Gratiot Lake Conservancy is a private corporation based in OAK BROOK, IL. The foundation received its IRS ruling in 1998. The principal officer is Louis L Lizzadro. It holds total assets of $13.1M. Annual income is reported at $96K. Total assets have grown from $2.5M in 2011 to $13.1M in 2024. Tax records are available from 2020 to 2024. According to available records, Gratiot Lake Conservancy has made 2 grants totaling $300, with a median grant of $150. Annual giving has grown from $100 in 2022 to $200 in 2023. Individual grants have ranged from $100 to $200, with an average award of $150. The foundation has supported 2 unique organizations. Grants have been distributed to organizations in Michigan and Wisconsin. Contributions to this foundation are tax-deductible.
Gratiot Lake Conservancy (GLC) is an IRS-classified private operating foundation (is_operating = true), holding $13.08M in total assets as of FY2024. That classification is the single most important fact for any prospective applicant: it means GLC exists primarily to run its own direct charitable programs — managing the 976-acre Gratiot Lake Preserve (510+ acres, 14,000 feet of shoreline) and the 466-acre Bammert Farm in Keweenaw County, Michigan — rather than to fund outside nonprofits. External cash grants on record are essentially token: only two recipients appear in the grants data, Eagle Harbor Township ($200, general purpose) and Wild Ones Keweenaw Chapter ($100, general purpose), both hyper-local partners tied directly to the preserve's home township and regional native-plant community.
GLC's own IRS filing spells out its actual "application" process, and it is not a funding request: the application_instructions field requires only "a letter describing activities to be conducted at the Conservancy's property," restricted to "studies and education in ecology and conservancy." There is no LOI-to-full-proposal pipeline, no board cycle publicized, no site-visit protocol, and no RFP — this is a foundation set up to steward one specific landscape, not to run a competitive grants program.
First-time applicants should recalibrate expectations accordingly. GLC is not a fit for general operating support, capital campaigns, or any program that isn't physically rooted in the Gratiot Lake watershed or Bammert Farm. The realistic path in mirrors what's already funded: Zach Merrill's multi-year dendrochronology research (undergraduate involvement, interpretive signage), the Alliance for the Great Lakes' Adopt-a-Beach shoreline cleanup, and KISMA's invasive-species removal crews. All are hands-on, site-based, and delivered by organizations already active in Michigan's Upper Peninsula. GLC is administered on paper from Oak Brook, IL (contact Louis L. Lizzadro), but its working office and program authority sit in Mohawk, MI — reach the director there, not the Illinois address.
GLC's grantee data shows only two external cash grants on record: $200 to Eagle Harbor Township and $100 to Wild Ones Keweenaw Chapter — an average/median of $150 and a full range of $100-$200. Combined, that is $300 in total external giving across the available snapshot, 100% of it staying within Michigan's Keweenaw Peninsula (Eagle Harbor Township) and to a chapter organization whose work is likewise local to the Keweenaw region.
That trivial external-grants figure sits in sharp contrast to the 990's broader "total_giving" line, which captures GLC's own direct charitable program spending (land management, research, education) rather than third-party grants: $50,531 (FY2019), $33,470 (FY2020), $22,230 (FY2021), $24,006 (FY2022), and $28,557 (FY2023) — a consistent $22K-$50K/year band over the last five reported years, with essentially none of it flowing to outside grantees.
Assets have grown from roughly $2.5M (FY2012-2014) to $7.8M in FY2015 — driven by a one-time $5.28M contribution spike that year, likely a major gift or land-related transfer — and then climbed more gradually to $12.7M-$13.1M across FY2019-2024, mostly on investment income of $10,000-$15,000/year plus modest annual contributions ($50,000-$60,000 in FY2020-2023). FY2024 total revenue jumped sharply to $940,005 against a prior-year range of $65,000-$80,000; total_giving and grants_paid for FY2024 are both unreported (null) pending fuller 990 processing, so it isn't yet possible to say whether that inflow will translate into any change in external grantmaking.
By program area, 100% of recorded external grant dollars and 100% of programmatic activity fall under environment/conservation-education (NTEE C30, Natural Resources Conservation & Protection), consistent with GLC's singular focus on the Gratiot Lake watershed and its two owned properties. There is no evidence in either the financial history or the 990 program narrative of diversification into other causes, states, or grantee types.
GLC sits among a cluster of similarly sized Environment-category private foundations, most structured — like GLC — around stewardship of a specific property rather than broad competitive grantmaking:
| Foundation | Assets | Annual Giving | Primary Focus | Application |
|---|---|---|---|---|
| Gratiot Lake Conservancy (MI/IL) | $13.08M | ~$150-$300 external grants/yr ($22K-$50K total program spend) | Lake/watershed conservation, ecology education | Letter describing on-site activities; no portal |
| Realty Gift Fund (NM) | $13.11M | Not publicly reported | Environment | Not publicly reported |
| Visa Vel Foundation (TX) | $13.71M | Not publicly reported | Environment | Not publicly reported |
| Yakona Nature Preserve (OR) | $12.48M | Not publicly reported | Environment | Not publicly reported |
| Turner Farm Preservation Foundation (OH) | $13.76M | Not publicly reported | Environment | Not publicly reported |
| Gordon Rausser Foundation (CA) | $13.89M | Not publicly reported | Environment | Not publicly reported |
All six foundations cluster tightly in the $12.5M-$13.9M asset band, and none has a public website surfacing a conventional application portal or published giving figures — a pattern typical of single-property land trusts and nature-preserve foundations, which tend to spend the bulk of their resources on direct stewardship of the land they own rather than on third-party grants. For a grant seeker, this peer set is a signal, not an opportunity list: these are largely self-directed operating foundations, and none should be expected to behave like a program-area funder accepting unsolicited applications from unaffiliated organizations.
GLC's public-facing news output is sparse and infrequent. The two most recent items on its own news page are operational rather than programmatic: a July 8, 2026 update that the Noblet Lane access route to the Noblet Field Station has been cleared and reopened to higher-clearance vehicles, and a November 20, 2025 notice that the Fall 2025 "Water's Edge" member newsletter had been released (its contents were not summarized on the news index itself).
The more substantive recent activity comes from GLC's FY2024 Form 990-PF program narrative. Four items stand out: continuity in Keweenaw Community Forest Company's (KCFC) management of GLC land — opening roads and trails, installing the dock, and maintaining the Noblet Field; a three-year dendrochronology research project spun off from Zach Merrill's work, now producing interpretive signage about historically significant trees around Gratiot Lake, built with undergraduate students and the KCFC program director; a September shoreline cleanup in partnership with the Alliance for the Great Lakes' Adopt-a-Beach program, removing over 20 pounds of trash; and a KISMA (Keweenaw Invasive Species Management Area) weed crew removing invasive thistle from the preserve and access road, plus a boat-wash demonstration for aquatic invasive species in late July.
No leadership changes, new program launches, or named large grants were found in available web sources. FY2024 total revenue rose sharply to $940,005 (versus $65,000-$80,000 in most prior years), but the corresponding giving and grants-paid figures for that year are not yet reported, so it's not possible to say what — if anything — that inflow funded.
GLC does not run a conventional grant program, so generic grant-writing advice does not apply here — the tips below are specific to what actually appears to move this funder. First, treat any approach as a site-use or partnership request, not a funding application: the 990 lists the only formal requirement as "a letter describing activities to be conducted at the Conservancy's property," restricted to "studies and education in ecology and conservancy." A proposal for anything not physically tied to Gratiot Lake Preserve, Bammert Farm, or the Noblet Field Station is off-thesis by definition.
Second, use the funded-activity pattern as your template. Every program GLC has actually supported in its most recent filing year is hands-on and site-based: a multi-year tree-ring (dendrochronology) research project that produced public interpretive signage, a shoreline litter cleanup run jointly with the Alliance for the Great Lakes' established Adopt-a-Beach program, and invasive-species removal delivered by KISMA, a standing regional partnership. Proposals modeled on these — specific, physical, deliverable-driven, and executed with (or by) an organization already working in the Keweenaw Peninsula — have the clearest precedent.
Third, go direct and go local. Contact the director at director@gratiotlakeconservancy.org or (906) 337-5476, the Mohawk, MI office — not the Oak Brook, IL address on the 990, which functions as a registered/accounting address rather than a working office. Given the entire recorded external cash-grant history is two payments of $100 and $200 to hyper-local recipients (Eagle Harbor Township, Wild Ones Keweenaw Chapter), do not anchor a request to a specific dollar figure; the realistic ask is in-kind support, property access, or a modest reimbursement tied to a defined activity, not a five- or six-figure program grant.
Fourth, avoid the most common mistake for this funder: treating it like a standard environmental foundation with a competitive RFP cycle. There is no public portal, no published deadline, and no listed board review calendar. Cold, generic LOIs unconnected to the Gratiot Lake watershed are very unlikely to get a response — regional credibility (Michigan Tech, KISMA, Alliance for the Great Lakes-type affiliations) appears to be the actual door-opener, not proposal polish.

Dendrochronology research - a three year spinoff of zach merrill's research at gratiot lake conservancy. This involves engaging undergrad students kcfc the program director and zach merrill in the design and installation of interpretive signage. The signs provide educational content about historically significant trees and various tree species around gratiot lake.
Clearner beach - gratiot lake conservancy hosted a september shoreline clean-up of gratiot lake in partnership with the alliance for the great lakes adopt-a-beach program. Volunteers picked up over 20 pounds of trash from the shoreline.
The keweenaw invasive species area kisma weed crew removed invasive thistle from the gratiot lake conservancy preserve and access road. Kisma also offered a boat wash demo to remove invasive aquatic species at the gratiot lake public access in late july.
