Carter Lake is seeing some late season demands from municipal water users.
During the fall, we typically do our scheduled maintenance on the Colorado-Big Thompson project--of which Carter is a part. In an average year, we see demands drop off in late September/early October, so we shut parts of the project down and do our annual checks. This year, municipal demands are calling for water later than they have in the past. I think this is largely due to the drought. So, Carter is going down at a time of year most of us are used to seeing it start to flatten out.
In December or January, around there somewhere, we'll start pumping water up to Carter again. It typically has its highest water level elevation around May. And then summer starts up again, demands come on, and it starts to go down.
And that's pretty much the cycle.
Let me know if you have other questions, etc. about Carter. Happy to answer what I can.
