There have been concerns voiced by anglers for many years about the loss of trout over the spillway at Four Springs Lake. While a spillway screen could prevent such losses it would also bring with it maintenance issues, as debris build up would likely compromise the efficiency of the spillway. The fish barrier nets in use at Lake Sorell for the carp project were seen as a practical solution. A spare piece of the nets used at Lake Sorell has been used to cordon off the spillway at Four Springs Lake thus reducing the likelihood of loss of fish over the spillway without compromising its efficiency. In April 2013 the net was put in place by the IFS.
