For a second time this week, the swimming area at Lake Mohegan is closed today.

Fairfield health officials, who also closed the lake's beach area Tuesday, decided that runoff from heavy rains a night earlier could cause bacteria levels to rise above the safety standard.

All of the town's beaches on Long Island Sound, however, are open Thursday.

Conditions at Fairfield's beaches is regularly updated at the website, http://fairfieldbeachupdates.blogspot.com/.

Information is also available from the town Health Department at 256-3020 during the work week, and on weekends and holidays by calling the Recreation Department at 256-3144, then selecting option 5, then 3.
