West Wetlands
West Wetlands is a nice decent size park complex with play areas, picnic areas, and at the east end there is a fishing pond. It also provides one of the few improved boat launches on the lower river (Morelos Division) with boat trailer parking near the ramp.
If you launch into the river at West Wetlands I suggest you use a shallow water boat, but in the rare times of high water who knows. The pond in the park is managed for fishing and is often utilized for organized kids fishing clinics.
