Water Related Land Use (1986 to 1992) consists entirely of data generated from the "Slide Transfer Method" and there is no irrigation type recorded in the attributes. This layer was combined from multiple basin layers to create the earliest state wide layer. When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated.

Water Related Land Use (2010 to 2015) consists entirely of data generated from the "New Digital Method" and contains irrigation type and labels recorded in the attributes. This layer was combined from multiple basin layers to create the next state wide layer comprised entirely of the "New Digital Method" in which all basins have label and irrigation type information. When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated.

The water-related land use program is an effort by the Utah Division of Water Resources to quantify the acreages in the state of various land use types, especially those which are irrigated. Prior to 2017, land use was completed for a single basin each year. The present method is able to utilize historical line-work, attributes, and remotely sensed data to estimate acreage changes for the entire state in a single year.

Water Related Land Use (2002 to 2007) consists entirely of data generated from the "New Digital Method" and contains irrigation type and labels recorded in the attributes. This layer was combined from multiple basin layers to create the earliest state wide layer comprised entirely of the "New Digital Method" in which all basins have label and irrigation type information. When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated.

Water Related Land Use (2005 to 2010) consists entirely of data generated from the "New Digital Method" and contains irrigation type and labels recorded in the attributes. This layer was combined from multiple basin layers to create the next state wide layer comprised entirely of the "New Digital Method" in which all basins have label and irrigation type information. When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated.

Water Related Land Use (2000 to 2005) consists entirely of data generated from the "New Digital Method" and there are only some basins with irrigation type and labels recorded in the attributes. This layer was combined from multiple basin layers to create the earliest state wide layer comprised entirely of the "New Digital Method". When using multiple layers from these combined year state wide layers, please take care to verify that you do not duplicate data in certain basins due to how these layers have been generated.
