Lake: Aurora Reservoir

CAUTION:AURORA IS GETTING FILLED

Post By: Hawaiian Punch      Posted: 2/9/2020 9:34:12 AM     Points: 7195    
I just talked to the powers to be at Aurora and was told the repairs are done and water is being pumped to catch up and bring the level to its normal pool.
Great news!
Now . . . . .get smart!!!!!!!!!!!!!!!!!!!!!!
The edge is going to be shaky and or soft as the lake fills that edge will be changing and may or may not be safe at any given time . . . .the park office says the ice at the back of the coves is 3 inchs and up . . .main lake is still open!
Please do not give me a reason to say "I told you so"
I'm butt hurt because I really love to ice fish Aurora,but I'm just not into getting a dunking.

Good advice H-P, better be safe than sorry. It would be great if Aurora would post some signs giving the information about the lake level rising to try and avoid disaster.

BYOB . . . .bring your own board!

Thanks for the info HP, I'm not sure what I'm going to do! I've gone through ice once in my life and I don't ever wanna go through that again!

Coloradocity . . . . .I'd try the marina cove,its location in where the south shore is at the bottom of a hill makes for a shaded shoreline . . .I have gotten on and off on the south side of the marina cove when the north side was 2 ft of open water.The north shore has no protection from the sun and will open when theres sunshine.Take a spud bar and test the edges . . . .just because there are people on the ice don't make it safe!

Walk out on the ice wearing a belly boat--and keep it on all day. Word up!!

Here is a really good question.If the water at Aurora comes in a underground pipeline,you would think it is buried below the frost line. Here is my question,is there thermal transfer of ground warmth to that water?
This is what happens when I got nothing to do . . . .
If there is thermal transfer,how much warmer is the water and how does that change the ice or lack of ice?
Add the draw down/refill and lake depth to this and you got a mind twister.
I look forward to all you brainyacts replys.

Heat flows from hot to cold. So yes if the ground temperature is warmer than the water some heat transfer will occur. How much change would require actual temperatures taken at the upper end verses the lower end where it flows into the reservoir. You are also dealing with a dynamic median in that the water is constantly moving. Water has varying density(specific gravity) depending on temperature and air pressure so the amount coming in verses the over all capacity of the lake would determine what effect it would have on the temperature of the reservoir and the ice on it. IMO, I am not brainyac but I have done some material testing.

Not too old to fish . . .that's some good info.I don't have any way to get temps before and after,but its got to warm the water a bit (although its got to be pretty cold when it gets pumped down from the hills) still think there is enough heat picked up to make a difference.

So how do we know when filling is complete? With the cold temps these last few days I was hoping to get on the ice this weekend but donít wanna push my luck

nickab . . . .the lake was around 10 feet down,that equals a lot of water.Yes we have had plenty of cold weather to make ice and you will be able to get on the ice (find a shaded spot) but here's a few things to know.The snow equals weight on top of ice,weight equals slush,slush equals unknown ice conditions.I have talked to several people that have been out at Aurora and every one of them reported it to be just that . . . . .snow over slush,slush over ice . . .main lake covered but not safe in any way shape or form.You want to go,bring your knee high rubber boots and all the ice rescue stuff.
You want to know when the lake is full? Go have a look at the boat ramp or any of the beach/shore lines . . .best way? look at the cattail beds or areas of rip rap rock cover . . .you can read the water line.
