The Louisiana National Guard sent high-water trucks to Crowley and Marksville for evacuations, and says units are on standby statewide.
Staff Sgt. Denis Ricou says the 225th Engineer Brigade in Marksville and the 256th Infantry Brigade Combat Team in Crowley each sent a truck and two soldiers.
He says the guard also brought about 50,000 empty sandbags Thursday to Livingston Parish.
In Crowley, Mayor Greg Jones says residents of about 10 houses asked for help. He estimates that water got into more than 20, mostly in wakes from big trucks driving through flooded streets.
Jones says streets were draining well Thursday afternoon, but some still had a foot of water.
Marksville police say the evacuation there was outside city limits. Avoyelles Parish officials could not be immediately reached for comment.
