SUMMARY OF VOLUNTEER SURVEY WATER QUALITY----------------------------------------------------------------------- Overall water quality was poor. The worst problems were reported as: 1. declining long-term trend 2. suspended sediment 3. algae Sources of actual or potential problems includes: ANNUAL WASTE AND RECYCLING IN THE LAKE ITSELF - PLANT DECAY Were there days (and how many) when poor water quality impaired Fishing - NO(0) Swimming - YES(365) Aesthetics - YES(60) MANAGEMENT-------------------------------------------------------------------------- Did the lake receive chemical treatments this year? NO Were fish stocked this year? NO Any lake groups present (such as a lake association)? YES Any lake management activities this year? YES OTHER------------------------------------------------------------------------------- How many homes/new homes are there on the lake shore?~ 25 TO 30 Changes since last year?
FIELD OBSERVATIONS OF ECOLOGY STAFF 5-29-97 A horrific blue-green algal bloom observed. The lake is reportedly a good brown trout and bass fishery. Very few zooplanton observed in the water samples. 9-2-97 There is a heavy H2S odor in the hypolimnion samples. Duplicate site straight out from launch. Duplicate coordinates = 45 36.813N; 122 25.333W.
TROPHIC STATUS Estimated Trophic State: Eutrophic Mean Trophic State Index (Secchi): 50 (Meso-eutrophic) Mean Trophic State Index (Total Phosphorus): 54 (Eutrophic) Mean Trophic State Index (Chlorophyll a): 62 (Eutrophic)
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Lacamas Lake is an eutrophic lake rich in nutrients, aquatic macrophytes and algae. All TSI indicators support the eutrophic assessment.
COMMENTS FROM 97/09/03 AQUATIC PLANT SURVEY Partly cloudy, calm. Met to 'map' aquatic plants in the lake. Dominant plant was a P. amplifolius hybrid. E. canadensis and Egeria densa present in some dense patches, and dominant in some areas, but not throughout the lake. Bryozoans, otters, waterfowl. Most of shoreline with natural vegetation. Water very green. Maximum depth of plant growth: 4.5M.
AQUATIC PLANT LIST (This list may be from multiple years and sources.) Brasenia schreberi (watershield) Ceratophyllum demersum (Coontail; hornwort) Egeria densa (Brazilian elodea) Elodea canadensis (common elodea) Juncus sp. or Eleocharis sp. (small grass-like plants) Najas flexilis (common naiad) Nuphar lutea (yellow water-lily) Nuphar polysepala (spatter-dock, yellow water-lily) Potamogeton amplifolius (large-leaf pondweed) Potamogeton natans (floating leaf pondweed) Potamogeton robbinsii (fern leaf pondweed) Potamogeton sp (thin leaved) (thin leaved pondweed) Scirpus sp. (bulrush) Sparganium angustifolium (narrowleaf bur-reed)
