Citation: Vogel, J.R., Brown, G.O., Daniel, J.A., Phillips, W.A., Garbrecht, J.D. 2000. Watershed management practices (1976-1999) for the water resources and erosion watersheds at the USDA-ARS Grazinglands Research Laboratory, El Reno, OK. Grazinglands Research Laboratory Research Publication. 75 p. Interpretive Summary: This report summarizes the historical tillage and grazing management practices at the Water Resources and Erosion (WRE) unit source watersheds at the Grazinglands Research Laboratory. The report provides a brief history of the WRE watersheds, describes the land use and management of each watershed from 1976 through 1999, provides tables of dates and types of management practices for each watershed, and lists publications related to the WRE watersheds. The WRE watersheds are a source of data for various research projects, and the historical tillage and grazing management data presented in this report are shared between research projects. The purpose of this report is to provide a summary of the available tillage and grazing management data to scientists, collaborators and those responsible for planning and management of the WRE watersheds.
Technical Abstract: The USDA-ARS Grazinglands Research Laboratory located west of El Reno, OK has been operating, maintaining, and monitoring eight 1.6 ha experimental unit-source watersheds since 1976. This includes four native grass and four winter-wheat watersheds. Each watershed is equipped with runoff weirs with stream gage recorders, runoff samplers, groundwater monitoring wells and soil moisture access tubes, as well as precipitation recording devices. Because of the vast and complete nature of the long-term hydrologic records of these watersheds, this report summarizes the management practices on these watersheds from 1976 until 1999 to allow expansion of future research. Source information used included yearly management logs and published papers. It is anticipated that this report will be a useful reference on the history of the management practices, and a tool to help formulate future research goals and objectives for the WRE watersheds.
