Harmful Algal Blooms (HAB)

What are Harmful Algal Blooms (HAB)?

Algae are important to the lake ecosystem, and most species of algae are not harmful. Algal blooms occur when certain types of algae grow quickly in water, often in response to increases in nutrients and hot, dry, still weather conditions. Some species of algae (blue-green algae, also called cyanobacteria) intermittently release toxins, harmful to the health of the environment, plants, animals, and people.

How do the toxins in HAB cause illness?

Rarely, there may be skin rashes or itching. Mostly, however, the toxins must be ingested to be a problem. Therefore, for the most part, it is safe to swim in areas of the lake that are clear.   But, be reasonable;  do not swim through algal bloom. Do not allow small children to play in shallow water that is not clear. Keep pets out of these areas.  Do not drink lake water. When in Doubt, Stay Out.

What can I do to decrease or prevent algal blooms?
Don’t add nutrients to the lake:

  • Use only phosphorus free fertilizers (middle number is zero) and use them sparingly
  • Plant a buffer zone of deep rooted grasses, shrubs, or natural vegetation at the shoreline.
  • Have your septic system inspected and pumped at least every 3 years.  Make repairs promptly and, if necessary, replace outdated or  ineffective systems
  • Use phosphate-free laundry and dishwashing soap
  • Compost or properly dispose of leaves, lawn clippings, garden waste, goose poop, etc. Not in the lake, please!

CSLAP monitoring, Roaring Brook Lake, and HAB documentation

For eight years, Roaring Brook Lake has participated in CSLAP, an intensive NY state lake monitoring program. One benefit of our participation in the program is our lake’s access to expertise and testing when a problem is suspected. At different times in past summers, residents have identified areas suspicious for HAB which have been sampled.

Regatta — Pay in Advance

FAQ:

UNTIL WHEN CAN I BUY THE DISCOUNT $5 WRISTBAND?

We’ve extended the time to Friday morning at 9 am.

The PayPal button will only be available until then.  After 9 am Friday, the button will no longer function and you will no longer be able to buy a discounted wristband.

Wristbands will still be available for purchase at the gate, but they will be full price, $10 each.

HOW DO I PAY IN ADVANCE FOR A WRISTBAND?

Go above or to the right of your screen and look for the section labeled Regatta 2017. Look for the scroll-down and choose the number of people age 7 and over who you would like to register. Add the names to make it easier for the volunteers on Regatta Day.  Then, click on the yellow “Buy Now” button. Next, choose to pay with PayPal or a credit card. PayPal is first, credit cards are below, you may need to scroll down to see the credit card area.

 WHY HAVE WE CHANGED THE WAY WE DO PAYMENT FOR THE REGATTA?

Several reasons:

  • For most families, Regatta will cost less than previous years (if you pay in advance)
  • You won’t have to bring cash to the Regatta
  • There will be less food waste.
  • It will make things easier for the volunteers who are working hard to make it a great day.

 CAN I EAT ALL I WANT?

Yes! All that great food is included in the price of one wristband.

 CAN I BRING MY FRIEND FOOD OR A DRINK?

No. Sorry, you can only get food and drinks for yourself.
Otherwise, we won’t have enough!

 WHY IS THE WRISTBAND SO MUCH MORE EXPENSIVE AT THE GATE?

We hope you’ll buy in advance. We’d like to know how many people are coming.
It’ll save you money and it will be easier for you on the day of the Regatta.
We’ll check you off on the list, give you your wristband and you’ll be all set for a great day!

 WHAT IF MY WRISTBAND FALLS OFF?

It won’t. I’s sturdy and waterproof
If your wristband is tampered with or off your wrist we can’t honor it.

 I ONLY WANT A HOT DOG. CAN I BUY IT SEPARATELY?

Sorry, you will need a wristband to get food or drink of any kind.  Save money, help us be organized, buy your wristband in advance for $5.
