Environment
The Shoalhaven River and its main tributary the Kangaroo River were once renowned as an Australian bass fishery. Unfortunately, Tallowa Dam has been a potent barrier to migratory native fish with estuarine/marine juvenile stages, blocking species including Australian bass from more than 80% of their former range in the Shoalhaven system. Recent stockings of hatchery-bred Bass in Lake Yarrunga are an attempt to remediate the situation. A fishway for Tallowa Dam was completed in August 2009. This fishway is designed to allow for the movement of bass and other native fish over the dam. Lake Yarrunga has also suffered the illegal introduction of highly damaging exotic carp, which are now present in high densities.

Famous quotes containing the word environment:
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“Modern man’s capacity for destruction is quixotic evidence of humanity’s capacity for reconstruction. The powerful technological agents we have unleashed against the environment include many of the agents we require for its reconstruction.”
—George F. Will (b. 1941)
“Today the young actors regard their environment with rage and disgust. They regard their Master not as disciples regard their Master, but as slaves regard their Master.”
—Judith Malina (b. 1926)
