DNR TO CREATE SPECIAL STATE MAPS OF DATA FROM LAKES THAT FREEZE

IDEA:

STATES WITH LAKES THAT FREEZE SHOULD HAVE THEIR DNR CREATE MAPS WITH “MEDIAN LAKE ICE OUT DATES”

INSPIRED REFERENCE:

Minnesota DNR created a map of their state ice thickness data containing Safe Ice Thicknesses at a given time of year called “MEDIAN LAKE ICE OUT DATES” see: http://www.dnr.state.mn.us/ice_out/index.html?year=median

PURPOSE:

I would like to see all states (who’s lakes host ice recreational activities) create similar maps (like Minnesota’s) for their own lakes.

VALUE:

The (said map) is a valuable visualization tool that will enable:

1. State officials can more accurately plan the Ice Safety rules for their lake (e.g. thickness, and time of year to allow activities), discontinuation of activities, and post signs accordingly.

2. Families can more fully visualize known ice thicknesses and practice “safe ice habits” with this map, and also the knowledge presented by their own state DNR website.

KNOWN UNIQUE IMPLEMENTATION BARRIERS:

1. DATA COLLECTION: I discovered that not all ice is the same “Mohs hardness” due to admixing of minerals in a given lake.

2. LAKE PROPERTIES: Springs and other properties of the lake add to variable thicknesses.

3. REGIONAL FEATURES: Local climate and other endemic features must be factored in.

4. PRIVATE WATER BASINS: People participate in activities on local ponds and private ponds.

SOLUTION:

Designate the sites that will have ice thickness data collected monthly, and use this data to delegate which lakes are suitable for various recreational ice activities, then plot lakes and data to a map (like MN's map).

  1. I think this is a good idea for states with these types of activities.

    OTHER COMMENTS FROM THE “IDEA CREATOR”

    DISCLAIMER: I am not the creator of the Map idea, but rather bringing about awareness that Minnesota already has this system, it works well, and having uniform Map systems within other states DNR websites, that anyone can use, would be a good idea. (Other States would collect and represent their Ice data the same way as Minnesota) In concession, I fully recognize that (as far as priorities are concern), Mapping Lake Ice Data is definitely not the highest priority! However, I wanted to put this idea out there for the future => that is, for the future time and place that the right (resources and organizations) come together, and draw the conclusion that this data should be included within the Federal Geographic Data, and represented within a unified Map as relates to all relevant ice-forming States.

    TIPS:

    This future project could be managed by the Federal Geographic Data Committee

    http://www.fgdc.gov/ They would work in accordance with Executive Order 12906, as part of the National Spatial Data Infrastructure, creating “U.S. National Grid data” whereby:

    1. National policy, planning, framework, standardization, and appropriate processes would be agreed upon prior to initiating the project.

    2. State and Local level agencies and organizations (e.g. DNR) would be key trainers and data collectors, as well as, having other important duties intrinsic to forming a National Partnership, and continued dissemination to National databases.

    3. The U.S. Department of the Interior uses similar maps for hazard planning or other purposes and could monitor progress and conduct auditing.

    4. The U.S. Geographical Survey and Geospatial Program at the National Geospatial Technical Operations Center would contribute if not take a lead role (link http://nhd.usgs.gov/ ), and have created digital topographic maps with data relevant to this project including: The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD). This data would be useful for mapping purposes within the proposed program. Also see http://nationalmap.gov/ustopo/

    5. HAZUS-MH contains a Mapping system with capabilities that could fit many of the parameters necessary for the project. Integration of this system platform into the project is a future option to be considered.

    In the mean time, I created an Ice Safety Thread here:

    Enjoy as you wish!

  3. Good comment. Especially apropos since there is still some lingering ice on several Great Lakes after this brutally long and cold winter.
