found three lines from the cavern entrance that lead to the bottom of the cavern at about 74' where a cave started. The line didn't go into the cave and there was a strong flow with lots of sand pushing out, blocking visibility too far within. We didn't see any line inside the cave and hadn't had any information of there being line within. The passage starts off, and possibly doesn't get larger(?), relatively small but backmountable. However, it wasn't large enough to turn around in and we weren't interested in having to back out of an unknown distance so stayed within the cavern zone. Light was visible via a pale green glow even from the bottom of the cavern. Vertical marks ran up and down the cavern walls formed from sand continually falling in the same area over time. Turtle carcasses were all over the bottom of the cavern, several of them. There was another point of flow towards the top of the cavern, on the opposite side of a large sand dune that was about 3-4' wide and circular which dropped straight down. It had several limestone outcroppings within that would make traveling this tunnel hard/impossible without damage to the cave. There was no line here either and flow was strong. Very nice cavern with potential of nice cave - just need more info before proceding. Max depth of 74' for 48 minutes.

It was a slow ride back to the boat launch while fighting a strong current up the river, but we made it back and packed before it was dark. Hit up Dee's in Vernon for some grub and headed back West. Got a call from some other ScubaBoarders that were on the AL gulf coast having drinks and tried to meet up with them. By the time I made it to FloraBama, algulfdiver and his wife was there, but none of the others in that party apparently felt up to a later night - LOL. I made it home a little after mid-night, another great day of diving!

Never has my signature been so true, as long as you're ready for a bit of an adventure.
 
Those pictures turned out great! Great report!

Here's a chunk of what I put in my dive log. This dive seemed to deserve greater attention then the usual dive:

It was a pain to get in- had to go single file and almost straight down. The hole was small so you had to go head first which means upside down and with doubles and it was very unsteady feeling for me. And the flow was kicking!

I know the flow was down but man it was tough. I was clinging to rocks and logs not all of which were stationary and working pretty hard to get in but the line was right there, couldn't miss it. The plan was go about 500 feet (Bug was gonna count knots that were every 10 ft) and if we get to 90 ft depth turn around. Also turn around for other stuff like approaching deco, eerie feeling, silt, and most importantly silt from percolation.

We got in, and it was very apparent not too many people dive here.

EVERYTHING was brown. Not marked, no chucks of rock taken out. I've never seen a cave so brown. The line was brown, and everything was just covered in dirt. The cave itself was very pretty. Rock formations EVERYWHERE. It wasn't just a smooth tunnel at all. The bottom was sandy and not clay or anything so that was good for us. We start swimming and I see a huge cloud of brown and small chunks of rock just raining down on me from the ceiling and I thought for a second that Bug kicked the ceiling, but as I watched more it was every time his bubbles hit the top.

It totally felt like virgin cave and it looked like it was covered in crystals of goethite which isn’t seen too often (I read it's because once touched it crumbles and becomes silt.) I looked back a few times to make sure we weren't creating a siltout, maybe 20 feet viz. I’m thinking “cool, its not too bad” so we kept going. There was no way I could count the knots so I figured Mat lost count.

It had been surveyed, there were a bunch of tags on the line. and even after wiping the gunk off the tags i could only make out the word survey and then "do not remove'. I tried to figure out our pace by keeping track of time and counting the knots but I had so much on my mind I couldn’t do that also. We went really slow, and turned at 23 min. It was pretty shallow too! Avg depth 47 ft, it was awesome. sooo cool, I had so much fun i started laughing during the dive.

When we turned around to leave the viz was much worse then I remembered it being the few times I turned to look back. Before I was thinking "look, the flow is carrying out the silt" but when we turned around, it was all still there and it was following us out too since our bubbles continuously stirred it. Viz was probably 10 ft on the way out which normally doesn’t bother me, but in a cave it raised the stress level a little bit. It wasn't enough to glue myself to the line but concentration was a must to keep from losing the line since the line was the same color as everything else. We drifted back; it was like floating through a blizzard.

The backscatter was bad. Maybe it was psychological, but I found that stretching my arm out to the side with the light helped me see better. I was glad to see Mat’s reel which told me we made it back. We exited quicker then we did going in. The safety stop was a bitch as it was right outside the opening where the flow was strong but I did find that dumping most of my air helped with that as the flow was coming straight up.

We were so giddy. The basin was too murky to take pics. I had an underwater camera to document but it was too crappy. I could’ve taken a pick just inside but i didn't want to have to crawl in again. It totally felt like I was in a virgin cave. It was a little bit of a hike to get there – a few mi on the river but so worth it.
 
Nice report guys. Sounds like a lot of fun!

It was peacefull along the spring runs, until we hit the river, where the water was really pushing downstream - we could barely make progress back up river. It was a quick trip downriver though!

In the caves, it was peacefull on the way in, but far more alert on the way out in the blizzards ;)
