NALMS Honors Your Contributions

NALMS Guidestar Badge

NALMS is a 501(c)(3) tax-exempt nonprofit organization. We strive to be good stewards of the fiscal gifts made by members, donors and partners like you. Please see the links below so you may feel sure of your gift.

Throughout its history, the North American Lake Management Society (NALMS) has been funded largely through a combination of membership dues, conference revenue, and grants from federal agencies. As federal grant funds decreased and the competition for those limited funds increased, programs and activities that had previously received grant funding are now reliant on the same funding sources as the rest of the organization’s general operations: membership dues, conference revenues, and donations.

In recent years, NALMS has put a greater focus on diversifying its income sources through non-governmental grants, exploring sponsorship opportunities for key programs, and developing a culture of giving within the organization. NALMS has also made a concerted effort to expand the visibility of the organization through increased social media and outreach activities.
