Campaign: Topic 3: Analysis, Tools and Information for Risk Reduction Decision-Making

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).
