Answer
Rocky, you have collected Caltha palustris (marsh-marigold). If these were indeed a species of St. John's wort, the leaves would have been opposite one another and entire along the margin (note these are alternate and toothed), among other differences. Caltha palustris is a native, spring-flowering species of wetlands and shorelines.
