With that much FA in the shallow bay the water in the pond should be clear. Correct? What is the water visibility depth? That amount of FA has removed a significant percentage of the nutrients from the pond, thus there should be less phytoplankton and more clear water.
Are you fertilizing the pond???
At this point for the amount of FA,,, IMO I would remove what ever you can physically remove from the main part of the pond without having a heart attack. Texas is a hot place. Maybe just do it a little at a time and in the evening or morning or during windy days. Remove what is practically feasible. Each scoop removed removes some FA bound up nutrients. Do you have a backhoe that you could use for a purchased or fabricate an algae weed rake??? Add a wide screen to a rake like that used in the video that replaces a bucket on a backhoe. https://www.youtube.com/shorts/6aRyrmyDc3A https://www.youtube.com/shorts/1n03a93FbCs
Put a type of screen webbing on this rake and mount it on a tractor or backhoe. Nice Wide rake for adding a webbing screen to remove FA
I would not be concerned with this amount of FA causing a whole pond DO kill since it is basically in the shallow bay part of the main pond. If it all died at once the loss of DO would be mostly in the shallow bay part of the pond. Worst case some fish in the shallow part could die. But many should find their way back out into open water as the main DO loss occurs. However without applying an algaecide (FA killer) rarely does all the FA die at once to cause DO shortages. FA blooms or masses usually naturally die gradually over week long periods and as the DO decreases I think most of the fish in that low DO region will seek deeper water of the open water 2 acres where DO is high especially if that water is clear with good normal density of clear water phytoplankton for DO production. The other good thing for your new pond situation is all the fish are still smaller and able to better tolerate periods of low DO at least for shorter periods such as 8 to 16 hours.
Keep an eye on it and keep us updated..
