Bay-mouth bars may extend partially or entirely across the mouth of a bay; bay-head bars occur at the heads of bays, a short distance from shore. If the supply is not interrupted, and the spit is not breached by the sea (or, if across an estuary, the river), the spit may become a bar, with both ends joined to land, and form a lagoon behind the bar. Activities such as logging and farming upstream can increase the sediment load of rivers, which may hurt the intertidal environments around spits by smothering delicate habitats.
