Probly 200ft really. If ur looking for big sturgeon godda have a big ass pole so you can Huck it out there as far as possible. That's why I fish here downtown. 50ft hole 10 yards out.
I agree I like to get out of the city as much as I can. I don't have a car to get where I want. There's a 80ft hole by the sellwood bridge but its hard to get to if you don't have a big pole.
Downtown Portland on the moda center side in between the steel and burnside bridge there's a dock that I fish on. U don't need the traditional 10-12 ft pole because its a 40ft hole right under the dock. Go half way down the dock.
