Summer may be winding down, but the diving is still going strong! We’ve had such a fun summer filled with great dives, familiar faces, new certifications, and plenty of time underwater — and we’re not ready for it to end just yet!

The visibility has been great lately, the water is warm, and Labor Day Weekend is the perfect excuse to squeeze in another dive (or a few 😉).

Grab your dive buddies, pack your gear, and come spend the long weekend with us. We can’t wait to see everyone! 🤿

This group from Missouri Valley Rescue squad came out today for our Thursday underwater cleaning!! Not only did everyone get in some buoyancy practice, but they also gave our favorite underwater attractions a serious scrub down before the weekend divers jump in!!

The fish are thrilled, the statues are sparkling, and the water is warm and clear for everyone hitting the dive site this weekend!

Drop a 🥽 in the comments if you’re diving this weekend to check out their handiwork!

Time To Go Diving!

The water is warm, visibility is averaging 25 -30 feet, and still improving!

Platform photos below were taken this morning!

Late summer and fall are nearly always the best times for diving all year.

We cleaned house this week with some amazing help from Allen & Adrin Jones who brought their high powered
pressure washer and cleaning truck. They bleached and cleaned all of our buildings, picnic tables and docks in one
long hot day. The place looks new again! They were AMAZING! If you need anything cleaned we would absolutely recommend them.
