LCRA Flood Operations Notification Service (FONS)

LCRA will call, email or text notice of flood operations at dams along the Highland Lakes and Lake Bastrop

​​LCRA offers a free service to notify subscribers when flood operations begin at dams along the Highland Lakes and Lake Bastrop.

The LCRA Flood Operations Notification Service (LCRA FONS) notifies subscribers of flood operations at dams by email, text and/or a recorded phone call. See the LCRA FONS Frequently Asked Questions.

Who should sign up for LCRA FONS?
Anyone who may be affected by flood operations or flooding along the Highland Lakes or lower Colorado River should register for LCRA FONS. This includes anyone who lives, owns property or operates a business on one of the lakes or along the river below Lake Austin.  Learn about LCRA dams and the Highland Lakes.

How do I sign up?
Complete the online registration form or call LCRA at 512-578-3246 or 800-776-5272​​, ext. 3246. The online registration takes about two minutes. All new subscribers must supply an email address, even if they are requesting notification by phone call or text only. If you do not have an email address, please call LCRA to complete your registration.

May I request a text, email and phone call notice, or do I have to choose one way?
You may request any or all of the notification options.

When will my subscription begin? How often do I need to register?
The term of the LCRA FONS agreement will begin 30 days after a registration form is received, and will continue through March 31, 2019. (All subscriptions in place as of March 31, 2017, have been extended through March 31, 2019.) LCRA may terminate this service at any time by providing 30 days written notice to the address provided on the registration.

How does LCRA FONS work? What dams are included?
LCRA FONS will email, text and/or call subscribers with a recorded message when flood operations are expected to begin or have begun at dams along the Highland Lakes (Buchanan, Inks, Wirtz, Starcke, Mansfield and Tom Miller) or Lake Bastrop.

LCRA will activate LCRA FONS as soon as possible, but in some circumstances, there may be little or no advance notice of flood operations. For example, if heavy rain falls on or near a lake, LCRA may have to begin opening floodgates before there is time to initiate LCRA FONS. (Inks Dam does not have floodgates and is designed for floodwaters to pass over its spillway; LCRA FONS is activated for Inks Dam when water flows continuously over the designated spillway.) 

The LCRA FONS notification will be for initial flood operations only, and not for each additional floodgate operation or for regular operations such as hydroelectric generation, gate testing and maintenance, or when LCRA moves relatively small amounts of water (equal to or less than would be passed through hydroelectric generation) downstream when the hydroelectric generating units are unavailable.

Why do I sometimes receive multiple notices from an LCRA FONS activation?
You will receive separate notifications for each dam and through each communication channel (text, email and/or phone call) you selected.

Will LCRA FONS warn me of impending floods? Will it tell me how high water will get in my area?
LCRA FONS is not a flood warning service. The service is a supplement to, and not a replacement for, vigilance on the part of residents and property owners. Anyone near the lakes or the Colorado River should monitor National Weather Service advisories, watches and warnings; local news media; and heed warnings from local emergency management officials when flooding poses a threat.
