At the time of one of the surveys taken of the remains of Bayou Teche, it was noted that the wild vegetation of hydrilla hampered further investigations. Hydrilla is an invasive aquatic plant that originated in Asia, but has taken root in waterways all across the United States. Hydrilla affects water quality as it crowds out native species and impedes irrigation. It is also a nuisance to boaters and can foul up a boat propeller quickly if not careful.
