Salmon River area is great!
An option is the campground next to North Fork Reservoir (just east of Estacada) since you're in Gladstone where, if your kids are under 17 can fish the pond (Small Fry Lake) there.
You won't be able to fish Small Fry but the kids can and a stones throw away is the reservoir where all can fish.
Promontory Park Campground
If you want to teach your children to fish, Promontory Park is the place to come. Small Fry Lake, a one-acre lake within the park, was developed for the exclusive use of young anglers. Kids up to 17 years old can fish for their limit of two fish per day on Small Fry Lake. Anglers of all ages can fish on the 350-acre North Fork Reservoir. In addition to fishing, Promontory Park has:
- 50 campsites, including 13 yomes
- Restrooms and showers
- Picnic areas
- Picnic shelter accommodating 75 people
- Electric cooking facilities
Groceries, ice, cafe, fishing tackle, moorage and boat rentals are available at the concession store located at the downstream end of the park. A boat dock and launching area are next to the store.
For people with disabilities, the park has accessible restrooms, campsites and fishing areas.
Another possibility is Harriet lake:
This 22-acre reservoir, which stores water for PGE’s Oak Grove Hydroelectric Project, is stocked with trout.
A small, 10-site campground is located at the head of the lake.
For people with disabilities, the park has accessible restrooms and picnic sites.
