The Agricultural Conservation Planning Framework (ACPF): A Watershed Planning Tool


About the ACPF
Facilitating Conservation Planning in Agricultural Watersheds

The ACPF watershed planning toolbox is intended to leverage modern data sources and help local farming communities better address soil and water conservation needs. We believe water quality challenges can be better met by improving the quality of information used to identify conservation options in watersheds and on farms. High-resolution geo-spatial datasets that can improve the information base available for conservation planning have recently become available. The Agricultural Conservation Planning Framework (ACPF) toolbox can be used within the ArcGIS® (Ver. 10.2 – 10.5) environment to analyze soils, land use, and high-resolution topographic data to identify a broad range of opportunities to install conservation practices in fields and in watersheds. These opportunities can then inform of a non-prescriptive approach to encourage farmers and landowners to become engaged in local watershed improvement.

The ACPF Toolbox Contains Tools To:
  • Process (or “hydro-condition”) a watershed’s high-resolution topographic data for terrain analyses
  • Determine which fields within a watershed are most prone to contribute runoff to streams
  • Identify where field-scale and edge-of-field practices could be installed in your watershed, including:
    • Controlled Drainage (drainage water management)
    • Surface Intake Filters or Restored Wetlands for topographic depressions
    • Grassed Waterways
    • Contour Buffer Strips
    • Water and Sediment Control Basins
    • Nutrient Removal Wetlands
    • Edge-of-field Bioreactors
  • Map opportunities for riparian management:
    • Prioritize for runoff interception and to address bank erosion
    • Opportunities for removal of dissolved nutrients and floodplain reconnection
    • Saturated Riparian Buffers
User options are included in every tool to allow flexibility in matching practice-siting criteria to each local setting.


Where Has the ACPF Been Used?

This map shows watersheds where users have reported using the ACPF. Click on a watershed to learn who did the work. Watersheds can be submitted to this map by completing this form. If you have a large number of watersheds to submit, email to get a spreadsheet form.

Land Use and Soils Data: DOWNLOAD

Recent land use (through 2016), field boundary, and soil survey information for individual HUC12 watersheds in Iowa, Illinois, southern Minnesota, eastern Kansas, and portions of Nebraska, Missouri, and Wisconsin can be downloaded.

Via this ACPF land use viewer web page, users may navigate to individual HUC12 watersheds, view land-use maps, and download land use and soils data that can be directly used as input data for the ACPF toolbox. Before developing information on conservation priorities and opportunities using the ACPF toolbox, users will need to obtain elevation data for their watershed.

Elevation Data: DOWNLOAD

The ACPF Development Team at the USDA/ARS National Laboratory for Agriculture and the Environment, in cooperation with the Iowa State University GIS Facility (ISUGISF) are pleased to announce web access to state-wide, high-resolution elevation data for Iowa. These data are being made available in support of the Agricultural Conservation Planning Framework (ACPF) and other GIS applications. The new release and accompanying information is available on the ACPF DEM page, on the ISUGISF web. The ISUGISF has created an ArcGIS Server application to download 2-meter DEM by HUC12 watershed for the state of Iowa.

Support and Training
Training Videos:

The ACPF ArcGIS Training videos are a series of 26 lessons explaining how to setup, use, and interpret all the tools in the ACPF toolbox. This is essential training for users who have not attended a hands-on workshop or who want to review modules.

The videos are designed for people with intermediate ArcGIS skills, including importing and managing files and layers, and processing raster data such as for terrain analyses or hydrological modeling of DEMs. They assume the viewer is comfortable navigating toolboxes, using tool dialogs, manipulating map characteristics, moving around tables, and joining tables, etc.

The videos build on each other, so work through them in sequence from Lecture 1 to Lecture 26. As you watch, have the User Guide available and ArcGIS open so you can follow along. Allow two full days of watching the videos and practicing to become well-trained in using the ACPF.

ACPF Forum:

The ACPF Forum is an online group for discussing technical issues related to using the ACPF tools. Anyone can view the discussions Here. To participate, first join the group by sending an email to

Press Releases:

September 2015, AgResearch Magazine: Toolset Identifies Water Conservation Options
The ACPF was developed at the National Laboratory for Agriculture and the Environment (NLAE), of the USDA-Agricultural Research Service. The development team was led by Mark Tomer and NLAE is located in Ames Iowa.

Early versions of the ACPF toolbox were developed under a Conservation Innovation Grant (CIG) awarded by USDA-Natural Resources Conservation Service to the Environmental Defense Fund; Eileen McLellan was the project coordinator.
