The main campground on the west side of the reservoir, Oasis is a 19-unit campground with 7 overflow sites, covered group pavilions with picnic tables, a group camping area, drinking water, modern restrooms and showers, an RV sewage disposal station, loading docks, and boat launching ramp. Accessible rest rooms, showers, electrical hookups and a campsite are available for campground patrons with special needs. With shrubsteppe and dry hillsides surrounding the campground on 3 sides, and the reservoir on the 4th, the large and numerous deciduous trees creating a riparian area here are definitely a migrant trap. Yuba is seldom visited by birders, but anyone traveling north or south along I-15 in the spring or fall should detour here to look for birds.
Truth be told I have only birded here once--and at the time I mistakenly submitted a checklist for the lake--not the campground because the hot spot did not exist. That being said the habitat is ideal for warblers, and other passerine migrants. YELLOW WARBLER, LAZULI BUNTING, HOUSE FINCH, and BULLOCK'S ORIOLE should be present while the surrounding hill sides usually have LARK and BREWER'S SPARROW, SAGE THRASHER, and plenty of HORNED LARKS. Really just about anything could show up here, and with some coverage the list could probably creep towards 100 species. The reservoir can easily be scoped form here, but I suggest creating a separate checklist using the Yuba Lake SP (incl. Sevier Bridge Reservoir) hot spot since it was created specifically for the whole park. Once there are some more checklists, I will update this to reflect what kind of birds you should see on a typical morning or afternoon here. Birding can easily be done walking the campground roads. The whole campground could be covered in 10 minutes, and with an hour you could thoroughly find all the birds using the area.
