Transect Data | Water Data

   Maltby Lake #1 is one of three small reservoirs owned by the South Central Connecticut Regional Water Authority in West Haven. It has an area of 19 acres and a maximum depth of 21 feet. Conifers line most of the shore, and Route 34 borders the lake to the south. The lake is open for fishing by special permit, but boats are not allowed. 

   Aquatic plants were abundant in parts of Maltby Lake #1 during a 2004 survey and absent from other areas. Variable pondweed (Potamogeton gramineus) and thread-leaf naiad (Najas gracillima) were the most abundant submerged species, with variable pondweed limited to water less than 9 feet deep, and thread-leaf naiad extending into deeper areas.

   Species richness was low. Only two other aquatic species were recorded. Leafy pondweed (Potamogeton foliosus) was found growing with thread-leaf naiad in a large patch in the middle of the lake, where the water was 12 feet deep, and spikerush (Eleocharis species) was found in a small patch in shallow water at the west end of the lake.
