St. Tammany: Trees down, lake rising

As Hurricane Isaac neared southeast Louisiana, the sewer system in one lakefront community in St. Tammany Parish had to be shut down because floodwaters rose over sewage lift stations.

Officials say they believe most people had left Northshore Beach before Tammany Utilities began shutting down the sewage system there.

As bands of rain began crossing the parish Tuesday, calls to the parish's emergency operations center rose. Most were about downed trees.

The government also urged people in low-lying parts of St. Tammany Parish to move vehicles and unsecured property to higher ground.

The National Weather Service also confirms that Lake Pontchartrain was expected to begin rising before dawn and continue to rise through 7 p.m. Wednesday, causing floods that could last from 24 to 36 hours.
