Amend HB 2915 by striking all below the enacting clause and 
substituting the following:
	SECTION 1.  Section 11.085(p), Water Code, is amended as 
follows:            
		(1)  A river basin may not be redesignated in order to 
allow a transfer or diversion of water otherwise in violation of 
this section.   However, this section does not prevent the Board 
from redesignating a river basin as part of another river basin 
based on scientific or hydrologic evidence the Board finds supports 
the redesignation if the confluence of the two basins is upstream of 
the receiving bay and estuary system, whether or not the 
redesignation facilitates a transfer or diversion of water.  If the 
Board combines two river basins under this subsection, any transfer 
of water between the basins that are combined shall be evaluated as 
a new appropriation for purposes of determining appropriate 
conditions to protect the environment.  If the Board combines two 
river basins under this subsection, any transfer of water between 
the basins that is facilitated by the combination of the basins 
shall be junior to all water rights granted before the application 
for transfer is accepted for filing if the project for which the 
transfer is sought includes the pumping and transport of 
groundwater between the two river basins as the river basins were 
constituted on January 1, 2005 unless the water is pumped from 
within a groundwater conservation district or if there is no 
groundwater conservation district where the water is pumped, in 
compliance with the most stringent spacing and production rules of 
groundwater conservation districts in contiguous counties.
	SECTION 2.  This Act takes effect immediately if it receives a 
vote of two-thirds of all the members elected to each house, as 
provided by Section 39, Article III, Texas Constitution.  If this 
Act does not receive the vote necessary for immediate effect, this 
Act takes effect September 1, 2005.
