1. Key Non-Governmental Organizations (NGOs)

Lake Chapala Birders: they run birding outings and report sightings in the Guadalajara Reporter. It’s an easy entry point for this crowd.

Lake Chapala Garden Club: a good fit for native plants

The Lake Chapala Society: not an environmental group, but it’s the main hub for expat

Amigos del Lago: the best-known group working on the lake’s health. Their listing gives amigosdelago.org and info@amigosdelago.org.

Ecología de Ribera Chapala: the nonprofit that runs the Ajijic Recycling Center. It reinvests its profits in the community.

Lakeside Wildlife Rescue & Rehabilitation: cares for injured wild animals.

Instituto Corazón de la Tierra

What they do: This is currently one of the most prominent and active scientific/environmental NGOs working on the lake. They run the Reforesta Chapala program, aiming to plant thousands of native trees in the surrounding sierras to prevent soil erosion and improve the lake’s water basin.

Focus Areas: They actively coordinate with local farmers and ranchers to promote regenerative agriculture and reduce agrochemical pollution runoff into the lake. They also manage the Chapala, Un Lago Vivo educational platform.

Sociedad Amigos del Lago de Chapala A.C.

What they do: While their web footprint has experienced changes, this historic local association remains integrated into international networks like the Global Nature Fund's Living Lakes Network to keep a spotlight on Chapala's status as a threatened global wetland. They focus on local water stewardship and community awareness.

2. Grassroots Coalitions & Activist Collectives

Lakeside Citizen Coalitions (Defensa del Lago)

What they do: In response to regional water politics—such as the state's engineering decisions regarding the Chapala-Guadalajara aqueduct—local activists have formed powerful, highly active legal and protest collectives.

Current Actions: These groups organize community marches for clean water and file federal injunctions to enforce environmental transparency laws. They frequently collaborate with researchers at the Universidad de Guadalajara (CUChapala) to hold public forums and build citizen-led regional action plans.

3. Inter-Municipal & Regional Agencies

AIPROMADES (Asociación Intermunicipal para la Protección del Medio Ambiente y Desarrollo Sustentable de la Región Chapala)

What they do: This is a formal, inter-municipal government association representing 16 municipalities surrounding the lake. They coordinate public policy on environmental conservation.

Focus Areas: If you are looking for structural volunteerism or technical projects, they manage large-scale initiatives dealing with forest fire prevention, solid waste management, combating invasive aquatic species (like water hyacinth), and managing territory conservation.

4.  Financial Giving (Tax-Deductible & Local Direct)

Adopt-a-Tree Program: You can directly fund the reforestation of Chapala's degraded ecosystems through the Instituto Corazón de la Tierra Facebook Page. Donors can fund native plantings via direct bank transfer (Santander, CLABE: 0143 2065 5007 7523 59, Memo: Reforesta Chapala). [1]

Foundation for Lake Chapala Charities: If you are a U.S. taxpayer seeking a tax deduction while funding regional grassroot efforts, this foundation acts as a vetted fiscal sponsor. They distribute roughly 97% of processed funds directly into local Lakeside charity programs. [1]

5. Citizen Activism & Legal Defense

"Salvemos Chapala" Collective: Public mobilization has sharply increased in response to local water quality issues and infrastructure threats like the proposed third aqueduct. The regional movement spearheaded recent megamarches in Guadalajara protesting for clean water access.

How to join: Activists actively request community help to spread environmental data, amplify calls-to-action, or support localized legal defenses. You can track their ongoing assembly points and digital actions by following the Salvemos Chapala account on Instagram or connecting via Facebook with local organizer Diego Medeles.

AIPROMADES: As an inter-municipal governance agency, they host public consultations, local forums, and workshops designed to involve towns and ejidos in establishing official Hydrological Protection Areas. You can drop into their local headquarters at Calle Las Redes No. 129, Chapala (Open Mon–Fri, 9:00 AM – 4:00 PM) to ask about upcoming citizen environmental forums.
