	The eel project involves teachers and students in studying how watershed characteristics on regional scales (for example, human development, removal of downstream dams) and local scales (water chemistry, stream size, stream habitat, culverts and other obstructions) affect the population density and distribution of eels of different sizes and ages. Work by the students and teachers provide National Park Service (NPS), state agencies, and researchers with data that can support resource management and new research.</p>
