In regards to phosphorus, Ehrman, an avid fisherman who has spent more than 30 years on Moose Pond, says the water is not as clean as it used to be.

"These to be a lot of white perch," he says. "You don't see them any more. Plus, fishermen aren't catching the salmon like they used to."

Excess phosphorus is the beginning of a vicious cycle in a lake. Colin Holme, field service director for LEA, says lower and lower levels of dissolved oxygen are found in the pond's lower depths in August and September. No suitable habitat for salmon is found during this time because algae thrive on phosphorus. Bacteria essentially feed on the dead algae using up the pond's oxygen supply in the process.

"The survey is intended as a wake-up call to those within the watershed," Holme said. "Hopefully private landowners can fix some areas, while towns can concentrate on others."

The fact Moose Pond already has a working lake association helped greatly in it being selected for the erosion survey. "You do need a working association to qualify for any grants," said Holme. "Agencies like to know the work being described in a grant application can actually be carried out."

The survey begins with a training session at 9 a.m. at the Knight's Hill Association Meeting Hall on Moose Pond Drive in Bridgton. The public is welcome. Armed with cameras and GPS devices, surveyors will spend the afternoon in the field. The survey is rain or shine.
