The City of Houston
and the San Jacinto River Authority seek authorization to divert and use 32,500
acre-feet of water per year out of the firm storage in Lake Houston for
municipal and industrial purposes at a maximum combined diversion rate of
465.69 cfs (209,000 gpm).After analysis
of the updated WAM (2002) for the San Jacinto River, the yield of Lake Houston
was determined to be approximately 200,500 acre-feet per year.This application requests the appropriation
of 32,500 acre-feet per year of firm yield remaining in Lake Houston at a
reliability of 100%.
2)COA No. 5809A - Reuse of Groundwater Based Return Flows from
Wastewater Treatment Plants
The San Jacinto
River Authority (SJRA) seeks authorization to divert and reuse not to exceed
14,944 acre-feet of their existing groundwater based return flows and any
future groundwater based return flows from their three wastewater treatment
plants in the San Jacinto River Basin for municipal and industrial purposes at
a maximum diversion rate of 155.97 cfs (70,000 gpm).SJRA also seeks authorization to use the bed
and banks to convey the water downstream from their wastewater treatment plants
to their diversion point on Lake Houston authorized in a previous permit.

not to exceed 80,000 acre-feet of run of the river water from three diversion
points in Lake Houston for municipal and industrial purposes at the maximum
combined diversion rate of 465.69 cfs (209,000 gpm).The updated WAM (2002) for the San Jacinto
River indicates that the reliability of this water right application is
approximately 55% to 57% based on Scenario 3 (full use of water rights with no
return flows) as defined by TCEQ.The
water will be used as a secondary source to improve the systems operations
between Lake Conroe and Lake Houston.

Jacinto River Authority seeks to amend COA 08-4279 by; 1) adding industrial and
municipal purposes, 2) adding an additional existing upstream diversion point
(CWA pump station near Dayton; about 20 miles upstream), and 3) right to use
