Carlisle Lake is a man-made mill pond located in Onalaska. It no longer receives mill effluent, and has been placed on Ecology's list of shoreline of the state. Carlisle Lake has no surface inlets, and drains to the south fork of the Newkaukum River.

SUMMARY OF VOLUNTEER SURVEY WATER QUALITY----------------------------------------------------------------------- Overall water quality was poor. The worst problems were reported as: 1. algae 2. poor aesthetics 3. declining long-term trend Sources of actual or potential problems includes: FARMS UP STREAM Were there days (and how many) when poor water quality impaired Fishing - NO(0) Swimming - YES(365) Aesthetics - YES(260) 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? 0 Changes since last year? 0 Lake Uses and Facilities at the lake include: fishing The percent of the lakeshore that is sewered: 0 The number of storm drains leading to the lake: N
FIELD OBSERVATIONS OF ECOLOGY STAFF Lots of tadpoles were observed at the public boat launch during the spring field visit. An extremely thick blue-green algal bloom was observed during the summer field visit. The algae was so thick that it sqeezed out of the filter during the chlorophyll filtering process.
TROPHIC STATUS Estimated Trophic State: Eutrophic Mean Trophic State Index (Secchi): 57 (Eutrophic) Mean Trophic State Index (Total Phosphorus): 66 (Eutrophic) Mean Trophic State Index (Chlorophyll a): 67 (Eutrophic)
SUMMARY AND EXPLANATION OF TROPHIC STATE ASSESSMENT Carlisle Lake suffers from substantial nutrient loading which contributes to pronounced algal blooms in the lake. These blooms decrease the water clarity, resulting in the shallow Secchi readings. All characteristics mentioned above are typical of most eutrophic lakes which is the classification of Carlisle Lake.
COMMENTS FROM 97/08/20 AQUATIC PLANT SURVEY Raining! Water brownish in color, reddish sediment at north end. Much reduced plant population compared to past years - the vast majority of rake tosses came up with only organic debris. What plants were present were mostly along the west shore and near the launch. Shoreline with dense cattail / reed canary grass / blackberry community. Maximum depth of plant growth: 1.0M.
AQUATIC PLANT LIST (This list may be from multiple years and sources.) Elodea canadensis (common elodea) Lemna minor (duckweed) Nuphar polysepala (spatter-dock, yellow water-lily) Phalaris arundinacia (reed canarygrass) Potamogeton natans (floating leaf pondweed) Potamogeton sp (thin leaved) (thin leaved pondweed) Typha sp. (cat-tail)
