The concept of moving water from flood-affected areas to drought-stricken regions is not wacky. It's a feasible idea that has been implemented, often referred to as water reallocation or water transfer projects. Such projects involve diverting excess water from overflowing rivers or reservoirs during floods to areas facing water scarcity.

Here are a few examples of water transfer projects:

1. California Water Project (United States): This system transfers water from northern California, which is prone to flooding, to drier regions in the central and southern parts of the state.

2. South-North Water Transfer Project (China): This massive project aims to transfer water from the water-rich Yangtze River in the south to the arid north, improving water availability for agriculture and industries.

3. Murray-Darling Basin Project (Australia): The project involves regulating and distributing water from the Murray-Darling River system to manage water scarcity and floods in various parts of Australia.

4. Snowy Mountains Scheme (Australia): This project diverts water from snowmelt in the Snowy Mountains to the Murray and Murrumbidgee River systems for irrigation, hydroelectricity, and water supply.

5. Interbasin Transfer Project (India): India has several interbasin transfer projects to divert water from surplus river basins to deficient basins. For example, the Ken-Betwa Link Project aims to transfer water from the Ken River to the Betwa River.

These water transfer projects involve considerable engineering, environmental assessments, cost considerations, and negotiations among stakeholders. However, when well-planned and executed, they can provide a sustainable way to address water imbalances, mitigate flood risks, and improve water security in drought-prone regions.
