SUMMARY OF VOLUNTEER SURVEY WATER QUALITY----------------------------------------------------------------------- Overall water quality was excellent. The worst problems were reported as: 1. decaying vegetation 2. high water levels Sources of actual or potential problems includes: EXCESSIVE GEESE. DEVELKPMENT OF BRIGGS FARM INTO RESIDENTIAL AREA. Were there days (and how many) when poor water quality impaired Fishing - NO(0) Swimming - NO(0) Aesthetics - NO(0) MANAGEMENT-------------------------------------------------------------------------- Did the lake receive chemical treatments this year? NO Were fish stocked this year? YES Any lake groups present (such as a lake association)? NO Any lake management activities this year? NO OTHER------------------------------------------------------------------------------- How many homes/new homes are there on the lake shore? 43 Changes since last year? NONE. Lake Uses and Facilities at the lake include: swimming fishing Motor boat restrictions include: 5 mph speed restriction.
FIELD OBSERVATIONS OF ECOLOGY STAFF 6-2-97 Highest water level since 1946, so high that macrophytes aren't observed. There has been a lack of mallards and widgeons and also fewer geese this winter. There was a pair of loons spotted this winter.
TROPHIC STATUS Estimated Trophic State: Oligotrophic Mean Trophic State Index (Secchi): 37 (Oligotrophic) Mean Trophic State Index (Total Phosphorus): 0 (Not assessed) Mean Trophic State Index (Chlorophyll a): 0 (Not assessed)
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Ward Lake is an oligotrophic lake with depleted DO concentrations in the hypolimnion. Because the water is tannin in coloration, it is assumed that some or most of the oxygen demand in the hypolimnion is chemical in nature and not necessarily biological. All TSI values support an oligotrophic assessment. TSI values for chlorophyll and total phosphorus were supplied by Thurston County Environmental Health as were the DO profiles.
COMMENTS FROM 98/07/06 AQUATIC PLANT SURVEY partly cloudy, light breeze, bullfrogs, sparse plant cover - mostly Nymphaea. Shoreline drops steeply in most areas, plant community pretty homogeneous. Conducted habitat survey for Dave Hallock. Maximum depth of plant growth: 6.0M.
AQUATIC PLANT LIST (This list may be from multiple years and sources.) Callitriche sp. (water-starwort) Callitriche stagnalis (pond water-starwort) Iris pseudacorus (yellow flag) Juncus sp. or Eleocharis sp. (small grass-like plants) Nitella sp. (stonewort) Nuphar polysepala (spatter-dock, yellow water-lily) Nymphaea odorata (fragrant waterlily) Scirpus sp. (bulrush) Typha sp. (cat-tail) Utricularia sp. (bladderwort)
