Bonham Mayor Roy Floyd says the North Texas Water Authority will begin construction of the Lower Bois D'Arc Creek Reservoir late this year or in early 2016. The lake will be 16 miles long and eight miles wide, from near Honey Grove to Lake Bonham. The lake has been in the development stage for about 30 years, the mayor says. Also, construction of Ralph Hall Lake near Ladonia is expected to begin in about a year, according to Mayor Floyd.
