What year did the Reclamation Reform Act raise the land ownership limit for low-cost federal water?

The Reclamation Reform Act, enacted in 1982, was a significant piece of legislation aimed at reforming the allocation and usage of water resources in the western United States, particularly in relation to federal irrigation projects. One of the key components of the Act was the adjustment of the land ownership limits for individuals and entities able to receive low-cost federal water for irrigation.

Before the 1982 reforms, there were restrictions on the amount of land that could be owned by one individual or entity in order to ensure equitable access to federal water supplies. The Reclamation Reform Act raised these limits, allowing for greater land holdings, which was seen as a way to modernize agricultural practices and increase efficiency in water usage.

In the context of California's water issues, this change was particularly important as it allowed larger agricultural operations to benefit from federal irrigation resources, thereby reflecting broader trends in agriculture and water management during that time.

The other years listed do not correspond to the enactment of the Reclamation Reform Act; therefore, the year 1982 is established as the correct answer.
