Most vegetation will maybe live but not thrive in water below 60F. Short retention time and small acreage will not produce very much food even with vegetation. Plant species that will thrive there will likely choke the entire 5-6ft depth zone maybe even down to 8ft deep. Short retention time prevents use of herbicides. Remember we are talking about only 0.1 ac. Basically a slow moving raceway as I understand the description.
