The official definition of take includes the attempt or action to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect” threatened and endangered species.
Take may occur incidentally; meaning that take is “incidental to, and not the purpose of, the carrying out of an otherwise lawful activity.”

Normal years average
7,750 fountain darters (FD) taken in the Comal system per year
(USFWS).
7,750 * 8-years = 62,000
Drought of Record (DOR)
105,000 FD taken each year (USFWS).
105,000 * 7-years (remaining)= 735,000
62,000 + 735,000 = 797,000 FD take threshold in Comal System
