The Water Code authorizes the Texas Commission on Environmental Quality to cancel surface water rights in whole or in part if all or part of the water has not been put to beneficial use over a period of 10 years. The law, however, exempts water rights from cancellation in certain specified situations. House Bill 1225 amends the Water Code to create a cancellation exemption to the extent that nonuse resulted from the implementation of water conservation measures under a water conservation plan, as evidenced by implementation reports. The bill and exemption apply not just to future cancellation proceedings, but to those pending as of the bill's effective date.
