2 other organizations in the IRS Business Master File list the same street address. matched by us

This address is a suite or unit (STE 100). Organizations that share one are often clients of the same office-services firm, accountant or registered agent rather than related to each other.

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2024

Mission

The Great Lakes Fishery Commission is an international treaty organization established in 1955 by the Canadian/U.S. Convention on Great Lakes Fisheries. The commission coordinates fisheries research, controls the invasive sea lamprey, and facilitates cooperative fishery management among the state, provincial, tribal, and federal agencies.

Activities or mission (Part I)

The Great Lakes Fishery Commission is an international treaty organization established to coordinate fisheries research, control invasive sea lampreys, and facilitate cooperative fishery management among the state, provincial, tribal, and federal agencies.

  • Research Program - Research contracts, workshops, and task forces were elements of a coordinated program of the Great Lakes Research Program designed to recommend to the U.S. and Canadian federal governments the measures needed to permit maximum sustained productivity of fish stocks.

    Expenses $16,146,253

  • Sea Lamprey Management Program - Great Lakes Fishery Commission contracts annually with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, and Fisheries and Oceans Canada to conduct a program that eradicates or minimizes sea lamprey populations in the Great Lakes. This is a current and long-term goal. Lampricides are chemicals used as the major means of controlling sea lamprey in the commission's ongoing program of sea lamprey management in the Great Lakes. These chemicals are purchased annually.

    Expenses $21,700,728

  • Infrastructure - The Great Lakes Fishery Commission relies on physical infrastructure in its programs including 1) sea lamprey barriers, 2) sea lamprey traps, 3) biological stations, 4) workspace, and 5) researcher accommodations. Sea lamprey barriers are extremely cost-effective and provide an assumed 50-year life span. Barriers are used as a means of controlling sea lamprey by blocking streams and rivers in which they migrate to spawn. These are current and long-term projects.

    Expenses $9,050,031

  • Professional development, memberships, sponsorships, along with Lake Champlain and CARES Act II expenditures. Lake Champlain is explained on Schedule O. All other functional expenses related to running programs.

    Expenses $17,745,279

As filed on the 2024 return. The filer continues this part on Schedule O, which is not shown here.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility SOUNK.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
