Lake of the Woods is a large natural lake nestled in the southern Oregon Cascades within sight of the sleeping Mount McLaughlin. With easy access right off Hwy 140 and at almost 5000 feet elevation, it’s a popular summer retreat for hordes of campers, boaters, hikers, and day users of all sorts—a recipe which usually keeps me away, but there is a gem of a spot in the middle of it all which is great for odonates.

The gem of a spot is at the easternmost shore of the bay on the eastern side of the lake. That’s Rainbow Bay, and there’s a sedge meadow there which is largely inundated when the lake is at its highest levels during spring and early summer, but becomes mostly dry by late summer and fall. A band of tules hugs the edge of the meadow in deeper water.

This area is easiest to access from dirt pullouts on the side of Dead Indian Road where it passes at its closest. There is also a well-maintained trail that passes through here between the road and the meadow, and connects the Rainbow Bay day use area (to the north) with Sunset Campground (to the south).
This location is well known among Oregon odonatists as the only place in the state where Lance-tipped Darner (Aeshna constricta) can be found somewhat reliably, and I visited on 5 August 2011 in an effort to find nymphs and/or exuviae of that species. I was not successful, but there were plenty of other odonates around to keep me busy.
Things were definitely late up here, as they are all over the Northwest this year. That was most evident in the large number of Spiny Baskettails (Epitheca spinigera) still flying through the open forest around the meadow, and I even found one exuvia of that species still clinging to some vegetation. Normally that species is quite scarce up here by now. Lots of darners were feeding in a loose swarm over the area—three species were represented among the relatively few that I could catch, but the Lance-tipped was not one of them. Clouds of just emerged meadowhawks drifted up from the sedges as I wandered through them.
I haven’t tallied up the complete list of species found at the Rainbow Bay meadow, but below is what I recorded during a few hours on that recent visit. Following that are photos of several of those species taken that day.
