The flow of the Rio Grande through Albuquerque and the middle valley will be changing over the next few days.
The Middle Rio Grande Conservancy District has used up its stored supplemental water supply and the river will start dropping through Sunday.
Now, the Middle Rio Grande is made up mostly of pueblo irrigation water as well as water leased by the federal government for the endangered Rio Grande silvery minnow.
Irrigation district spokesman Tom Thorpe says the season is not over yet. He says water will still be diverted for the pueblos and any native flow that might result from rain or runoff can be delivered to other irrigators in the valley.
A persistent drought has left portions of the Rio Grande dry and reservoirs at record low levels.
