The Linvill family has operated swim clubs in Middletown Township for over 90 years.
In the 1920's Arthur Linvill hooked a scoop to a horse and dredged the pond at the bottom of the hollow that is now known as Knowlton Swim Club. The neighbors loved swimming in the swim hole. After a couple of years Arthur and his neighbors decided to all chip in so they could hire a life guard so it would be safer for the kids to be swimming. This was the beginning of collecting dues for the club. In 1928 Knowlton formed its board of directors and officially sold memberships.
In the early 1960's Knowlton Swim Club had a 3 year waiting list. Arthur and his two sons, Paul and Larry, worked with an architect and designed the award winning facilities of Hidden Hollow Swim Club. Hidden Hollow Swim Club opened in June of 1965.
Hidden Hollow won several awards for its amazing design.
The dive tower was designed to be sure to include women in competition.The 3-meter, 6.5 -meter and 10-meter platform tower is an awesome and unique structure. The 6.5 meter was designed at the 1965 women's diving competition height.
- In 1970 the heated lap pool was added to Hidden Hollow. (It is no longer a heated pool.)
- The lap pool is measured 25 meters by 25 yards so it may handle any competition.
- 1970 began the years of Knowlton's undefeated swim team with Mr. Jones as coach.
- 1971 Fred Phillips became manager at Hidden Hollow.
- In 1980, Knowlton's 25 meter steal pool was rusting through and leaking badly. Steve Linvill looked at the problem and came up with the solution of fiber glassing the entire pool. Knowlton was one of the first steal pools to revert to fiberglass.
- 2012? installed stainless gutters on the clover leaf at Hidden Hollow
- 2014 replaced the dives at Hidden Hollow.
- 2015 we installed stainless steal gutters on the 50 meter pool at Hidden Hollow.
- 2016 Fred Phillips retires as Hidden Hollow's Pool Manager.
- 2017 the dive towers at Knowlton were replaced.
- 2020 we installed stainless steal gutters on the 25 meter pool (lap pool) at Hidden Hollow.
