When submitting eBird observations at Quinsigamond Lake, it is most helpful to start a new checklist for each hotspot around the lake. Use the general hotspot when you have a checklist that includes multiple locations or if no other hotspot or personal location is appropriate for your sightings.

Lake Quinsigamond is a large lake located between Worcester and Shrewsbury. The lake has a length of 4 miles, a depth of up to 85 feet, and a surface area of about 772 acres. The lake is divided into two sections: the northern basin, which is deeper and narrower, and the southern basin, which is shallower and has many islands and coves. Lake Quinsigamond hosts 8 islands with the majority owned by private citizens. Two islands are connected to land via a bridge. The largest island, Drake Island, is state-owned. Water from the lake empties into the Quinsigamond River in the Blackstone Valley.

Quinsigamond State Park consists of two sites. The Regatta Point area offers facilities for swimming, sailing, picnicking, and fishing. The Lake Park area provides a picnic area, swimming beach, and tennis courts.
