CWCB–2019 Flood Season is Approaching

On May 16, 2019 the Colorado Department of Natural Resources / Colorado Water Conservation Board released an executive summary  entitled: 2019 Flood Season is Approaching.  While the South Platte River basin is not the State’s greatest flooding concern this year, temperature and precipitation outlooks suggest that streamflows from snowmelt runoff in the Denver/Boulder region will be much higher than last year. For information about the current snowpack conditions, visit https://alert5.udfcd.org/nrcs-snotel/.

News Release

DENVER, April 15, 2019 – Today the Flood Control District is launching its 41st annual flood prediction and notification service. This long-running program serves the 7-county Denver region by working in close partnership with the National Weather Service to alert local authorities of developing flood threats.

A large network of rain and stream gauges with over 200 stations  allows continuous monitoring of threatening weather and flood conditions. Alerts are sent automatically when alarm thresholds are exceeded. Twitter users can receive these notifications from the ALERT System when heavy rainfall is occurring in the region.

Forecasters at Skyview Weather provide essential meteorological support that includes calling 911 communication centers when flooding is imminent. Critical information is then relayed to the appropriate response agencies.

As we enter the 2019 flooding season, the Flood Control District urges that everyone to: 1) heed flood warnings by taking protective actions recommended by the NWS, local news stations and public safety officials; 2) avoid trail use near streams during heavy downpours; 3) not drive into floodwaters or enter flooded areas on foot; 4) be aware of flood risks near your home, school and workplace; and 5) consider purchasing flood insurance. Stay flood safe!

About the Flood Control District:
The Urban Drainage and Flood Control District was established by the Colorado legislature in 1969 to protect people, property and the environment by working regionally with local governments to address drainage and flood hazards. This is accomplished through a combination of preservation, mitigation and education activities. The District serves a population of approximately 3 million and covers a 1,600 plus square-mile area that includes Denver, parts of the six surrounding counties, and 32 incorporated cities and towns.

Mission

Paramount to UDFCD’s mission is the personal health, safety and welfare of all people that live and work in the Denver metropolitan area and of many visitors that come to enjoy this incredible gateway to the Rocky Mountains.

UDFCD’s flood warning services are primarily oriented toward individual flood safety that requires protective actions to be taken on the part of those individuals to achieve the desired outcome–no lives lost.  For flood warnings to be effective, people must first be aware of the flood risks they are living with and take appropriate steps to protect themselves when floods threaten.

Communities play a major role in educating residents about flood dangers and how to stay safe during floods.  Actions taken before a flood like purchasing flood insurance, implementing measures to reduce risks to property, having a home or business emergency plan, practicing the plan, keeping emergency supplies on hand including a ‘Go Pack’, and evacuating when advised by local authorities will help assure that you and your loved ones are safe when the worst happens.

UDFCD’s Flood Warning & Information Services program works with communities to achieve this vision by providing local officials with early notifications concerning heavy rain and flood threats in partnership with NOAA’s National Weather Service.  Local officials act on these notifications according to their respective emergency plans and warn people in affected high risk areas when a flooding threat becomes more likely.

In addition to providing flood predictions, UDFCD helps communities develop more efficient ways to detect and recognize flood threats.  The ALERT System is one reliable way to monitor weather conditions, rainfall and stream levels in real-time.  This early flood detection network is operated and maintained by UDFCD.  It is used extensively by emergency managers, public works officials, fire departments, law enforcement, meteorologists, hydrologists, engineers, local news broadcasters, and the general public.  NWS forecasters frequently make use of this valuable resource for issuing public flood advisories and flash flood warnings.

Twitter

Twitter users may want to follow this.  We are trying to keep the information simple to limit public confusion.

Automated tweets will be county-specific.  Additional hashtags like #flood, #cowx, #rain may be added.  If you are a Twitter user, you can start following this now.  Simply search for udfcd-fwp.  When heavy rainfall is detected by the ALERT System, you should receive something like:  Heavy rainfall occurring in ___(blank)___ County.

This text will be following by a link that points you to a “light” version of the ALERT GMap with very limited control features that looks like something this… http://t.co/MnVGlHjrdh.  Gmap-LT will show the measured rainfall amounts for the last 3 hours, a transparent looping radar overlay, and the current NWS warning polygons that link to the corresponding NWS warning text.  The rainfall measurement that triggered the tweet will blink (see demo).

Continue using http://alert5.udfcd.org for the ALERT GMap with user controls.

As always, we appreciate your feedback.

New ArcGIS Map

We recently improved one of our Esri ArcGIS Online maps that you may find useful.  The new map shows flood hazard areas, September 2013 flood peaks and hydrography for major drainageways within UDFCD.  Stream names can be displayed by clicking on the streams.  A link can be found on our ALERT System website from the Maps menu.
