Although states make specific laws governing water rights and the rights in land that borders water, most states generally follow one of two basic doctrines regarding water rights. Either riparian and littoral rights are automatically conveyed with property, or all water rights are controlled by the state under the doctrine of prior appropriation. The doctrine of prior appropriation is MOST likely to be followed in states where
a) Water scarcity is a significant concern.
b) Agriculture is the primary economic activity.
c) Waterfront properties are highly valued.
d) Urbanization is widespread.
