Streamflow Situation from USGS real time streamflow monitoring stations around the eight watersheds of the state
Much below normal flows continue Tuesday with extreme low flows registering at two stations on the Sabine River and a tributary of Calcasieu River in watershed Region 4, with one station registering an extreme low flow in Region 3 Tuesday.
Drought Map from USGS 7-day average streamflows compared to historic averages
The drought map appears much the same as yesterday with an expansion of below normal rated area in Region 1, Bossier Parish in the northwest shows up on the drought map Tuesday, joining the Bayou Pierre channel DeSoto, Sabine and part of Natchitoches Parishes at below normal. Region 2 Grant and Winn Parishes remain below normal Tuesday while Region 3 surface area remains clear of a rating on the drought map for now. With the present trend and no additional precipitation expected over the next 36 hours, part of Region 3 may return to the drought map later in the week as the seven-day streamflow average drops in keeping with the extreme low streamflow recorded this morning.
The highest rating remains moderate drought along the Calcasieu River channel in Region 4. Below normal ratings hang on to most of Regions 4 and 5 Tuesday, except Evangeline and Acadia Parish, not rated. Regions 6, 7 and 8 in the east state area remain clear of the drought map again today.
See the Flood button to the right of the map for more information on streamflows. Red-brown tags on the map refer to extreme low flows.
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 15 is partially cloud obscured, taken at a wind speed 5.6 mph. No HABs activity detected in Irish Bayou, Lake Pontchartrain, Lake Maurepas, Lake Verret, Lake Palourde, Catouache or Salvador. Lake Lery and Black Bay inland water bodies appear with lakewide HABs at a lower high concentration than the previous capture from Jan 14, dropping from high concentration 500 thousand cells per 100 ml to 200 thousand cells per 100 ml.
