High Water Mark

What High Water Mark does

High Water Mark, LLC is a 100% Native American-woman owned environmental consulting firm headquartered in Bernalillo, New Mexico, founded in 2013 by Phoebe Suina. The firm delivers an integrated suite of professional services spanning water resources, watershed management, and emergency management: hydrologic studies, groundwater monitoring, surface water and stormwater regulatory compliance, watershed assessments and wetland delineation, Clean Water Act Section 401/404 permitting, GIS support, geomorphic surveying, construction management and oversight, FEMA grant assistance, hazard mitigation planning, community-based outreach, and, more recently, climate change adaptation. Originating in burn-area recovery and post-fire flood damage assessment in fire-impacted watersheds, the company has expanded into multi-stakeholder planning across local, state, federal, and tribal entities.

The customer base is concentrated among tribal communities (Pueblo of Nambe, Pueblo de Jemez, Pueblo de Cochiti, Santo Domingo Pueblo, San Felipe Pueblo, Pueblo San Ildefonso), municipalities (Village of Pecos, Village of Ruidoso, Harding County), the Pojoaque Valley Irrigation District, and federal agencies (Los Alamos National Laboratories) across New Mexico and the broader Southwest. High Water Mark operates a sales-led, project-based consulting model: proposal-driven engagements with direct client relationships, professional services fees tied to grant-funded and government contracts, and no publicly disclosed pricing. Notable client outcomes include helping communities secure over $60 million in flood-damage aid, assisting with $20+ million in grant/loan funding, winning $10M+ in infrastructure/renewable energy/environmental funding, and managing a portfolio of more than 40 projects totaling $50M+ in value.

Leadership combines deep regulatory expertise with cultural credibility. Founder Phoebe Suina has 20+ years of experience at FEMA, DOE, the U.S. Bureau of Reclamation, and Los Alamos National Laboratory, and holds graduate degrees from Dartmouth's Thayer School of Engineering. The firm is a NOAA Weather-Ready Nation Ambassador, holds SBA Women-Owned Small Business (WOSB) certification, and has earned media coverage from PBS New Mexico, Dartmouth Alumni Magazine, and the Albuquerque Journal for tribal environmental rights advocacy.
