A cocktail of land-based sources of pollution threatens coral reef ecosystems, and addressing these has become a key management and policy challenge in the State of Hawaii, other US territories, and globally. In West Maui, Hawai'i, nearly one quarter of all living corals were lost between 1995 and 2008. Onsite disposal systems (OSDS) for sewage leak contaminants into drinking water sources and nearshore waters. In recognition of this risk, the Hawaii State Department of Health (DOH) is prioritizing areas for cesspool upgrades. Independently, we applied a decision analysis process to identify priority areas to address sewage pollution from OSDS in West Maui, with the objective of reducing nearshore coral reef exposure...

Episodic runoff carries suspended sediment to the nearshore, where it blocks light used for photosynthesis, smothers corals, inhibits coral recruitment, and triggers increases in macroalgae. Even small rainfalls create visible plumes over a few hours. Sediment affects coastal user enjoyment by deteriorating both ecosystem quality and visibility. Sources of erosion include unimproved roads, fallow and active agricultural fields, disturbed forests, local development, and streambanks. In this project, USGS used mapping, field experiments and monitoring, and analysis of recent (July 19–20, 2014) and historic rainfall to estimate sources of land-based pollution for watersheds in West Maui, Hawaii. USGS constructed an...

Episodic runoff carries suspended sediment to the nearshore environment, where it blocks light used for photosynthesis, smothers corals, inhibits coral recruitment, and triggers increases in macroalgae. Even small rainfalls create visible plumes over a few hours. Sediment affects coastal user enjoyment by deteriorating both ecosystem quality and visibility. Sources of erosion include unimproved roads, fallow and active agricultural fields, disturbed forests, local development, and streambanks. This is the primary output dataset from this project, which mapped bank erosion hotspots, constructed a reconnaissance sediment budget for the West Maui watersheds, and constructed a calibrated decision-support model capable...
