Washington Park Lake is a body of water in Albany, New York located in the southwestern corner of Washington Park. It has a surface area of 5.2acres and a mean depth of 6.6feet. The deepest sections of the lake are just over 11feet deep.[1] The lake is roughly 1600feet long and 140feet wide. [2] [3] Next to the lake is the Washington Park Lakehouse and an amphitheater where the Park Playhouse performs musicals in the summer. A wrought-iron pedestrian bridge spans the lake at its narrowest point. The footbridge over Washington Park Lake is the only remaining original structure in Washington Park. Erected over the lake in 1875 the lamps on the bridge were originally gas burning but were electrified in 1881.[4] Ice skating is permitted on Washington Park Lake, though swimming is prohibited.[5]
In 1986 after years of the lake being two to three feet below its normal depth the city repaired cracks and leaks in a concrete spillway.[6] After the lake continued to be approximately one foot below normal level, the next year another leak was found where a 70adj=midNaNadj=mid beech tree had grown on top of a 19th-century brick sewer pipe that was along the southern shore of the lake. The break in the 5adj=midNaNadj=mid sewer pipe created a sinkhole that allowed water from the lake to flow into the sewer.[7] The same pipe caused more problems in 1995 and more repairs occurred.[8]
In 1991 two days after copper sulfate was applied to the lake to kill algae a fish kill occurred due to a lack of oxygen in the water. Hundreds of fish died with many experiencing hypoxic conditions near the surface. The city hooked up a 200feet pipe to two compressors that pumped oxygen into the lake similar to an aerator in an aquarium. This raised oxygen levels quickly and fish returned to their normal behavior.[9]
