Streamflow Situation from USGS real time streamflow monitoring stations around the eight watersheds of the state

Drought Map from USGS 7-day average streamflows compared to historic averages
Region 4 Calcasieu River channel steps up to extreme drought over the weekend while Tensas and Tangipahoa River watersheds step down from extreme to severe drought in Region 3 and Region 7, respectively. The Pearl River watershed remains in severe drought Monday, along with a section of north central Morehouse Parish in region 3.
Severe drought has come off the Region 1 Saline Bayou channel and Region 2 Grant and LaSalle Parishes, leaving all area of Regions 1 and 2 below normal after the weekend. In Region 3 Morehouse, Richland and Franklin Parishes are rated moderate drought with the area from Tensas River to Mississippi River at severe drought. Heading south to the Gulf Coast, Region 4 is a mixture of below normal to extreme, Region 5 moderate drought in all but Evangeline and Acadia Parishes, Monday rated below normal.
Watershed regions 6 and 8 are clear of the drought map Monday. Wind advisory and flash flood watch apply to Regions 6, 7 and 8 Monday and Tuesday.
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 7 is partially cloud obscured, taken at a wind speed 6.8 mph. This image shows extensive HAB activity in Lake Pontchartrain, 100 thousand cells per 100 ml. Lake Maurepas appears HAB free. Lake Verret, Lake Palourde, Lac des Allemands and Bayou Fortier are completely cloud obscured in this image taken Sunday. Lake Cataouache is cloud obscured, Lake Salvador is cloud blocked in the north, clear in the south. Lake Lery presents with lakewide bloom 500 thousand cells per 100 ml.

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.
