Volunteer

Lake Pontchartrain Basin Foundation's success depends on the dedication and talents of thousands of volunteers. People often volunteer with us because they feel a personal commitment to protecting and restoring our basin, so that all of us can enjoy it. Motivated by this valuable feeling of ownership, volunteers get involved in a variety of fun, interesting events that we hold throughout the year. Learn more

Many of these events are annual, including our Back to the Beach Festival, Beach Sweep, Fishing Rodeo, Golf Classic, and Northshore "Let's Make Waves" Party.

Lake Pontchartrain Basin Foundation staff also welcomes those who wish to volunteer in our office. Office volunteers regularly offer their time and talents throughout the year. Their assistance is invaluable. Learn more

Weekly Report

Weekly Report

The Lake Pontchartrain Basin Foundation began EPA approved intensive water quality monitoring in August 2000, in an effort to educate the public about water quality and to lend evidence for the retraction of swimming advisories along the shore of Lake Pontchartrain. As of 2006, Lake Pontchartrain was removed from Louisiana DEQ's Impaired Water Bodies list except for a sliver along the south shore which is still under review.

Ten historically recreational sites are sampled on a weekly basis and another ten sites of interest are sampled on a monthly basis. Several water quality parameters, including fecal coliform bacteria levels, are tested. (Fecal coliform levels below 200 indicate the water is safe for swimming.) The weekly sites are tested every Tuesday morning for data to be disseminated on Fridays (due to bacteria analysis- a process that takes 48 hours). Please be aware that rainfall causes spikes in bacteria counts. You can find more information on the site locations by visiting our map tour.

Rainfall Runoff Warnings

The Lake's water quality is directly related to rainfall runoff.
If it has rained in your area in the past 3 days, the runoff could pollute the Lake.
