Swimming restriction
Follow current signs and any closure instructions. The June 2022 city notice warns of swift currents, debris and the dam and states there is no lifeguard. That notice is not today's swimming clearance. Do not jump, dive or approach the dam.

Plan for a river, not a controlled pool
The city lists St. Anthony Sand Bar as a park. It is distinct from St. Anthony Sand Dunes and Egin Lakes. A developed shoreline and swimming equipment in a historical photograph do not guarantee today's water access or conditions.
Read the dated city warning
The June 2022 city newsletter warns about current, debris and the nearby dam and states that no lifeguard is provided. Treat it as dated safety context, not a current opening notice. Stay away from the dam and follow today's signs.
Check before entering the water
Confirm access and advisories with the city at 208-624-3494. No current hours, fees, water-quality clearance or equipment inspection were established. Keep children closely supervised and do not jump or dive.
Use the gallery for orientation
Three reviewed, people-free photos show shoreline steps, a slide structure and dam context. The dam view illustrates a hazard, not a recommended entry. Photos are not current-condition reports, and the retained map point is a recreation-area reference rather than a verified swimming entrance.
Getting There
Locate the city-listed St. Anthony Sand Bar near the southern end of 3rd East and confirm current parking and access with the city. The retained map point is a recreation-area reference, not a verified water-entry location. Use posted access areas, not river structures or the dam.
Quick Navigation
Access Notes
The city currently lists this park by name. Its accessible web page does not establish today's swim conditions, opening hours or equipment operation. The saved shoreline images and historical notice do not replace posted instructions.
Plan Your Visit
Parking & Access
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.
Regulations & Fees
Follow current signs and any closure instructions. The June 2022 city notice warns of swift currents, debris and the dam and states there is no lifeguard. That notice is not today's swimming clearance. Do not jump, dive or approach the dam. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
Seasonality & Flow
Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.
What to Bring
Bring sturdy water shoes to protect your feet on rocks and slippery surfaces. A waterproof dry bag keeps your phone, keys, and valuables safe. Pack a quick-dry towel, sun protection, and drinking water - never drink from the natural water source.
Nearby Facilities
Nearby places from saved public map data, not necessarily facilities at the swimming spot. Confirm access, hours, fees, and amenities with the operator before you drive.
