The Ogden through town offers some easier sections that are good for learning at low to medium flows.
A very short section with an official-looking putin would be below Grant Ave, to the 'Crystal' wave below Wall Ave, by the Walmart. There are many possible putins, the furthest upstream that is still class 2 would be at the botanical garden above Monroe Ave. There is a popular surf wave under the Gramercy street bridge. Beware of fishhooks in the bushes along this run.
At 550 cfs, the Lincoln bridge has two feet of clearance.
If the level is over 520 cfs on the
Ogden near Gibson USGS gauge, and Lincoln Ave is a portage, another short section that is generally still a good intro would be below Lincoln to Crystal wave. There is a gravel turnout for parking on the south side of the river at Lincoln.
Crystal wave is normally the end of this section. You could float another couple hundred yards, but you would need to pack your boat back to the Walmart lot, as driving is no longer allowed along the river in that area. Often there is riverwide wood a few hundred yards below the Crystal wave, on the third railroad bridge. Bank scouting is recommended before paddling below there; as there is a lot of wood. The 'car drop' is behind the 21st street pond, then some brushy meanders with sweepers lead to the confluence with the Weber. In 2022 there was a multitrunk riverwide log jam, a couple hundred hards above the confluence, easily visible from the bike path. If you paddle below the confluence, be aware of the large diversion dam .4 miles below the confluence, and scout your takeout along 17th south and 1200W.
