I have not heard of Heater; and I have never seen it on any maps. It is also NOT listed in either "Fishing in Oregon" nor in "Complete Angler's Guide to Oregon". So, I dunno whut to tell ya.
What species are you after? If it's Crappie, 'gills, bass, cats etc. - you might want to try the lakes/ponds in Lyons. Six blocks east of Main & Hwy. 226, turn left (north) onto 13th St. Go about 3 blocks north (heading towards John Neal Park on the N. Santiam). You can't miss the ponds on the left.
I've not fished there. But, it looks good. You can probably put in a tube or toon, if you want.
BTW, sitting in your back yard like you are in your avatar tell us that you have SERIOUS addiction! We'll look for a support group in your area!!!
