Description: Point locations and descriptions of quantitative Interim Instream Flow Standards (IIFS) for Hawaiian streams as of October 2024. Description: The Interim Instream Flow Standard is the quantity or flow of water or depth of water which is required to be present at a specific location in a stream system at certain specified times of the year to protect fishery, wildlife, recreational, aesthetic, scenic, and other beneficial instream uses. Under the State Water Code (Code), Chapter 174C, Hawaii Revised Statutes (HRS), the Commission on Water Resource Management (Commission) has the responsibility of establishing IIFS on a stream-by-stream basis whenever necessary to protect the public interest in the waters of the State.

Description: Aquifer Sector Area and (smaller, sub-region) Aquifer System Area boundaries, as determined/defined by the State Department of Land and Natural Resources, Commission on Water Resource Management to provide a consistent basis for managing ground water resources. Data updated June 2022.
Aquifer sector and system area boundaries were adopted to provide a consistent method by which to reference and describe ground water resources and to assist in various water planning efforts. These boundaries are not meant to be interpreted as absolute hydrologic boundaries. For more information on aquifer area boundaries, aquifer descriptions, and sustainable yields, please refer to the Hawaii Water Plan, Water Resource Protection Plan Update, 2019. Note: The Hawaii State Department of Health maintains another GIS aquifer layer, which is more resource-oriented in nature, and which has different boundaries than the CWRM version, which is more administrative in nature.

Description: Hawaii Groundwater Aquifers (DOH Version), Revised version (June 2011) of DOH aquifer shapefile. The attribute data represent aquifer type codes and status codes that describe an aquifer's geology and status (ie. development stage, utility, salinity, uniqueness, and vulnerability). (Note: DLNR maintains another version of aquifers, which is more administrative in nature, and which has different boundaries than the DOH version, which is more resource-oriented in nature). Hand-digitized and coded by DOH Groundwater Protection Program, Environmental Planning Office from 1:24,000 scale maps provided by John F. Mink and L. Stephen Lau of the University of Hawaii Water Resources Research Center, 1987. Reference: "Aquifer Identification and Classification for O`ahu: Groundwater Protection Strategy for Hawai`i" November 1987.

NOTE: If you need to determine whether your parcel/project is above or below the UIC line, please contact the DOH Safe Drinking Water Branch (SDWB) at (808) 586-4258. This layer should be used ONLY as a low resolution/rough cut approximation of where the UIC lines are located. May, 2023 - Data is still current, per DOH SDWB. Upon request by the State DOH SDWB, the GIS Program made several modifications to this layer. 1. Created a uic_line layer from the uic_poly layer to reduce confusion when using the layer to depict and refer to the UIC "LINE" and to enable more straightforward symbolization of the layer. 2. Changed the UIC_Code attributes in the uic_poly layer from a numeric code field to a text field in order to add clarity to the meaning of the attribute values (whether the area was above or below the UIC line). The uic_poly layer is being kept in place to allow for easier analysis.

"Restricted Watersheds" are those watersheds where water supplies are vulnerable to contamination by public access and are therefore restricted from public access. Access to those watersheds requires permits.
