FOR URBAN WATERSHEDS

These links were compiled by Dr. Ron Stewart as part of a group project for the GMU course entitled "Forested Watersheds."

Maps, Map-Based Information, and Data Sets

     The U.S. Environmental Protection Agency: EPA maintains a number of useful watershed related websites.  Surf Your Watershed allows you to locate your watershed and to obtain specific information about watershed condition from EPA’s database.  This site also links to a Watershed Atlas that contains a geo-spatial display and analyses of information important for watershed restoration and protection.  This includes an Enviromapper for Watersheds that displays various indices of watershed indicators selected by the user.  Finally, the EPA Office of Water has a useful home page with various links to publications, laws and regulations, training, and other environmentally related websites.

    U.S. Geological Survey:  The USGS maintains a wealth of map-based information on all U.S. watersheds.  The National Mapping Information page contains information on obtaining electronic geospatial data files, aerial photos, and maps.  The GIS Data for Water Resources is a particularly useful site that allows you to find and access spatial data related to water resources and the National Water Information System.  The National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, springs and wells.  USGS also maintains hydrologic unit maps and a site containing information on Difficult Run.  The Geographic Names Information System (GNIS), developed by the USGS in cooperation with the U.S. Board on Geographic Names (BGN), contains information about almost 2 million physical and cultural geographic features in the United States.  The National Atlas of the United States updates a large bound collection of paper maps that was published in 1970.  It delivers easy to use, map-like views of America's natural and sociocultural landscapes. Unlike the previous Atlas, this version is largely digital.

Manuals, Handbooks and Educational Resources

Many of the government and non-government organizations listed here have educational materials available.  Some have information for use by children.  In addition, several universities have training and teaching materials available, sometimes through their extension activities.

    Purdue University: As an example, Purdue University has a “Know Your Watershed” website where you can download videos that define a watershed and show how watersheds are impacted.  This site also links to a number of watershed guides: building local partnerships, getting to know your watershed, leading and communicating, managing conflict, putting together a watershed plan, reflecting on lakes, wetlands: a key link in watershed management, and ground and surface water: understanding the interaction.

     The Interagency Stream Corridor Restoration Working Group: Fifteen federal agencies combined their experience, skills and technology as the ISCRWG to produce “Stream Corridor Restoration: Principles, Processes, and Practices.

    Cooperative State Research, Education, and Extension Service: The USDA Cooperative State Research, Education, and Extension Service (CREES) National Program in Natural Resources and responds to a broad spectrum of natural resource and environmental issues: air quality; animal waste management; biodiversity; climate changes; conflict resolution; ecosystem management; fish and wildlife management; forestry; geographic information systems; housing and indoor air quality; land-use planning; public issues education; remote sensing for forest mapping, soil studies, range management; soil science; solid waste management; water quality; watershed science; and wood products.

Models and Software

     U.S. State and Local Gateway (U.S. EPA): EPA maintains a website, “Environment/Energy Tools,” that includes links to the Center for Environmental Information and Statistics (CEIS), community based environmental protection, EPA databases and software, envirofacts, environmental software, environmental planning for small communities, pollution prevention tools for homeowners and renters, and others.

    American Forests: American Forests developed CITYgreen , a GIS-based software tool that helps people understand the value of trees to the local environment.
Planners and natural resources professionals use the program to test landscape ordinances, evaluate site plans and model development scenarios that capture the benefits of trees. The software conducts complex statistical analyses of ecosystem services and creates easy-to-understand maps and reports. CITYgreen calculates dollar benefits based on your specific site conditions. CITYgreen analyzes: stormwater runoff, air quality, summer energy savings, carbon storage and avoidance, and tree growth.
· CITYgreen website

    Natural Resources Conservation Service: The USDA Natural Resources Conservation Service (NRCS) has designed a runoff model, Technical Release 55 (TR-55).  The model presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs.  These procedures are applicable in small watersheds, especially urbanizing watersheds, in the United States. Limits: NRCS type distributions, 24-hour duration rainfall, 10 subwatersheds, minimum 0.1 hour and maximum 10-hour time of concentration.  The model can be downloaded free of charge.

    Center for Watershed Protection: Founded in 1992, the CWP works with local, state, and federal governmental agencies, environmental consulting firms, watershed organizations, and the general public to provide objective and scientifically sound information on effective techniques to protect and restore urban watersheds.   They have CD-ROM presentations designed to provide community leaders, watershed managers, educators and activists with materials to craft their own watershed protection seminars. The Center also acts as a technical resource for local and state
governments around the country to develop more effective urban stormwater and watershed protection programs. The Center publishes a periodic journal entitled Watershed Protection Techniques, which provides reliable and accurate summaries of the latest tools for protecting watersheds across North America. Techniques is designed to link watershed practitioners together and provide a forum in which to exchange research, ideas, and experience in the field.   Their home page has links to watershed planning, land conservation, aquatic buffers, better site design, erosion control, stormwater BMPs, non-stormwater discharges, and watershed stewardship (under “Protecting a Watershed”), and model ordinances.  Their “Protecting a Watershed” link is particularly useful.

    American Forests:  American Forests is the nation's oldest nonprofit citizen conservation organization, founded in 1875 by citizens concerned about waste and abuse of the nation's forests. Their mission today remains helping people improve the environment with trees and forests. They work to ensure a sustainable future for our nation's forests - both urban and rural - through national and international tree planting, forest policy, urban forestry, and popular programs, such as Global ReLeaf.  Through their Global ReLeaf program, they have planted more than 15 million trees in 500+ forest ecosystem restoration projects and urban and community forest projects. Their home page links to an extensive information base on trees, cities and sprawl; and to a watershed planning tool called CITYGreen 4.0.
