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.

    Water Quality Sampling Data

    datahub.austintexas.gov | Last Updated 2024-09-24T08:28:56.000Z

    Data collected to assess water quality conditions in the natural creeks, aquifers and lakes in the Austin area. This is raw data, provided directly from our Water Resources Monitoring database (WRM) and should be considered provisional. Data may or may not have been reviewed by project staff. A map of site locations can be found by searching for LOCATION.WRM_SAMPLE_SITES; you may then use those WRM_SITE_IDs to filter in this dataset using the field SAMPLE_SITE_NO.

    Citizen Statewide Lake Monitoring Assessment Program (CSLAP) Lakes

    data.ny.gov | Last Updated 2024-03-01T18:08:08.000Z

    The dataset represents the lakes participating in the Citizen Statewide Lake Monitoring Assessment Program (CSLAP). CSLAP is a volunteer lake monitoring and education program that is managed by DEC and New York State Federation of Lake Associations (NYSFOLA). The data collected through the program is used to identify water quality issues, detect seasonal and long term patterns, and inform volunteers and lake residents about water quality conditions in their lake. The program has delivered high quality data to many DEC programs for over 25 years.The dataset catalogs CSLAP lake information; including: lake name, lake depth, public accessibility, trophic status, watershed area, elevation, lake area, water quality classification, county, town, CSLAP status, years sampled, and last year sampled.

    Major Water Sources in Iowa - Lakes

    mydata.iowa.gov | Last Updated 2023-08-30T20:46:27.000Z

    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.

    Iowa Geographic Names

    mydata.iowa.gov | Last Updated 2024-09-20T22:00:21.000Z

    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.

    A shapefile of freshwater water bodies hat have been sampled as part of the Nova Scotia Lake Survey. The Nova Scotia Lake Survey program is a partnership initiative between Nova Scotia Environment (NSE) and Nova Scotia Fisheries and Aquaculture (NSDFA) to inventory lakes throughout the province determining baseline water quality, in support of both sport fisheries and water resource management areas. The following weblink connects to a Nova Scotia Environment web map that includes the locations of the monitored lakes within the province and an alternative method for downloading the same lake chemistry dataset: http://nse.maps.arcgis.com/apps/webappviewer/index.html?id=7ded7a30bef44f848e8a4fc8672c89bd

    2016 Impaired Lakes of Iowa

    mydata.iowa.gov | Last Updated 2023-08-30T20:30:10.000Z

    This dataset represents centroids of lakes, reservoirs, and wetlands listed as "impaired" in Iowa's Section 305(b) Water Quality Assessment and the 303(d) Impaired Waters Report. Together, these two reports are known as Iowa's 2016 Integrated Report. Waterbodies in Iowa each have specific designations based on what they are commonly used for-recreation, such as swimming or fishing; drinking water; or maintaining a healthy population of fish and other aquatic life. Every two years, Iowa must report on its progress in meeting water quality goals to the U.S. Environmental Protection Agency (EPA). The state prepares one report called the 305(b) Water Quality Assessment or 305(b) list. This 305(b) list categorizes waterbodies to reflect: those that meet all the designated uses (category 1), those in which data availability is insufficient to determine whether any or all designated uses are being met (categories 2 and 3), and those waters in which the water quality prevents it from fully meeting its designated use, and is thus considered "impaired". New impairments (or category 5 listings) are placed on the "303(d) Impaired Waters Report", commonly referred to as the "impaired waters list." This is named after section 303(d) of the Federal Clean Water Act and means that the stream or lake needs a water quality improvement plan written (also known by a technical name, "Total Maximum Daily Load," or "TMDL"). The water quality improvement plan outlines water quality problems, identifies sources of the problem(s), identifies needed reductions in pollutants and offers possible solutions. Water quality improvement plans are approved by the EPA and then the waters are moved from the 303(d) list back to the 305(b) list as category 4 listings (waters considered impaired, but a water quality improvement plan has been written).
