St. Louis ponds were created by the construction of I-5, these ponds were dug out for gravel needed for the freeway nearby. They began to fill in with water, and over time became this neat park that has half a dozen different kinds of fish to try to catch, One of which is stocked yearly with rainbow trout. (pond #3) It is managed by ODFW. There are many wheelchair accessable fishing platforms, and other areas to get close to the water. This park is open dawn to dusk, but the gate to the main park is closed from Oct. 1st. to March 1st. However you are permited to park along the road and easily walk in.It is not a long walk at all.( Not wheel chair accessable durning these months.)
I am amazed at how folks can just leave thier garbage behind while enjoying a wonderful area like this. Simply pack it out to one of the many garbage cans, and a large dumpster provided here in the park. If you intend to search for this hide, perhaps bring a shopping bag to CITO to show the world you care, and are willing to do so with your actions. I try to keep a few bags in my geoback pack for this reason.
Your are looking for a nice large 1/2 gallon plastic screw top hidden well, It has some natrual camo on top, please replace once found.
