Time-lapse Photographs of Edge of Field site near Findlay, OH 2017–2020

This data release contains time-stamped photographs collected by U.S. Geological Survey (USGS) cameras deployed at an agricultural edge-of-field study site in the Eagle Creek watershed near Findlay, Ohio. The photographs were captured as part of a long-term (2012–20) investigation conducted by the USGS in cooperation with the Great Lakes Restoration Initiative and the U.S. Department of Agriculture Natural Resources Conservation Service to evaluate the effectiveness of conservation practices—including cover crops and variable rate technology—in reducing sediment and nutrient losses from agricultural fields. The camera images provided independent documentation of field management activities throughout the study. Photographs were used to corroborate the dates and times of producer actions such as planting, harvesting, tillage, fertilizer application, and aerial seeding of winter wheat. This verification supported the development of a complete time line of management practices, which was necessary to correctly interpret changes in runoff volume and water-quality responses measured at paired surface-runoff and subsurface-tile monitoring sites.
