I think you could have 'floating pondweed' in the first picture and one of the species of milfoil probably Eurasian milfoil; there are several species. Second picture does have leaves similar to American pondweed. Some ponds/lakes can have two or more species of pondweed. Better pictures will help identify the plants. Kelly Duffie will be most familiar with pond weeds from TX.

See this for guidance for taking good pictures of pond weeds:
