slough as opposed to 'slain'

This slough located along KTR moves water into the retention pond (one of others in the area) which is ultimately discharged into the St. Lucie River, spilling through a small concrete dam. A live tree leans over the water, with escape potential from the Vista Pines/Ocean Palms housing complexes. In-slough sediment and plant life sprouting from it are evidence that the slough is popular with regional wildlife. Fish inhabiting the slough/retention pond area can also be seen schooling in Krueger Creek, the St. Lucie River, and the Indian River lagoon -- the same individual fishes moving freely throughout the region's sloughs, ponds and canals into and out from the larger bodies of water.
