In recognition that the waters of Connecticut are a precious, finite and invaluable resource upon which there is an ever increasing demand for present, new and competing uses; and in further recognition that an adequate supply of water for domestic, agricultural, industrial and recreational use and for fish and wildlife is essential to the health, safety and welfare of the people of Connecticut, it is found and declared that diversion of the waters of the state shall be permitted only when such diversion is found to be necessary, is compatible with long-range water resource planning, proper management and use of the water resources of Connecticut and is consistent with Connecticut’s policy of protecting its citizens against harmful interstate diversions and that therefore the necessity and public interest for sections 22a-365 to 22a-378, inclusive, and the protection of the water resources of the state is declared a matter of legislative determination.
