This problem hasn't been fixed because, well, people are still not prepared and do not take measures against the possibility of the "release of any teddy bears" or other animal of the stuffed kind ever did do that to another fish pond (Haines). Besides the ordinary precautions taken to prevent these kind of events from ever happening, they still somehow do. That was one small isolated incident. However, could you imagine how devastating it would be if that happened to a cities water or sewage lines? People couldn't get water and sewage would not be taken out of the city.
However, there is no need to panic. The is an simple and cost effective way to prevent any crisis like those described from ever happening. Proper protection of filters and water/ sewage line would leave any stuffed bear from entering and wreaking havoc. Covering all possible entry points of unintended material deposits would indeed make those bears think twice about laying their furry little paws on them and prevent them "from becoming a killer" (Fawcett). This would greatly decrease the possibility of of a clogged water main or filtration system.

Summary:Water flow in hatcheries is life support to the fish. Stop that flow, which delivers the dissolved oxygen required for fish respiration, and the fish suffocate and die. RELEASE OF ANY TEDDY BEARS into fish hatchery water is not permitted.
