Having grown up in the Flint Hills and tall grass prairie of Kansas, I was in awe when when we moved to Minnesota, with its 10,000 (or 11,842) lakes dotting the landscape.  The fact that I now have a lake within walking distance of my house boggles my mind.  It’s like a dream to live in a state where you don’t have to be a millionaire to own, or spend the weekend, at a cabin by the water.

I don’t think Minnesotans realize how lucky they are.  We take our lakes, and rivers and streams, for granted.  Sadly, instead of being stewards of our precious waterways, many property owners build structures that harm our lakes, allowing chemicals and fertilizer to wash into the pristine water every time it rains, interfering with the natural wildlife and vegetation.  Not only that, people refuse to replace old septic systems which often cause the lakes where our children swim to be contaminated with human waste. Somehow, we expect our lakes to remain clean and healthy, existing purely for our weekend fun.

Recently, we had a chance to make people take more responsibility for keeping our lakes healthy, so it was depressing to read in last week’s Star Tribune that our governor has once again refused to take measures to care for our local treasures.   “It’s like a parting shot out to Minnesota — thumbing his nose at clean water after all these years, which is a dirty legacy to leave,” said Sen. Ellen Anderson, DFL-St. Paul and chair of the Senate environment, energy and natural resources budget committee.   In fact, our governor is taking care of his own political aspirations and his friends with environmentally-unfriendly lakeside mansions, while pretending to represent the average Minnesotan.

In the book “The Lorax”, by Dr. Seuss, the Lorax speaks for the trees.  Who will speak for our lakes, so that we can continue to enjoy them?  Who will speak for the natural resources you enjoy with your family?  It’s something to keep in mind come November.

For the next week or so, I’ve decided to blog about water.  National Geographic did an amazing job of writing about water and our world in April, and I’m going to participate in P&G’s Give Health “Clean Water Bloggivation”, not to win the trip to Africa, but because they’ll donate clean drinking water to people who need it, in return for participation in the program.  I’ll also blog about how you can make your own lake-front more environmentally friendly by planting a strip of native plants and grasses beside the water.

We spent last week in Iowa at a family reunion at lake Okoboji, a deep, clear, gorgeous lake near the Minnesota border.  My great grandparents had a cottage there, and every year my mom’s side of the family returns to spend a week swimming, fishing, going to the lakeside amusement park and just hanging out.

Gull Point is a pretty piece of land with a sandy beach and sandbar that juts out into the lake and is one of our favorite destinations. Each year we spend an afternoon or two there, swimming, skipping rocks and digging our toes into the sand.  We didn’t see many gulls this year, but there was a pretty white pelican hanging out nearby.  Little did I know that water birds carry a tiny parasite that infects snails in the water.  The parasite’s larvae are then released and swim around looking for a suitable mammalian host to burrow into and continue their life cycle.

Ignorant of the tiny bugs digging into our skin, we frolicked in the water for hours.

Humans are not a good host for these parasites and they soon die, leaving their buggy corpses under our skin.  Some people don’t have much of a reaction, but others have immunes systems that kick into high gear, rejecting the dead parasites with an inflammatory response in the the form of big, itchy, awful bumps.

My son is definitely allergic.  The CDC website has more information on Swimmer’s Itch, or Cercarial Dermatitis, which can also be found in many Minnesota lakes.  Generally, it doesn’t need much treatment except Hydrocortisone cream or Calamine lotion.  My daughter and I have a few itchy bumps, but nothing major.  My son, on the other hand is on oral prednisone too calm his allergic reaction.  Needless to say, it has been a long, long week.

According to the University of Minnesota’s Extension Service, you can do the following things to reduce your chances of getting severe swimmer’s itch:

• Dry off as soon as you leave the water. Rub skin briskly to remove water drops before they evaporate. Be sure to dry underneath waistbands and around leg openings. Encourage children to dry off thoroughly each time they leave the water.
• Shower with soap and fresh water or change into dry clothes as soon as possible.
• Don’t wade or play in shallow water. Swimming from a raft or pontoon minimizes your exposure.
• Don’t feed geese and ducks near your beach. Waterfowl are an important adult host for the parasites.
