Project Maps

There are several interactive maps of the flood-affected areas on the Internet. Here are some links.
The CWCB has created a new website devoted to the Colorado Emergency Watershed Protection (EWP) Program available at
The website provides current information on the EWP Program for the public, as well as resources to assist watershed coordinators, local governments, landowners, and other interested parties with the implementation of watershed recovery projects.

Key features of the website:
– Interactive map of EWP watershed recovery projects with descriptions of each project.
– EWP Program requirements, timeline, guidance documents, and other resources

– Description and contact information for each watershed coalition

The website will be updated on a regular basis with program news, technical resources, and information on EWP projects.

“The Endangered Species Act (ESA) delivers remarkable successes. Looking back on the ESA’s 40-year history, we recognize that it has helped stabilize populations of species at risk, prevent the extinction of many others, and conserve the habitats upon which they depend. All Americans can take pride in the fact that, under the ESA, California condor, grizzly bear, Okaloosa darter, whooping crane, and black-footed ferret have all been brought back from the brink of extinction. We can also celebrate that many other species no longer need the ESA’s protection and have been removed from the list of endangered and threatened species, including the bald eagle—the very symbol of our nation’s strength.

The National Water and Climate Center (NWCC) recently released a new version of their interactive map. This release lets users view current climatic conditions, such as precipitation, snow water equivalent and streamflow volume. Here are just a few examples of what you can map:
Current Snow Water Equivalent as a Percent of Median
Water Year to Date Precipitation

The map also provides access to predefined reports and site pages. Simply click on a site to get station information, summary statistics and access to reports.

The WEPP Online GIS Watershed Interface, allows watershed-level erosion predictions on any PC with access to Google Maps. FS-WEPP is being continually refined, improved, and expanded upon to increase its usefulness, and to enable managers to run predictive watershed models for better land management decision-making and more desirable outcomes.”

The Windshield App allows you to go back in time. The 2013 photos appear to have been taken in spring of 2013.

CDOT Floods Map

This next CDOT map has before/after pictures of the 2013 Flood and Civil Air Patrol aerial photos taken in September 2013. Remember that the locations marked on the map are where the airplane was located when it took the picture, not the location of what is shown in the picture. You usually have to click on a lot of pictures to find the one of your property, but it’s most likely there somewhere. Once you click on the thumbnail to open it, you can click again to zoom in and use scroll bars on the sides of your open window to get around.

If you don’t see all the features immediately, use the zoom-in, zoom-out:

The Colorado Risk MAP program is a collaborative effort among the CWCB, FEMA, and local communities. Projects are cost-shared among FEMA, CWCB and local communities and mapping needs for each community is assessed early on during a discovery or scoping meeting. The project scope is determined after careful consideration of local community needs and available funding. CWCB mapping partners are responsible for the work performed as part of the Risk MAP projects.

You may view or download current effective FIRMs or DFIRMs and associated FIS reports or order printed paper copies of current effective FIRMs or DFIRMs and FIS reports from the FEMA Map Service Center Website. You may also contact the Map Service Center by telephone, toll free, at 1-800-358-9616.
