Boil Water Advisories:
Kinder has issued a system-wide BWA following repairs to water lines yesterday. Customers will be advised when potable water tests come back clear of any contamination that may have entered the lines during the work.
Alexandria issued a precautionary boil water advisory for customers on Detroit Street after repairs to a 6-inch water main Monday.
City of Ruston BWA issued Monday for possible microbiological contamination will remain in effect until lab tests confirm safety.
Oberlin has issued a BWA due to a loss of water pressure from repairs being made to water lines Monday.

Drought Map from USGS 7-day average streamflows compared to historic averages
Drought continues to release all over the state Wednesday as streamflows picked up to seasonal normal in the northwest, to much above normal in the northeast with high levels and flooding in Region 7.
The drought map has shifted considerably overnight, extreme and severe drought giving way to below normal ratings in most cases. The Calcasieu River channel through Region 4 has downshifted from extreme drought to severe today, the last area holding a severe drought rating. A strip of moderate drought continues to squeeze the Sabine River at the west Louisiana border, and moderate drought appears along the Pearl River watershed in Region 7, taking the east half of Washington Parish and the east edge of St Tammany.
Area rated below normal Wednesday includes parts of watershed Regions 1, 3, 4 and 5. Tangipahoa Parish in Region 7 is still rated below normal, stepped down from severe drought yesterday.
Watershed regions 6 and 8 are clear of the drought map.
Note WaterToday reports day-to-day changes recorded by USGS streamflow monitors on rivers and tributaries located in Louisiana, along with monitors upstream in the Mississippi River basin: Ohio, Georgia and southwest New York state. USGS creates a drought map from 7-day average streamflow readings, by comparing the average with the historic weekly normal flow value for each location. The drought ratings are below normal, moderate hydrologic drought, severe drought and extreme drought.
HABs Report from National Centers for Coastal Ocean Science (NCCOS) satellite monitoring program
NCCOS image captured Jan 8 is mostly cloud obscured, taken at a low wind speed 2.9 mph. No HABs are detected in the very limited view of Lake Pontchartrain. All other water bodies are completely cloud obscured. The previous image was captured January 7 at a slightly higher wind speed, over 6 mph, showing extensive HAB activity in Lake Pontchartrain. Lake Maurepas appeared in the Jan 7 image HAB free. Lake Verret, Lake Palourde, Lac des Allemands and Bayou Fortier were completely cloud obscured Jan 7 as they are also obscured Jan 8 image. On Jan 7, Lake Cataouache was cloud obscured, Lake Salvador is cloud blocked in the north, clear in the south. Lake Lery presented Jan 7 with lakewide bloom 500 thousand cells per 100 ml, Lake Lery is totally cloud obscured in the image we are looking at today. Check back daily for an interpretation of the latest satellite image of the southeast water bodies.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
