Lower Latham Reservoir - Weld County
Ownership: None Listed
Description: Lower Latham would undoubtedly be one of Colorado's finest birding reservoirs if it could just be adequately scanned from the road. Alas, all views of the water in the lake are distant. The best views are from the road along CR 47 looking west. Thus, best viewing is in the morning. Sometimes, on windless days with few heatwaves, nearly the entire reservoir can be observed with a good telescope. Lower Latham is, however, better known for the small marshy ponds along CR 48 just south of the reservoir. These are some of the finest roadside marshes in the state, a reliable location for Virginia Rail, Sora, Marsh Wren, and blackbirds including Great-tailed Grackle. Occasionally, American Bitterns are found here, and in many winters, Short-eared Owls can be found at dusk. In migration the wet fields and canals along this road can fill up with herons, egrets and ibis, making this one of the better places to look for rarities like Glossy Ibis; Little Blue and Tricolored Herons have also been found here. When water levels are right, the shorebirding can be quite good.
Habitat: Pond/Lake/Reservoir, Wet Meadow, Marsh
Directions: To get to Lower Latham from I-76 or US 34, you will have to find CR 49, which can be reached from the south by taking exit 34 off I-76, or from the north from US 34, 5.5 miles east of the US 34/85 intersection. Take CR 49 to CR 48 (16 miles north of I-76, and 4 miles south of US-34), and turn west. To get to Lower Latham from US 85, turn east on CR 44 near the "town" of Peckham and go five miles east to CR 43, then two miles north to CR 48 on the right (east). The section of CR 48 between CRs 43 and 47 contains the cattail marshes. CR 47 allows the scanning of the reservoir from the east.
