Just some quick information for those interested. Hoping you and your family made it through Hurricane Ike safely and with limited damage.
As you are probably aware, the dam on Lake Conroe suffered damage from Ike. Approximately 1,500 feet of the 12,000 foot length of the dam needs “spot repair” at an initial estimated cost of $1 million. Before any repair can commence, engineering design for the repair must be completed, bids must go out to qualified contractors and a final bid must be accepted by the San Jacinto River Authority (SJRA) Board. The actual repairs will most likely commence by late-January and actual repair work is estimated to take 8 – 12 weeks. If the lake level must be lowered for repairs, SJRA does not see such an action occurring before late-January (with plenty of advance notification so that boat owners and lake area residents can prepare).
Based on the August, 2008 surveys performed by Texas Parks & Wildlife (TPWD), our weed and plant acreages are as follows:
· Hydrilla….1.3 acres (down from 2.5 acres in June)
· Water Hyacinth…..67.9 acres (down from 106.4 acres in June)
· Giant Salvinia…..628.7 acres (up from 283.5 acres in June)
· Combined native plants…..140.0 acres (down from 151.5 acres in June)
It appears that the White Amur purchased for Hydrilla reduction are now eating Water Hyacinth. Giant Salvinia is currently being treated with herbicides by SJRA and a contractor hired by SJRA.
An estimated 90,000 White Amur grass carp remain alive in Lake Conroe at this time. While certain organizations have suggested that the ban on removing White Amur from Lake Conroe be removed, the TPWD official in charge of Lake Conroe’s Aquatic Plant Management Program (Dr. Earl Chilton) has stated that this “ban” will not be removed at this time. Dr. Chilton sited that Lake Conroe is still infested with Hydrilla tubers from the 2,100 acre infestation we experienced in 2007 and that the White Amur will prove beneficial once these tubers start to grow again in Spring, 2009 and beyond. Hydrilla tubers can live dormant in the lake bottom for up to 5 – 7 years.
The Annual Meeting of the Lake Conroe Association (LCA) will be held at the offices of SJRA on Friday, January 16, 2009 from 10AM to Noon. Among other topics, the Board of Directors for the LCA for the upcoming year will be elected. More information on this meeting will follow as the date approaches.
