NHDPlus
NHDPlus is a detailed digital map system that combines river and stream data with geographic information to help people understand water flow, water quality, and related environmental features. It integrates data on river networks, watershed boundaries, and flow paths, allowing for better planning, management, and analysis of water resources. Used by scientists, engineers, and policymakers, NHDPlus enables accurate modeling of water movement and helps address issues like flooding, pollution, and habitat conservation, making complex hydrological information accessible for informed decision-making.
