"Are you interested in getting more agricultural conservation practices on the ground to help protect sources of drinking water? If you’re working at the state level, a natural ally is the Natural Resources Conservation Service (NRCS) State Conservationist’s office (part of the U.S. Department of Agriculture).

This toolkit, developed as a result of extensive collaboration between members of the Source Water Collaborative and the NRCS, offers a step-by-step approach."

This is a web-based tool to help producers easily calculate the quality of water flowing off their fields. Producers input variables about their field, such as slope, soil characteristics, nutrient and pest management, tillage practices, and, finally, conservation practices. Then WQIag takes the complex scientific information of these variables and synthesizes them into a single number. User will need to download Microsoft Silverlight to view the content.

How's My Waterway was designed to provide the general public with information about the condition of their local waters based on data that states, federal, tribal, local agencies and others have provided to EPA. Water quality information is displayed on 3 scales in How’s My Waterway; community, state and national.

"The Nonpoint Source (NPS) Outreach Toolbox is intended for use by state and local agencies and other organizations interested in educating the public on nonpoint source pollution or stormwater runoff. The Toolbox contains a variety of resources to help develop an effective and targeted outreach campaign."

"EPA’s National Stormwater Calculator is a desktop application that estimates the annual amount of rainwater and frequency of runoff from a specific site anywhere in the United States. Estimates are based on local soil conditions, land cover, and historic rainfall records."

CAST "is a web-based nitrogen, phosphorus and sediment load estimator tool that streamlines environmental planning. Users specify the Best Management Practices (BMPs) and their location. CAST builds the scenario and provides estimates of nitrogen, phosphorus, and sediment load reductions."

"i-Tree Hydro is a stand alone application designed to simulate the effects of changes in tree and impervious cover characteristics within a defined watershed on stream flow and water quality. It was designed specifically to handle urban vegetation effects so urban natural resource managers and urban planners can quantify the impacts of changes in tree and impervious cover on local hydrology to aid in management and planning decisions. The Hydro+ environmental model suite – called UnifiedHydro in reference to its C++ codebase – includes the models i-Tree Hydro, i-Tree Cool Air, and in the future potentially other models developed by the iTree-ESF collaborative."
