Thanks for setting it up, Clare. I had fun doing it and challenging my analysis skills on the trickier ones.

@smittyo: What do believe were the keys to getting the 3 bridge locations correct?

tRicky:
Bizarrely I thought it was 2 & 3 I might get reversed but turned out to be 3 & 7. It was most likely the proliferation of thick stuff at the far end of the bridges you had to look out for.

Yeah it's a matter of what you see in the distance beyond the bridges. On 2 you can see the open hill. On 7 you can see some open area but no hill. On 3 all you see is green.

I did ok putting photos and control circles together but the difficulty came in after that. Sometimes I couldn't find the egg and sometimes I couldn't be sure what color it was. My daughter was a big help with that. I still managed to make a clerical error on one of the easiest ones. I don't think I have any actual trouble distinguishing yellow from blue.

@GuyO - What fossil said. It's primarily about figuring out how the area on the far side of the bridge should look. I actually had a fourth bridge picture, but it got tossed because it would be too difficult to tell between that picture and number 2 - they both had hills in the background. I had one person mention looking at the direction of the shadows. That should make it easy to separate number 2 from 3 and 7. Of course, you would have to trust that the pictures were taken within a similar time span (they were).

GuyO:
To figure out 2 (H), I used the view beyond the bridge, as well as noting the rocky riverbed, while the others only had vegetation visible below the bridges.

I should have looked beyond the bridges for 3 & 7. Instead, I settled on 7 being R based on there being a fence running north from the bridge, and the pic showing only the right-side railing continuing.

Then again, the railings visible on H (2) were identical to R (7), and they continued on both sides on N (3), while neither had adjoining fencing on the map, at the control. :-/

Q: Where does the water entering the lake come from?

tRicky:
Guy, pretty sure I made a similar error - I noted the continuing railing for R so assigned it to 7 then just tried to distinguish between the other two bridges, one of which was already going to be incorrect since I now had 7 wrong!

I think the railing on all the fences is the same and the pictures are all framed so that you are too close in to see the fence connect at number 7.

According to this page: https://www.laparks.org/aquatic/balboa/water-quali...
the water is "reclaimed from domestic use." It flows in at the small cascades (picture E) from some sort of underground system and then flows out through the stream at the SE corner (Picture C).

GuyO:
I thought it might have been diverted from the river that flowed under those bridges (into an underground conduit).

What the webpage is saying is that the lake water comes directly from one or more sewage treatment plants. I'm hoping that the treatment is sufficient that the lake has no noticeable odor. Couldn't help but notice that all contact with the water is prohibited.

It's a nice lake. I've never noticed a smell. Sometimes the water coming out of the cascades looks kind of colored. It runs straight into the LA River.
