It’s that time of year again! Everyone’s excited to get back out on the water. As boaters, fishermen, jet skiers and divers we’d like to remind everyone to Please be aware of dive flags and maintain a safe distance. Be careful and respectful to everyone. Our lakes are here for all of us to enjoy. Let’s make it a great, safe, fun summer!!!

WORDS CAN NOT EXPRESS HOW PROUD I AM.
Today I received a call that started with words no parent wants to hear. "John....Is Calvin your son?....He's OK." The caller went on to say. "I just saw him save someones life over by the old Inn on Okoboji."
FROM THE BEGINNING. 17-year-old Calvin Grosvenor was hanging out fishing on the docks at Okoboji Boats when he was approached by his dive instructor and owner of the local dive shop that a man needed a "buddy" to dive with today. The Dive shop owner strongly suggested to the man that he not dive alone even though he was an experienced diver. Its a good thing he didn't.
Calvin and the man went to a popular dive location where the old Inn at Okoboji used to stand. At more than 25-feet deep the man started to convulse and sink to the bottom without his regulator in his mouth. He landed face first on the bottom and Calvin quickly swam to his aid. Calvin forced the regulator back into the mans mouth while purging it to force water out and air into his lungs. The entire time Calvin had to hold the mans jaw shut so the regulator would stay in his mouth... He then had to dump his weight belt...fill his own Buoyancy Control Device...and get the man to the surface from nearly 30-feet down while purging the mans regulator several times on the way up. Calvin got him up....kept his head above water holding his mouth shut swam nearly 100 yards to a dock "Dad...I needed 3-hands"
Calvin got the man to the shore where some construction workers helped lift him onto the dock. There was No pulse and No breathing. Calvin then gave the man CPR until the ambulance arrived. There was a slight pulse and a little breathing when EMT's arrived. The man was taken to Lakes Regional Health Care then transported by helicopter to Sioux Falls.
I am amazed at the level headed actions from my son.
Credit must be given to his dive instructor Jose Barba who taught him how to react in such a situation.
We heard late tonight the man should recover.
Calvin's 18th birthday is in 3-days. I suppose i should buy him a mask, fins and a regulator for his birthday.
Great job today Bud! Love you. So proud.

It was a good day to service diving gear. Installed new batteries in the Suunto Viper, cleaned regulators. Getting things ready for next year or maybe an ice dive this winter. If anyone wants to go, hit me up!

Let’s not forget about the polar plunge! I’d recommend shoes so your feet don’t freeze but other than that your attire is up to you!😉
