Utah, USA
Newton Reservoir is a small, open-country reservoir on Clarkston Creek north of Newton in Cache Valley. A trip here is different from visiting a staffed state park: the federal recreation listing describes primitive facilities, shoreline cottonwoods and willows, and no on-site manager.
Sources reviewed October 8, 2026. This is a planning guide, not a live fishing report, legal regulation digest, or confirmation that a ramp or facility is open today. Dated notices are historical unless explicitly stated otherwise. Check current operator notices and fishing rules before travel. Official source links are non-affiliate links.
The federal directions follow US 91/89 north from Logan to Smithfield, then State Road 218 toward Newton. The reservoir is about two miles north of town. Use the official recreation map to reach the reservoir rather than treating a general waterbody map pin as a trailer ramp or legal shoreline entrance. Recreation.gov lists boat launching, picnicking and primitive camping; it does not provide a live ramp-condition report.
The federal listing describes a reservoir of approximately 290 acres when full, at about 4,770 feet elevation. “When full” matters: that size is not a statement about today’s shoreline or launch depth. The recreation area has no on-site manager. Our planning recommendation is to arrive with drinking water, sun protection and everything needed to remove your rubbish rather than rely on a staffed visitor centre or serviced campground.
Recreation.gov lists June through September as the managed recreation season and describes all-weather access. Those are recurring facility descriptions, not a dated 2027 opening announcement or a guarantee of clear roads, usable ramps or safe ice. For a shoulder-season visit, check conditions before towing a boat. Do not interpret vehicle access or a visible frozen surface as approval to travel onto the reservoir.
The federal recreation summary lists perch, bluegill, sunfish and rainbow trout, but it is not a current stocking report or a complete species survey. Use Utah DWR’s current fishing guidebook and its published revisions to check Newton-specific exceptions, permitted methods and any species-specific harvest rules. In particular, do not infer a tiger-muskie harvest entitlement from a general species listing. Select tackle after confirming the rules for your intended fishery.
