Last week the flow of water from Benbrook Lake into the Clear Fork of the Trinity was shut off for maintenance, reducing the river to mere pools and mud flats in some areas. Land animals—herons, egrets, killdeers, crows, raccoons—took advantage of the situation to go fishing. Water animals—turtles, fish, mussels, crawdads—had to seek deeper water. The tracks in the mud left by both sets of animals wrote their story of migration.
