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 http://coloradoewp.com.
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.
Projects in the Colorado Risk MAP Program:
Big Thompson Discovery
El Paso County FIRM Updates
St. Vrain Risk MAP Project
Upper White Risk MAP Project
BTRRC Project Maps
Thanks to our former Assistant Watershed Coordinator Clara Moulton for these maps.
Info on fires located only on federal lands with no state support can be found at Rocky Mountain Area Coordination Center https://gacc.nifc.gov/rmcc/
US Geological Survey: Hazards Data Distribution System Viewer
http://gisdata.usgs.gov/website/eo/ This one takes some playing around with – zoom in, hover in the upper lefthand corner to see the various options. I’m not sure what it does for us, aside from earthquakes, but it’s a map.
Endangered and Threatened Species
Information for Conservation and Planning US Fish and Wildlife Service
“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.
Colorado’s Flood Decision Support System
Flood DSS Map Viewer
Review effective floodplain boundaries.
See real-time weather and streamflow conditions.
Access local and county data related to flooding.
Access data related to historical floods, hazards, weather modification, watershed restoration, and FEMA’s National Flood Insurance Program.
Colorado Flood Threat Portal Active from May 1 through September.
A daily assessment of flood potential around the state, issued at 11am each day from May through September.
Statewide 24-hr Precipitation Map
Daily Statewide Flood Threat Bulletin and Map
7-15 Day Flood Threat Outlook (updated Mondays and Thursdays)
Assess current snow conditions near weather modification locations.
Assess streamflow conditions near restoration project locations.
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.”

Larimer County Enterprise Map Portal Includes interactive flood map

The access point to information frequently used for transportation planning and project development. Information is provided on current and projected traffic volumes, state highway attributes, summary roadway statistics, demographics and geographic data.
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:
Colorado Department of Local Affairs (DOLA)
. There is quite a bit of information on the DOLA site, so be sure to click on the menu links.
FEMA, CWCB etc.
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.
Crisis Cleanup.org is a free-ware mapping application available to volunteer organizations that assist with disaster recovery. You can see where volunteer projects were logged in our area, but not a lot of info. The main thing is you should keep this tool in mind when working on coordinating volunteer projects.
Dept of Homeland Security Emergency Management map
This map is a particularly good pre-flood reference tool now that Google Maps shows post flood in the aerial views. To get a clean view (without Disaster Centers marked), go into Basemap and select “Imagery with Labels.” Click on “Details” and click off the Disaster Centers option. Now, you can move around and zoom in just like Google Maps.
