You are correct sir.
Most Texas lakes suffer the same problem.
Many (all?) of the public Texas lakes have large shallow areas that could be used for "grocery management".
Look at our neighbor states to see how their Wildlife Management builds de-watering areas.
Levees are built to allow draining of shallow areas and the planting of crops.
Typically these areas are leased to local farmers with the agreement that specific crops are planted and a percentage left at harvest time.
The gates are then opened and water fills to the desired depth prior to duck season.
So what's the problem with TPWD?
My thought - Texas is all about deer and the private land owner.
For example; Millions are spent on helicopter surveys and audits of private MLD ranches.
Why spend any money on stupid ducks.
And those migratory licenses you buy - If all you do is hunt waterfowl in Texas, you are getting ripped off my TPWD.
Ask the same question of Texas DU.
Their projects (your DU dollars) are always on private lands "donated" for a particular water enhancement or habitat improvement.
Name a public hunting lake in Texas that has been a DU project.
There are several DU projects you can hunt on in Texas. It's sad to see. TPWD always boasts how it has all this acreage of public hunting, yet the majority of it is not suitable for bird hunting, especially waterfowl. Then you look at projects in other states, and it is amazing the public hunting opportunities that are available.
Here is a link to all the DU projects in Texas
