I don't think Sedillo Hill has any kind of lake, pond or reservoir. Maybe a couple of cattle tanks. Says Mike Bilbo
Why not camp at Water Canyon Campground since you're here at Sedillo Hill Reservoir. If you need a spot to stay Days Inn Socorro is a fine choice. Camping is available at The Box, and after a long day outdoors Rodeway Inn Socorro is a great place to spend a night or two. High temperatures at Sedillo Hill Reservoir during the summertime
are in the 80's while night lows are typically in the 50's. The wintertime brings highs down to the 40's with winter lows in the 10's overnight here at Sedillo Hill Reservoir.
