Status of a Freshwater Ecosystem after a Hurricane Event

Brook trout (Salvelinus fontinalis) are classic indicators of ecosystem health. They are very particular when it comes to where they can live. Brook trout were studied to determine how they and in turn, the stream system had recovered after Hurricane Irene in 2011. From July to November, water temperature were recorded using data loggers in six different locations in Styles Brook of the eastern Adirondacks. Two sets of dissolved oxygen readings were monitored at three sites. Brook trout were visually surveyed and underwater video was taken throughout the stream to document presence and behavior. Scales were safely taken from nine fish for aging. Stream bottom sediment was obtained in one heavily damaged area of Styles Brook to be analyzed. Kick-net surveys performed to determine the presence of stream bottom invertebrates. Temperature and dissolved oxygen were excellent for brook trout survival. Underwater video documented feeding and territorial behaviors by brook trout. Sediment revealed to be thousands of years old, evidence of damage caused by Hurricane Irene. Fish aging indicated trout being born in this stream after Irene. It was concluded that certain areas of Styles Brook can still support and propagate brook trout despite the devastation caused by Irene.
