Council approves interim fountain to address algae, dissolved-oxygen problems at Heritage Park

Kent council approved an emergency measure authorizing staff to install a temporary fountain at the Heritage Park dam site to address recent pump failures and recurring algae growth that have reduced dissolved oxygen levels in the river area.

Service department staff told council that replacing the existing pumps would cost an estimated $400,000–$500,000 and require extended Main Street closures to move the equipment. As an interim remedy, staff proposed installing a mechanical fountain and contracting with a local pond company for installation and maintenance; staff estimated the fountain cost at roughly $12,000–$15,000.

“Last summer, the pumps quit completely, and so we were unable to get them back up and running,” a presenter said. “In February, when we learned these numbers, I said, I think we need to put the brakes on and maybe take another look.”

Service staff described the fountain design and goals - Fountain height and ring: staff said the fountain would project water roughly 11–12 feet high and create about a 40-foot ring, which they expect will help re-oxygenate the water and limit algae growth. - Cost and procurement: staff estimated installation and initial monitoring at $12,000–$15,000 and proposed working with a local pond company for installation and maintenance. - Interim vs. long-term: the fountain was described as a temporary measure to manage water quality while parks and service staff develop longer-term options for the park and evaluate pump replacement costs and logistics.

Council action and rationale A council member moved to approve the installation with the emergency clause; that motion was seconded and the council voted in favor. Several council members and park liaisons supported the measure as a cost-effective, rapid response that avoids the higher immediate cost and traffic impacts of replacing the pumps.

Public comment and park perspective Council and staff noted the site’s history, including earlier dam removal and subsequent habitat improvements; staff said prior work improved dissolved oxygen and fish habitat overall but that the pumps and pump-house equipment are aging. Parks staff and at least one council member said the fountain preserves water quality while allowing time to study aesthetic and longer-term restoration approaches.

Next steps Staff were authorized to proceed with installation, to monitor dissolved-oxygen effects and algae levels, and to continue analysis of pump replacement options and park enhancements. Staff said they would report back to council on effectiveness and costs.
