The evidence is clear that the POA has mismanaged the hydrilla infestation in Lake Balboa. The hydrilla problem became apparent in spring 2016.
The POA’s first response to the problem was to try to harvest the hydrilla using a pontoon machine with a 4-foot underwater cutting blade. This approach became a problem when a loaded barge tipped over into Lake Balboa, i.e, fragments and tubers for re-establishment of hydrilla.
Then the POA put 1,000 sterile carp in Lake Balboa at a cost of $2,000 and recently followed up with 500 more.
Since there has been no evidence of any carp in my backyard, I then Googled “hydrilla” and was directed to a number of websites, including Texas A&M AgriLife Extension. The extension information is very helpful, since Texas has had a hydrilla problem for many years.
Texas A&M reports that: (1) harvesting hydrilla can be done, but any remaining fragments and tubers will result in the re-establishment of hydrilla; (2) grass carp can be effective, but require a range of 7-15 grass carp per surface acre; and (3) a chemical safe for fish, fowl and people can be sprayed on the water surface, but the water temperature must be 60 degrees or higher. Obviously, the latter is a missed opportunity for 2016, as cooler temperatures have arrived.
The grass carp approach is of interest because Lake Balboa is about 944 acres and would require at a minimum 6,608 grass carp. The 1,500 grass carp to-date is a drop in the bucket, i.e., only 22.7 percent of the minimum quantity needed to control hydrilla.
I don’t know who the “hydrilla experts” are at the POA, but it is obvious that the POA and its “experts” have and continue to mismanage the elimination of hydrilla in Lake Balboa. An initial Google search may have resulted in a more effective solution.
