minimum flows between Years 12 and 14 ofthe permit.
3. Carnal Springs (flows being considered and modeled)
a. 30 cfs monthly average
b. 30 cfs daily average (translates to 45 cfs monthly average)
c. 50 cfs daily average (translates to 65 cfs monthly average)
4. San Marcos Springs (flows being considered and modeled)
a. 45 cfs monthly average
b. 45 cfs daily average (translates to 53 cfs monthly average)
c. 65 cfs daily average (translates to 73 cfs monthly average)
IV. "Bottom Up" Approach
1. The "bottom up" approach stacks up non-engineered solutions to get as close as possible to the
flow targets and then uses an engineered solution to close the "gap." (Attachment 3)
2. A Stage V reduction in the Critical Period Management ofthe Edwards Aquifer is being
considered:
a. Max pumping during Stage V = 320,000 acre-feet.
b. Stage V is intended to be a reduction that is triggered only when all else has failed to slow
the reduction of springflow during a severe drought.
c. Trigger J -17 water level of 625 feet
V. New Braunfels Concerns
Questions Facing New Braunfels
1. Flows - Does the City of New Braunfels support the minimum flows of 30-65cfs monthly average
that are being recommended for Carnal Springs by the EARIP? Flows from Carnal Springs would
only reach these minimum flows during the drought of record (drought of the 1950's). Important
points to note: currently in the drought of record flows would be anticipated to reach 0 cfs, a
minimum flow of 30 cfs monthly average represents dry spring runs but water in the main body of
Landa Lake and the old channel, and current flows during Oct /Nov 2010 have been around 325 cfs.
2. Does the City of New Braunfels support Environmental Protection and Restoration Areas proposed
by the EARIP to be built in Landa Park (Attachment 2)? The EARIP has acknowledged publically
the aesthetic, economic, and cultural importance of Landa Park, and understands that all designs
would have to consider these points.
3. Does the City ofNew Braunfels support Recreation being a covered action in the Habitat
Conservation Plan? A covered action is an action that is assumed to cause take of the Endangered
Species and is requested to be covered in return for mitigation and minimization efforts reducing the
take and benefiting the effected Endangered Species.
