Overview

Mission

The harsens island/st. Clair flats historical societys mission is to collect, protect, preserve and share with the public the unique historical artifacts and information that represents the diverse cultural composition of the people that occupied the area of the st. Clair river delta that is harsens island and the st. Clair flats.

What it reported doing in 2025

The harsens island st. Clair flats historical society opened the museum over the memorial day weekend again in 2025, with many visitors and special groups visiting throughout the summer. We maintained our normal week-end hours may-september. The speaker series again was well attended, with speakers discussing local shipwrecks, and one of our board members shared her three fires presentation (history of neighboring walpole island) designed for her 3rd graders but was well attended by many who were young at heart. The museum opened for 3 annual events and fundraisers after september, which are always popular - the fall pie sale, an edmund fitzgerald remembrance event, and the christmas cookie walk. Our major event was a murder mystery party held in june at the museum. The museum was turned into a 1928 speak-easy, where all the passengers on the tashmoo had to disembark after a body was found on the ship. Attendees had roles to play as they enjoyed appetizers and craft cocktails of the time, and solved the mystery. Everyone dressed their part and the evening was truly special.

Operating model

Revenue model
Earned-program. 99% of the money available for current operations came from fees and other program revenue.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Expenses are high relative to revenue and revenue has declined or grown slowly.
