Does anyone know why the following regulation was put in place? Just a bit curious on why such a small section of the river is closed. Is there a special stocking program taking place?

Regulation below:

A small portion of the West Branch Farmington River in the Riverton area from the intersection of Hogback Road and Route 20 in Hartland downstream to the gas pipeline crossing approximately four-tenths miles downstream of the confluence with the Still River in Barkhamsted will now be closed to all fishing from April First to 6:00 am on the second Saturday in April.
