2014 Drought Outreach Workgroup Triggers
These outreach strategies recommended, must have
a specific date, flow level, index well level, river
condition, or other defined trigger for implementation
or distribution.
Purpose of Presentation: To present a draft list of
potential specific dates, flow levels, index well levels,
river conditions, or other defined visual occurrence to
be used by the Implementing Committee to trigger
outreach
Next Steps:1. Workgroup members solicit input from
community and others
2. Discuss potential triggers and provide feedback to John Boggess for listing at next meeting
3. At 4/23 meeting, agree to final list of triggers

• Minimal flows in HCP• VISPO Triggers• ASR triggers• Critical Period• Agriculture Operations
and Conservation
• Recreation• Visual decrease in
flowing water• Loss of cultural or
economic opportunity• Water Conservation
Activities• Adaptive Mgmt due to
drought
• USGS Recharge Estimate (drought of record conditions)• Provision M of the ITP• Conservation Contracts
Concern/Milestone Trigger for Outreach response (Before)
Trigger for Outreach response (After) Spokesperson Community Affected Type of Media Key Elements of Messaging Prepared
Response
Spring Run 1 going ceases to flow
Flow @ Spring Run 1 < 5 cfs
NB- SM- SA- U/M-
New Braunfels / Entire Region
NB-KNBT (Interview) and Herald Zeitung SA- Express News SM- Social Media Uvalde/Medina- Factsheets and Table Tents
1. HCP is doing … to help…2. HCP slowed/prevented this from
occurring sooner by…3. Spring Run 1 is not “ideal”
habitat; rather Landa Lake is, and it still represents habitat in good condition.
4. Spring Run 1 is the first major spring to go dry in the Comal system and this was planned for and is part of the HCP
5. Definition of terms-Not dry but stops flowing
A, C, F…….
Minimum Flows @ SM and NB
SSA area in SM Refugia Triggers and at
different levels
VISPO ASR
Comal falls below 100 Sm Falls below 100
CPM Reductions Current and/or Future
Proactive Triggers
General positive “feel good” messaging at regular
intervals
1. Successes of HCP2. Initiatives by Regional
Stakeholders (SAWS ASR, SM/NB)
3. Conservation and education programs… etc.
