Land Area

Water Area

Land area is a measurement providing the size, in square miles, of the land portions of geographic entities for which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the Census Bureau's geographic database. Land area is based on current information in the TIGER® data base, calculated for use with Census 2010.

Water Area figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, reservoir, pond, or similar body of water that is recorded in the Census Bureau's geographic database. It also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a two- dimensional feature (rather than as a single line). The portions of the oceans and related large embayments (such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland water from the point beyond which they are narrower than 1 nautical mile across. Identification of land and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not necessarily reflect their legal definitions.

    Iowa Perpetual Care Cemeteries

    mydata.iowa.gov | Last Updated 2023-08-30T17:12:35.000Z

    According to Iowa law, a “Perpetual Care Cemetery” is a cemetery which has established an irrevocable trust fund for the maintenance, repair, and care of all interment spaces, features, buildings, roadways, parking lots, water supply, and other existing cemetery structures. All new cemeteries that were organized or that commenced business in Iowa on or after July 1, 2005, must operate as a perpetual care cemetery. Cemeteries that were organized before that date may or may not be perpetual care cemeteries. This dataset provides a list of perpetual care cemeteries registered with the Iowa Insurance Division.

    Iowa Watershed Boundaries: Subwatersheds (HUC 12)

    mydata.iowa.gov | Last Updated 2023-12-05T18:03:00.000Z

    The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS). Hydrologic units are given a Hydrologic Unit Code (HUC). For example, a hydrologic region has a 2-digit HUC. A HUC describes where the unit is in the country and the level of the unit. "A hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Its boundaries are defined by hydrographic and topographic criteria that delineate an area of land upstream from a specific point on a river, stream or similar surface waters. A hydrologic unit can accept surface water directly from upstream drainage areas, and indirectly from associated surface areas such as remnant, non-contributing, and diversions to form a drainage area with single or multiple outlet points. Hydrologic units are only synonymous with classic watersheds when their boundaries include all the source area contributing surface water to a single defined outlet point."

    Iowa Geographic Names

    mydata.iowa.gov | Last Updated 2024-05-17T22:00:20.000Z

    This dataset provides the geographic names data for Iowa. All names data products are extracted from the Geographic Names Information System (GNIS), the Federal Government's repository of official geographic names. The GNIS contains the federally recognized name of each feature and defines its location by State, county, USGS topographic map, and geographic coordinates. GNIS also lists variant names, which are non-official names by which a feature is or was known. Other attributes include unique Feature ID and feature class. Feature classes under the purview of the U.S. Board on Geographic Names include natural features, unincorporated populated places, canals, channels, reservoirs, and more.

    Outstanding Iowa Waters

    mydata.iowa.gov | Last Updated 2023-12-05T18:09:14.000Z

    Antidegradation refers to federal and state regulations designed to maintain existing uses of surface waters and to protect high quality waters from unnecessary pollution. An Outstanding Iowa Water (OIW) is defined as the following: "A surface water that IDNR has classified as an outstanding state resource water in the water quality standards." An OIW receives Tier 2 ½ protection. Tier 2 ½ Review is defined as follows: "Policies and procedures that prohibit any lowering of water quality in unique waters as identified in the water quality standards unless the lowering is temporary and limited, results from expansion of existing sources, or serves to maintain or enhance the value, quality, or use of the OIW, as determined by the Director of IDNR on a case-by-case basis."

    Major Water Sources in Iowa - Streams

    mydata.iowa.gov | Last Updated 2023-08-30T20:59:31.000Z

    The Major Water Sources list was created by IDNR to address concerns that new confinements would be constructed within view of "floatable/canoeable" rivers. The definition of major water source in Iowa Administrative Code - Natural Resource Commission - Chapter 65 is: "a water source that is a lake, reservoir, river or stream located within the territorial limits of the state, or any marginal river area adjacent to the state, if the water source is capable of supporting a floating vessel capable of carrying one or more persons during a total of a six month period in one out of ten years, excluding periods of flooding." The list was created by getting the counties to identify "canoeable" streams and with additional input from DNR staff.

    Combined dataset of all wells with uniform attributes from detailed individual well databases. This dataset is intended to serve as a metadata-level well database. Large overlaps are known to exist among databases; however, all are preserved as found in order to preserve program-specific information. For example a well may derive geologic data from the Geologic Sampling Points database, public water supply data from the SDWIS Wells database and Water Allocation information from the Water Use (WACOP) database. Each of these will be represented by a record within this dataset.
