Historical Description

Source:1980, Surface Water Resources of Green County,WI:WI-DNR Lake Montesian, T3N, R8E, S7 Surface Acres = 7.0, S.D.F. = 2.16, Maximum Depth = 15 feet This small man-made lake lies entirely within a park on the west side of Monticello. In 1966, the Village completed lake construction at an old mill pond site. It is triangular with an island in the center, accessible by a foot bridge. Springs and an artesian well feed the lake and an overflow runs to the West Branch of the Little Sugar River. The water is very clear in spite of a muck bottom. Aquatic vegetation includes pondweeds, coontail, bulrush, cattail and sedges. Lake Montesian was chemically treated with rotenone in the spring of 1974 to remove a stunted panfish population. It was subsequently restocked with largemouth bass. Northern pike, white suckers and bluegills are also found in the lake. Waterfowl on Lake Montesian include mallards, coots and occasionally Canada geese. Fishing and nonmotorized boating are allowed on the lake and the park provides picnic facilities including a shelter. Fish Species: Largemouth bass, northern pike, white sucker, bluegill.

Natural communities (stream and lake natural communities) represent model results that use predicted flow and temperature based on landscape features and related assumptions. Ranges of flow and temperature associated with specific aquatic life communities (fish, macroinvertebrates) help biologists identify appropriate resource management goals.

This is the most recent date of monitoring data stored in SWIMS. Additional surveys for fish and habitat may be available subsequent to this date.
Trout Waters are represented by Class I, Class II or Class III waters. These classes have specific ecological characteristics and management actions associated with them. For more information regarding Trout Classifications, see the Fisheries Trout Class Webpages.
Wisconsin has designated many of the state's highest quality waters as Outstanding Resource Waters (ORWs) or Exceptional Resource Waters (ERWs). Waters designated as ORW or ERW are surface waters which provide outstanding recreational opportunities, support valuable fisheries and wildlife habitat, have good water quality, and are not significantly impacted by human activities. ORW and ERW status identifies waters that the State of Wisconsin has determined warrant additional protection from the effects of pollution. These designations are intended to meet federal Clean Water Act obligations requiring Wisconsin to adopt an 'antidegradation' policy that is designed to prevent any lowering of water quality - especially in those waters having significant ecological or cultural value.
A water is polluted or 'impaired' if it does not support full use by humans, wildlife, fish and other aquatic life and it is shown that one or more of the pollutant criteria are not met.
The use the water currently supports. This is not a designation or classification; it is based on the current condition of the water. Information in this column is not designed for, and should not be used for, regulatory purposes.
Deep headwater lake describes the depth and location of the lake in a watershed. These variables affect the lakes response to watershed variables.
The use that the investigator believes the water could achieve through managing "controllable" sources. Beaver dams, hydroelectric dams, low gradient streams, and naturally occurring low flows are generally not considered controllable. The attainable use may be the same as the current use or it may be higher.
Fish and Aquatic Life - Default Waters do not have a specific use designation subcategory but are considered fishable, swimmable waters.
This is the water classification legally recognized by NR102 and NR104, Wis. Adm. Code. The classification determines water quality criteria and effluent limits. Waters obtain designated uses through classification procedures.
