Elected and appointed officials are not likely to come up with a coherent or common sense long range plan to deal with the worsening issues of water on this continent. Some for lack of a real life perspective of the problem. Some influenced by large amounts of money from those that stand to profit from water, and the continuation of the political insanity in America.
Any way we look at it, it is a giant problem. In 2015 terrible drought from Arkansas to the west coast, Massive floods from Texas to the east coast.
Giant dams and water systems are not the answer, but a vast continent wide system of local and regional, small and medium water control systems to store, control, move, clean, and use this water, as well as produce electricity to move this water.
Using Hydrodynamic systems, Siphon systems, ram pumps, archimedes pumps,
Also we must refill our water tables. Agricultural systems like permaculture will help slow flooding, along with infiltration ponds and water storage and control systems to move water to the driest places at the time of great rains and floods.
Micro-hydro Electric systems for pumping water and electricity.
Ram pumps, for moving water up hill. Refilling the water table of the whole continent is of paramount importance.
First to deal with the water problem we must end the destruction of our water, Fracking, tar sand extraction and so on. Agriculture in the style of war, glyphosate herbicide also called roundup has many problems, including binding minerals in the body making them unavailable in the process of turning good fats into hormones. 2,4-D which is half of the agent orange defoliant used in the Vietnam war and known to cause cancer. Atrazine which is know to cause frogs to spontaneously change sex and to cause breast, uterine and testicular cancer, etc. Many are Biocides and, or cause endocrine disruption, that are destroying our ocean and the health of our people and biosphere generally. Industrial pollution and plastic going into the oceans.
We must have
Many vast constructed wetlands on rivers and streams to remove nitrogen, phosphorus and other chemicals and things like plastic, etc, before this water gets to the oceans.
We must come up with a plan to capture as much of the Methane coming out of the permafrost and arctic ocean areas.
Reforestation of the continent from the west to the east. Prevailing wind is mostly from the west in North America in summer. Trees are a great way to get water in the air and are an excellent way to suck carbon out of the atmosphere.
Regenerative and restorative agriculture systems. Not just sustainable agriculture.
