demonstrated that Deer Creek provided a coldwater fishery from the 1920s through the 1960s. In 1990,
the MDNR, Surface Water Quality Division collected 48 fish from Deer, Warner, Collins, and Eaton
creeks, including brown trout, brook trout, bluntnose minnow, blacknose dace, brook stickleback,
creek chub, mottled sculpin, rock bass, and common white sucker (Anonymous 1992). Although creel
survey data are not available for Patricia Lake, anglers report that trout and coolwater species are
present in the impoundment. Below the impoundment, Deer Creek produces opportunities for anglers
to catch steelhead in the spring and salmon in the fall, though the impoundment warms the water
during the summer, allowing the presence of warmwater species. Deer Creek below the impoundment
is also a large producer of sea lampreys, with a predicted annual production of 3,633 transformers (E.
Koon, United States Fish and Wildlife Service, personal communication). In 2002, 111 adult sea
lampreys were collected in traps below the dam and the estimated number of adult sea lampreys in
Deer Creek was 313. In addition to the trapping, the USFWS chemically treats the lower section of
Deer Creek to eradicate sea lamprey ammocoetes.
Patricia Lake was surveyed using electrofishing gear in 2006 by the MDNR (Kalish 2007a). The fish
community was dominated by white suckers, with yellow perch, bluegill, largemouth bass, rock bass,
brown and black bullheads, and northern pike also present in relatively low abundance. Kalish (2007a)
described the fish community as having low age-class diversity, low overall abundance, and limited
species richness. He recommended discussing the feasibility of dam disposition or modification
options with the owner and Jordan River watershed stakeholders, but did not recommend stocking
coolwater fish due to the potential negative effects on coldwater populations, and did not recommend
stocking coldwater fish due to the potential negative genetic effects that hatchery fish may have on
naturalized populations.
Current Status
The August 2009 survey of Deer Creek was the first survey since 1990. The survey included the 800-ft
section upstream from Bergman Road, which is approximately half-way between Deer Lake and
Patricia Lake. Sampling gear consisted of a two-probe, manually-propelled electrofishing boat, and a
four-person crew. The survey followed standardized Status and Trends protocols established by the
MDNRE Fisheries Division (Wills et al. 2008), and electrofishing efficiency was characterized as
satisfactory. Riparian vegetation consisted mainly of tag alder, with various coniferous trees such as
white cedar, tamarack, and black spruce. Aquatic vegetation consisted mainly of Valisneria and
watercress. Water clarity was excellent throughout the station. There was a moderate amount of
submerged woody debris, and there was some evidence of historic logging since a few large logs were
embedded in the stream substrate. Undercut banks were scarce in the survey section. Average stream
width was 29 feet, average depth was 1.5 feet, and discharge was 24 cubic feet per second. The bottom
substrate was 90% sand and 10% silt. Although the survey section was characterized as run habitat,
there were some pools present associated with woody debris. A temperature logger was placed in Deer
Creek in 2005, which recorded hourly stream temperatures from May 17 to October 20 at Pearsall
Road, which is approximately 3 miles downstream of Bergman Road. Average monthly water
temperature varied from a low of 53.0°F in October to a high of 64.4°F in July (Table 1). Monthly
maximum water temperature exceeded 70°F in June (73.2°F), July (72.4°F), and August (71.9°F), but
it generally only exceeded 70°F for 6 to 7 hours during a few days of each month. The longest period
during which water temperature exceeded 70°F was 8 hours on August 2, and the maximum daily
temperature exceeded 70°F for only 21 of the 92 days from June through August. Raleigh (1982)
