They have been releasing water to keep other reservoirs at a higher level. The Colorado river has many reservoirs. There is enough water in the reservoirs for 2 years without any rain. A couple of wet years and the reservoirs can be filled again.
Not entirely sure but there has been a lot of wind in the area from what I've seen watching videos on the water level. Could be a factor of wind erosion, water erosion, drought, etc.
Is it just not raining anymore there? Drought? What has happened to Lake Meade?

a cooling atmosphere holds less water than a warm one.
