The <br /> existence of a deep central channel— called the low flow channel — allows for boat passage <br /> for all types of river craft at all historical levels.

Site infrastructure, such as restrooms and <br /> parking, is located just upstream from the bridge at Riverside Park. This site would be <br /> located downstream of the existing bridge to avoid affecting the staging, loading, and <br /> unloading of the jet boats that use the area upstream of the bridge. <br /> The passage of jet boats would not be affected by the proposed designs. However, a <br /> possible user conflict should be investigated. Other rivers with similar users, such as the <br /> 6 <br />
