Hey Teresa38, welcome!
We dove at Fisherman's Point Saturday. Horrible visibility -- we sent Richard, my better half, down with the dive flag and actually held the line on the way to meet him. Otherwise, you'd lose your buddy in the murk!
Take a good light and a 5-mil wetsuit, because it didn't get better until 30 feet down. Two weeks ago it was okay at 20 feet. Blame the rain.
The new scuba park is a section buoyed off, just look for the dive decals on the vehicles. The bathhouse is nearby, just up the hill. Camping is all around, and so far every time we've arrived there were swimmers as well as divers in the water. Look for dive flags, since it's popular for instruction.
The entry is the old boat ramp, so it's an easy walk. We have been using the large boulders lining the ramp to gear up, but a tarp or folding chair helps.
To get to the sunken bus, take a heading from the ramp to the tall white buoy marker on the left corner. That's SW. Surface swim out within 20-30 feet of the white marker and decend. The top of the bus is around 17-19 feet (I did my safety stop there), the high end is at 25 feet, the low end is at 34 feet. It's an interesting swim-through, and best of all the bluegills and bass like it. The viz didn't open up Saturday until I was at the open hood of the bus, around 30 feet. Two weeks before I could look in from the back and watch my husband at the side entrance.
Stay around 20-25 feet and aim north along the shore to find a pair of boats, a plaque about the new scuba park, and a single boat. We heard about another plaque at the bottom of a tree out west the bus, at around 60-70 feet, but get good directions from someone who has found it.
Also, Big Daddy's is just outside of the Lake Tenkiller State Park entrance. Great barbeque and onion rings. We often do our surface interval there. We've never gotten airfills there, and I believe they are no longer available.
Gene's AquaPro is at Strayhorn Landing in Gore, and this is where we have gotten our tanks filled. (918) 487-5221
