What is OHAC?

Orchard Hills Athletic Club (OHAC) was established 60 years ago as a community pool on the Northeast side of Ann Arbor. We have two pools, OHAC Pool (2300 Yorktown Drive) and Dolfin Pool (2050 Prairie St). We offer extensive youth water sport instruction (competitive swim and dive teams, water polo, group swim lessons) and adult recreational activities (lap swimming and water aerobics). OHAC membership provides additional access to the pools for open swim and private parties, private swim lessons, organized social events, and discounts on club activities. Membership also supports the mission and sustainability of the pools. We are a 501(c)(3)non-profit organization run by community volunteers.

Lap Swim at Dolfin: One lane is always available during Dolfin open hours and can be reserved in Membersplash. You're always welcome to use this lane to swim laps if it's open, but online reservations take precedence. Starting June 10th we also have early morning lap swim available at Dolfin from 6:45am-8:45am. These are reservable in 30 minute blocks through your Membersplash account.

Membership FAQs

How are membership rates determined? The OHAC board approves an annual budget.  Through this process, we factor in the fixed costs of operating and maintaining the pools, labor cost of staffing the pools, historical membership levels, and the prices of competing pools. By members agreeing to volunteer, OHAC is able to keep the costs of running two pools as low as possible. 

Who can be on my family membership? Immediate family members in your household and caregivers if applicable (see below).

Can my caregiver be included in my family membership? If you have a caregiver for the summer, they are welcome to bring your children as your surrogate. Please include their name along with your family membership application. 

Can I get a discount for when I go on vacation? We don't offer vacation discounts, but in 2024 we have half season memberships available which are valid from either Memorial Day - July 15th or July 15th - Labor Day.

If I purchase an individual membership, can I go to the pool with my child? Each person that goes to the pool must have a membership, or be a guest of a member. If your child is 12 years or older, you can purchase an Individual membership on their behalf.  Depending on the number of people in your household, you should consider a two-person  household or full family membership.

Do I have to purchase a family membership if my spouse or I do not swim/go to the pool? If you have more than one child it is more cost effective to purchase a family membership. Family memberships are not priced by number of family members or how often individual members go to the pool. Those factors would be impossible for OHAC to manage. 

Can my child join the swim/dive teams if we are not members? Yes!  Non-members are welcome to join our swim team, but OHAC members do receive a discount (plus perks like private pool rentals and discounted swim lessons!)

Who qualifies for a two-person household membership? This was formerly the “adult couple” membership, but we wanted to broaden it to include any household type limited to two people ages 12 and up. This is not intended for a household with 3+ people where only two household members wanted to join.

Having trouble purchasing a membership online? Please email membership@ohacpool.org

What's your guest policy?

Non-members of OHAC are welcome to visit the pools as long as they accompany an OHAC member. If you want to purchase a Guest Pass ahead of time, you can do so in MemberSplash by selecting "Make a Payment" from the "Payment" drop-down on your member homepage. Otherwise, we will bill your member account for a Guest Pass at check-in when you arrive at the pool. We are doing our best to go cashless which we hope will be easier on everyone!

Each Guest Pass costs $5 and is valid for one (1) visit to OHAC Pool or Dolfin Pool. If you leave OHAC to go to Dolfin accompanied by the same guest, you would need to purchase a new guest pass. 

Each guest is limited to ten (10) guest pass purchases per season. For example, if I want to bring my neighbor Bob to the pool, he can only visit 10 times per season. There is no limit on the number of different guests you can bring to the pool (i.e. teammates, friends, family members).

Do you close the pools for weather?

Safety is our #1 concern. The pools will be closed during thunderstorms and will reopen 20 minutes after the last occurrence of thunder or lightning. The pools will also be closed if the weather is too cold (less than 60 degrees). Weather decisions are always at the discretion of pool management. Feel free to call the pools to check whether or not they are open if the weather seems questionable.

How does volunteering work?

Our community runs on volunteers! When you buy a membership, we ask that you or someone in your membership household agree to volunteer during the pool season (~3 hours is the general guideline). In return we offer a $75 discount on your membership for volunteering.

You can choose how and when you volunteer each season. We reach out via email to members with volunteering opportunities throughout the summer. Some recent volunteer opportunities include: opening/closing the pools, snow shoveling, landscaping, helping out at social events, painting, and much more.

We do not require our 60+ years old members to volunteer (although many of them do!). OHAC is happy to sign off on group volunteer hours for high schoolers.

If you have any questions, please reach out to our Volunteer Coordinator at cynthia@ohacpool.org.

When can I swim laps?

At OHAC Pool: Daily from 4:30-5:30PM. OHAC Pool will have three (3) lanes available from June 17th-Labor Day.

At Dolfin Pool: One lane is always available during open hours during the summer. This lane is limited to ONE swimmer. 6:45AM-8:45AM, Monday-Friday Dolfin will have five (5) lanes available starting June 10th. 

Rules for Lap Swimming: Lap lanes should be reserved in Member Splash from your account homepage under the "Reservations" tab. Lanes will open for reservation one week in advance. Up to 5 advance 30-min reservations can be made per week across all slots. Lap lanes can be shared by two swimmers. Reservations can be back-to-back if an hour of lap swimming is preferred. If you don’t show up within the first 10 minutes of your reservation, you can lose it if there is another swimmer on standby to swim. Anyone is welcome to drop-in to swim laps if there are lane spaces available, but reservations take precedence. 

What are the pool rules?

1. No talking to lifeguards while they're on stand. Lifeguards are there to monitor pool safety, and distracting them can be dangerous for other swimmers in the pool. If you need something from a guard, there's always a second lifeguard working off the stand who can assist you. Also - just a reminder that our lifeguards are mostly teenagers, so please treat them kindly as they learn and grow. If you have a question or issue that a lifeguard can't resolve, please reach out to our pool manager Sarah

2. Food must be kept to the eating areas (picnic tables at both pools)

3. Children 12 and under must pass our deep end test before they're allowed to enter the deep end at either pool. When your child is ready to take the deep end test, they should ask the off-stand lifeguard to take the test. 

4. No glass containers are allowed (broken glass and bare feet are a bad mix)

5. Showers are required prior to entering the pool

6. Non-toilet trained children must have an appropriate swim diaper to swim in the pool.

7. At OHAC: Members with strollers or using assistive devices may use the stroller door. All other members must enter through the shower rooms.

8. At Dolfin: No back jumps, flips, inward or reverse dives off diving board

9. No running on the pool deck

10. Children under 12 years old must be accompanied and supervised by an adult at all times while at the pools.
