Programs
Program: MUSEUM/DISPLAYS LMHS operates museums in Lake Minnetonka's three population centers: Excelsior, Mound, and Wayzata. Staffed by volunteers docents, Excelsior and Wayzata museums are seasonal museums open in the summer; Mound is open year-round. These museums enable the public to interact directly with the history of Lake Minnetonka through accessing each museum's exhibits and displays. In addition to its museums, LHMS operates a Garden Railroad at the Wayzata museum and is currently working to return the Streetcar Boat MINNEHAHA(listed in the National Register of Historic Places) to active operation on the lake. Through these experiential activities, young and old can learn and experience life as it was in the late 1800s and early 1900s. Attendance at the museums varies by location and weather but ranges between 50-200 per weekend. MINNEHAHA ridership, when operational, averages 10,000 per season.

Open to the public, these programs provide a deeper dive into specific topics beyond what each museum's interpretive displays allow. Presentations rotate across the three population centers and are customized to each location to reflect each community's identity/history.. Presentations are provided free to the public, except during the summer months when they are conducted aboard a chartered excursion vessel.

The organization over time
Each line starts at 100 in 2024, so what you read is the shape rather than the size: 150 means half as much again as 2024, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $549k to $472k (−14%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2024 18%. Grants only. Government contracts and fees sit inside program revenue.
71% of LAKE MINNETONKA HISTORICAL SOCIETY’s revenue is contributions — more donation-reliant than the typical peer (64% for the typical peer).

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
1 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 5% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of LAKE MINNETONKA HISTORICAL SOCIETY’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

the vertical line marks half of all grant income — 1 funder to its left
86% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund LAKE MINNETONKA HISTORICAL SOCIETY.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

Funder states come from each funder’s own filing. $6k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
