Alternative Water Sources

ALTERNATIVES:  How could the amount of water to be drawn from Lake Conroe in the future be reduced?  “Alternatives” include:

  • Water conservation will be an integral part of reducing the amount of water drawn fromLakeConroe.  If we use less water, then we won’t have to draw as much.  Since a maximum of 100,000 acre feet per year can be drawn fromLakeConroeand more water than that will be needed someday, water conservation will be with us forever.  For a separate discussion of this, see “Water Conservation” below.
  • Utilizing waste effluent from treatment plants for irrigation will reduce our water use.  In summer months, it is estimated that 60% of our residential water use goes to irrigation (watering your yard and landscape).  In the winter, that estimate is 30%.  While it may be difficult to convert existing subdivisions and commercial development into users of effluent for irrigation (since the construction and infrastructure is already in place), new construction could much easier accommodate the use of effluent for irrigation by incorporating this concept into the planning stage of that development.
  • Further consideration must be given to Judge Sadler’s proposal of building two new reservoirs to capture water that would otherwise be released over the dam on Lake Conroe or lost elsewhere during periods of heavy rainfall.  Conceptually, these two reservoirs would capture water before it gets toLakeConroe.  If Lake Conroe were not full (at the 201 feet level), then the water would be allowed to flow into Lake Conroe.  If Lake Conroe were full and excess rains would be otherwise released downstream, these reservoirs would capture the water behind dams and hold it there until Lake Conroe needed it to fill the lake to the 201 feet level (normal pool elevation).  Clear obstacles to this proposal include the procurement of the land for the creation of the two reservoirs (some of which would have to come from the Sam Houston National Forest) and the multitude of environmental concerns related to such a project.  The cost of such a project has not yet been determined.  SJRA has agreed to conduct a feasibility study of this proposal, but a study date earlier than 2015 has not been agreed to yet by SJRA.  Approvals for and construction of such reservoirs would probably take a minimum of 20 to 30 years (remembering that our County’s water needs will be here forever).
  • Many have suggested that an “alternative” might be building a reservoir between Lake Conroe and The Woodlands which captures all water released over the dam atLakeConroe.  This “alternative” has been discounted based on the lack of a suitable site.  To be cost effective and practical, this reservoir would require too much land given the lack of undeveloped land between Lake Conroe and The Woodlands.

LCA PRESIDENT’S UPDATE

It has been a beautiful, yet dry, Fall season so far.  I hope you’ve made your way outdoors to enjoy the lower temperatures, lower humidity and endless sunshine we’ve shared for the past six weeks or so.  But with “the good” usually comes “some bad”.  Officially in the Lake Conroe area, we’ve had only 2.83 inches of rain since September 1 and the lake level has dropped to a level of 199.36 as of today.  At this level, the lake is 1 foot 8 inches below its normal pool elevation of 201 feet.  Please be careful out there boating as submerged debris and stumps are much closer to the surface when the lake level is down.

With the lack of rainfall and dry conditions, Montgomery County was officially placed under a Burn Ban as of October 25.  Please resist burning your leaves or lighting that Fall bonfire as conditions are extremely hazardous.

The Lake Conroe Association (LCA) initiated its Annual Fund Raising Campaign on June 10 and identified its primary, immediate need to be monies to fund a study by Texas A&M University which will review future lake levels once water starts being removed by the San Jacinto River Authority (SJRA) in 2016 (further discussion of this Texas A&M study follows).  The LCA agreed to pay $66,000 of the $142,000 total study cost; with the balance funded by Montgomery County, the Cities of Conroe and Montgomery, various MUD’s, Lake Conroe Communities Network (LCCN) and other lake-related donors.  LCA’s Annual Fund Raising Campaign has raised $57,585 to date and $8,415 was paid from the LCA’s reserves to meet that $66,000 obligation.  We greatly appreciate the continued generosity of our LCA Members in donating $57,585 during these difficult economic times.  Should you have missed the LCA’s Annual Fund Raising Campaign and still desire to contribute, monies can be mailed payable to the “Lake Conroe Association” at PO Box 376, Willis, Texas  77378-9998.

The contract between Texas A&M University and Montgomery County for the above-referenced Lake Study was approved by Commissioners Court and executed by Montgomery County on September 27.  With SJRA prepared to initiate significant water removal in 2016 yet stating that the effects on Lake Conroe’s lake levels will be “minimal”, the Lake Study will review engineering studies commissioned by SJRA in an effort to understand and validate (or not validate) SJRA’s conclusions on future lake levels.  Should Texas A&M’s study conclude that lake levels may drop lower than predicted by SJRA, Texas A&M will also study the economic impact on our community, and Montgomery County as a whole, of lower lake levels.  The 16 month “Timeline of A&M Study of Economic Impact of SJRA’s Planned Lake Level Reductions” includes reviews of lake level studies, property value assessments, and sales tax revenue data; and also includes a survey of residents, business survey and a contemplated Town Hall Meeting.  The Lake Study including all elements listed here is to be completed by December, 2011.

As you’ve most likely read, water conservation has become a key element in both reducing our overall water consumption and potentially helping maintain lake levels in Lake Conroe.  LCCN (a local community organization) has spearheaded the water conservation topic and held several presentations to elected officials, MUD’s, and interested parties.  For more information about LCCN and their work on water conservation, you may review their website at www.lakeconroecn.com.

An invasive species named Zebra Mussels have been identified for the first time on Lake Conroe.  Zebra Mussels multiply quickly and have damaged many bodies of water in the U.S. and around the world (causing clogged intake pipes, damaging boat hulls, creating sharp surfaces on boat docks and lake floors, and altering water chemistry).  Fortunately, this case of Zebra Mussels was identified on the hull of a boat BEFORE it was launched into Lake Conroe thanks to an observant marina owner (and LCA Board Vice President).  In conjunction with Texas Parks & Wildlife and SJRA, the LCA has contributed $1,250 towards the creation and installation of 250 permanent signs around Lake Conroe at various access points to educate the public on the importance of inspecting your boat hull before launching that boat into any body of water.  For more information on Zebra Mussels, you can access www.texasinvasives.org.

Texas Parks & Wildlife completed its survey of aquatic vegetation on Lake Conroe in July, 2010 and reported only 0.02 acres of Hydrilla, 1.79acres of Giant Salvinia and 1.16 acres of Water Hyacinth…..ALL GREAT NEWS !!  Native vegetation (natural, beneficial plants) held steady at 150.21 acres.  Many thanks are due Texas Parks & Wildlife and SJRA for their efforts in controlling invasive aquatic vegetation on Lake Conroe, and to our LCA Members who have donated over $500,000 over the past four (4) years towards this cause.

As you may be aware, the primary method of controlling Hydrilla (which covered over 2,000 surface acres of Lake Conroe only two years ago) has been the purchase of 130,000 White Amur Grass Carp.  Based on a 32% estimated mortality per year and the fact that this species has been genetically-engineered so as not to produce offspring, Texas Parks & Wildlife (TPWD) estimates that 48,000 were still alive on May 31, 2010 and projects that 32,000, 22,000 and 15,000 grass carp will be alive on May 31 of 2011, 2012 and 2013, respectively.  When asked how it will calculate when to start adding new White Amur Grass Carp to Lake Conroe, TPWD responded “As soon as Hydrilla starts to expand into water beyond a few inches deep, it will likely be time to add more grass carp.  At that point, stocking calculations will be based on returning the number of grass carp per total surface acre to the most recent survey where Hydrilla was totally under control.  In this way, we hopefully will remain in a proactive mode instead of a reactive mode.”  The LCA meets regularly with TPWD and SJRA to discuss aquatic plant surveys and means by which to maintain a healthy Lake Conroe.

Well, that’s it for another edition of our LCA President’s Update.  You can review previous editions of these LCA President’s Updates, follow current topics of interest, and send us your comments at our website at www.lakeconroeassociation.com.  We’re wishing you a wonderful Fall season on the lake and thank you for your continued support.
