Field Day 2019!

Saturday, August 3,  2019







It has come to our attention that vehicles have been driven on the grass at Browne’s Field.

With this extremely high-water situation and with all the rain, it is CRITICAL that there are NO VEHICLES permitted on the grass!

Thank you for your cooperation.





Attention Amazon shoppers!

Did you know you can support your Harsen’s Island St. Clair Flats Association (HISCFA) just by making purchases on Amazon, at NO ADDITIONAL COST to you? It’s TRUE! It even works with your Prime membership!

How does it work? Make sure you’re logged in to your Amazon account and then go to smile.amazon.com … now select the HISCFA as your designated 501(c)(3) charitable organization. Then just shop Amazon like you usually do, either by the app or through your browser. The only difference is that you need to complete your purchase through smile.amazon.com, and 0.5% of your purchase will automatically go to the HISCFA!

This small step can make a huge impact. Between October-December 2018, because of Amazon shoppers who have elected to donate to a charity of their choice using smile.amazon.com, Amazon has donated over $105 MILLION DOLLARS to 501(c)(3) charitable organizations! Judging by the amount of Amazon packages at our tiny Harsen’s Island Post Office every day, your HISCFA could really benefit from the Smile Foundation and shoppers like you. Please consider setting this up on your account for all your future Amazon purchases.

Happy shopping!

Association Benefits:

There are many values the Association provides Harsen’s Island residents through our membership dues and volunteers. Many residents see our contributions to the island,  but may not know what  they are seeing is supported by your HISCFA membership dues, donations, and hard work by our volunteers and directors.

When arriving on the island, the Advertising Sign, equipped with a large digital marquee, and the well-manicured Browne’s Field, greet our residents and guests. Turning to the right we maintain  the Island Park ‘N’ Ride located near the stone yard; a parking area for residents who want to park and ride on the ferry across to the mainland. Turning to the left past Browne’s Field is the Water Station; a source of clean drinking water for those residents on the Island that do not have access to city water or for use on their boats. The  HISCFA  also maintains a seasonal water pump further down the main highway at the Bates Cut. The Delta News magazine is our annual report, which is full of stories that are of interest to our Islanders, and a showcase for our many advertisers and their services. These are tangible assets that are maintained by the membership dues and by our directors and volunteers.

The Association provides so much more to our community. Your dues provide monthly donations to both the Lions Club and Reader’s Cove on the Island. We have an  Outreach Committee for those Islanders in need, and provide scholarships to deserving high school seniors. Our Government Affairs Committee strives to keep our Island  residents updated on issues that will impact Island property owners. The Great Lakes Island Coalition was newly formed this year, and one of our directors attended the  introductory summit held on Beaver Island this past fall. The purpose of this exciting new group is an exchange of unique challenges faced by islands in the Great Lakes  and to share their possible solutions for the improvement of all island communities. We are keeping a close eye on what benefits this coalition will have for Harsen’s Island in the years to come.

The Association also provides some fun for our Islanders, starting the summer off with the Classic Car Show at Browne’s Field in July, followed by Field Day on the first Saturday in August, and ending with our fall party Bonfire and Pig Roast in September.
