See the red-brown tags on the map for the low flow details.
Drought Map from USGS 7-day average streamflows compared to historic averages
In Region 1, Caddo Parish enters the New Year free of a drought rating. West Bossier Parish has been untouched by drought for many weeks, falls into a below normal rating to kick off the new calendar year. A section of Region 2 watershed clears off the drought map Monday, leaving Jackson, Winn and Caldwell Parishes without a rating.
In Region 7, the Pearl River watershed east Washington and St Tammany Parish are stepped down from moderate drought to below normal rating over the weekend. Tangipahoa River channel through Tangipahoa Parish has escalated from severe to extreme drought. All remaining surface area of watershed regions 6, 7 and 8 remain clear of the drought map, unrated.
Extreme drought remains locked on central Morehouse in watershed Region 3 Monday. Severe drought rating still applies to east Morehouse, Richland and Franklin Parishes with the immediate area around the Tensas River stepped up from below normal to moderate drought, shifting to extreme drought from the Tensas River immediate channel to the east state line, Mississippi River.
An area of moderate drought holds on to Bayou Pierre channel into the new year. Watershed Region 2 remains in moderate drought through Grant and LaSalle Parishes. Watersheds Region 4 and 5 persist in severe drought in all but Evangeline and Acadia Parishes, which have improved over the weekend from moderate drought to below normal.
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 Sunday December 31 is clear, taken at a low wind speed 2.1 mph. The appearance of HABS in this image is considered reliable, as the wind is not mixing and submerging the bloom.
Lake Pontchartrain and Lake Maurepas appear clear of HAB activity. Lake Verret is clearly seen in this image with two large localized HABs off the west shore at 600 to 700 thousand cells per 100 ml. Lake Palourde has a HAB in the southwest appearing at similar concentration to the Lake Verret bloom. An area of dispersed HABs appear at midlake on Lake Palourde, similar concentration. Lac des Allemands, Bayou Fortier share an area of HABs, open water bloom below 500 thousand cells per 100 ml. Lake Cataouache and Lake Salvador appear free of HAB. Lake Lery widespread HAB extends from north shore to south shore for the middle section of the lake at 600 thousand cells per 100 ml. Check back daily for our interpretation of the latest satellite image of the southeast water bodies.
Note about hazardous spill incident reporting, from LDEQ: Information contained in the Field Interview form is the preliminary observation of the inspector. This should not be construed as a final determination of LDEQ, its officers or personnel as to any matter, including compliance or non-compliance with statutes, regulations and permits.
Each day of non-compliance is considered a separate violation of the Louisiana Environmental Quality Act.
See the pink tags on the map with the watershed layer turned on, showing the potential impact zone of hazardous spills in the environment. Refer to the Spills button on the right of the map for more incident reports filed this year.
