#1 could be LCK jetty but frankly you can't even see much and it's such an old picture, how the jetty looks today is different. Anyways do take note that there is Coast Guard facility nearby IIRC and I hear that they can be quite prickly about shooting that facility but if you just concentrate on the jetty it should be alright.
For #2, that's most probably Lower Peirce Reservoir. There are loads of such installations here and there, including at MacRitchie Reservoir but the positioning of the treeline makes me think that this is LP.
You are asking because you want to shoot the thing or?
