The hydrology of the Braden River was altered in 1936 when the city of Bradenton created Ward Lake, a reservoir with an 838-foot (255 m) broad-crested weir 6 miles (9.7 km) upstream from the mouth. In 1985 the reservoir was expanded and supplies an annual average of 5.7 million US gallons (22,000 m3) of water per day.
The Braden River can be hydrologically divided into three distinct sections that include an 8.6-mile (13.8 km) reach of naturally incised, free-flowing channel; a 6.4-mile (10.3 km) reach of impounded river created by the Ward Lake reservoir and weir; and a 6-mile (9.7 km) reach of tidal estuary.
