Tahoe and Fallen Leaf Lake

I've been meaning to dive Lake Tahoe again ever since late Spring, and here it is September again before I actually got around to doing it. Tahoe is only an hour and a half from my house, max, and I should take advantage of going up there much more often, even if there really isn't much to see in the lake. But the breathtaking scenery up there alone is worth a trip, and the water is cleaner and clearer than almost anywhere.

So once I got my dive computer back from Scubapro and my gear was back from the annual service, there really weren't any more excuses to put off a day trip to Tahoe, especially since we wanted to check out our new High Pressure 100 cubic foot steel tanks. We decided on Meeks Bay on the California side of the lake because of its easy access. I prefer the Rubicon site at D. L. Bliss state park, but hefting equipment down from the parking lot to the little beach there is just brutal, and getting it back up even more so. So Meeks Bay it was, and it's always nice there.

We went on a Friday and, worrying about having to hunt for a parking spot with the pre-Labor Day crowd, tried to get there bright and early. It got to be 10AM anyway, but our fears were proven wrong; not a car in the lot and we had the beach pretty much to ourselves. It was a gorgeous day but, this being early September, it was quite fresh and so we waited for the sun to warm things up a bit. The water seemed in the mid to high 60s as it usually is in late summer at Tahoe.

After half an hour or so two more divers arrived and we got to talking as we donned our gear. They were old friends and career military, one an experienced diver, the other having just a few dives. I shared what I knew about Meeks Bay and the lay of the land. We took our time and they were in first. Our new Steel 100 tanks made a good first impression. They had the same circumference as the standard Aluminum 80s we had used in Turks and Caicos, and so there was no need to adjust the tank straps on our BCs. And though they were quite a bit taller than Carol's smaller steel tanks, they were lighter and handier than I had expected. We wore 7mil wetsuits, hoods and gloves, and I decided on 14 pounds of weight whereas Carol took 12 (you need a bit more weight than you'd expect because the lower surface pressure at altitude means the closed-cell foam of the wetsuit expands).

The water was wonderfully refreshing and didn't feel cold at all. I used the Liquid Image VideoMask instead of my Scubapro Frameless. We were about ready to go when I realized that our new acquaintances had some problems. One of them was on his back and calling for help. He did not seem in imminent danger and his friend was closeby, but we hurried over there anyway. He had an asthma attack and could not breathe. He'd dropped his mask, snorkel and weight belt and we recovered that. Fortunately, the attack quickly passed, but that was it for his diving plans. It must be very frustrating to have something like that happen, but certainly better above water than during a dive.

So we finally got ready and... Carol's dive computer errored out. Its battery had been down to the mid 50%s and we had contemplated sending it to Scubapro for a battery replacement, but decided against it since it takes Scubapro weeks to get the computer back. So that came back to bite us. I got back out of the water and to the car to get Carol's backup computer. It's not air-integrated and we didn't bring along a pressure gauge, but since she uses less air than me anyway and we had two big, full 100 cubic foot tanks, we decided to go.

The water was clearer than last year, but not as clear as it had been two years ago. It actually seemed fairly murky to me, though Carol later said it'd been in the 50-75 foot range. The southern side of Meeks Bay is quite shallow for the first ten minutes of the dive or so, barely 15 feet. Then, all of a sudden, you see a steep incline and we worked our way around boulders down the slope. Within just a few minutes we were at 85 feet and I saw what looked like a man-made structure. It turned out to be the wreck of a small motorboat. I didn't want to go any deeper but Carol went down to the boat at about 100 feet and took pictures. The temperature had dropped into the 50s, but it still didn't feel cold.

The steep slope probably goes down to well over 1,000 feet and so the temptation was there to descend a bit more, but we were on Nitrox 32 with a MOD of 116 feet, there wasn't much light, and there wasn't much to see. So we did slow ascent back up to 30 feet and swam around the huge boulders, took pictures of crawdads, and looked at schools of silvery fish shooting around the rocks. Diving is always wonderful, but I really did miss all the plants and life of the ocean. Without it, there is just... nothing.

Technically, things went well. My replacement computer worked as it should, the steel tanks felt good, and I probably would have been fine with 10 or 12 pounds of weight. I had started the dive with 3,300 psi and had 1,500 psi left after a 54 minute dive. Carol started with 3,400 and ended with 2,200. So these tanks are good for two dives.

We had a leisurely lunch at Rosie's in Tahoe City, then decided to check out Fallen Leaf Lake on the way back. Fallen Leaf is just a couple of miles off Route 89 that goes along Lake Tahoe, but the lake level is at 6,370 feet, about 150 feet higher than Lake Tahoe. It's a small, longish lake maybe three miles long and less than a mile wide. The road along Fallen Leaf Lake is very narrow and barely paved, and it can be quite an adventure when someone comes at you. There isn't any public parking either, except for a few spots at the village of Fallen Leaf where we stopped and had ice cream. There's a little marina and a small public beach, and we instantly had a great desire to dive the incredibly clear lake. The guy at the boat rental place said the bottom drops off quickly, with the end of the marina already at 100 feet. It was too late in the day, though, and so we decided we'd come back some other time.
