| Abstract | This layer shows legally designated trout lakes as identified in Minnesota Rules Chapter 6264. These are inland lakes managed by DNR Fisheries for trout species (not including lake trout). In order to protect and foster the propagation of trout, several restrictions on fishing in these lakes apply. See http://www.revisor.leg.state.mn.us/arule/6264/0050.html for legal descriptions and restrictions associated with designated trout waters. |
| Use Tips | This data layer is a subset of the DNR 100K water (hydrography) layer, a statewide data set originally derived from USGS DLG 100K data and updated to better reflect Fisheries-managed basins. Lake basin polygons have been merged together (dissolved by DOW#) to form one polygon per lake name. Users are encouraged to use the full resolution DNR 100K hydrography or DNR 100K Lakes and Rivers layers as a base layer to visualize all lakes and fully understand hydrological connectivity, watershed position and spatial relationships to designated trout lake resources. |

| Attribute Accuracy | Source table LAKE_DNRPY2.DBF: The bulk of the attributes are derived from the USGS DLG source, although for lakes with DOW Lake Numbers, the attributes have been reviewed by DNR Fisheries Staff. | |||
| Logical Consistency | ||||
| Completeness | Complete statewide | |||
| Horizontal Positional Accuracy | Source layer hydro_source_100kpy2: Horizontal positional accuracy is based originally on 100k USGS source quadrangles, and has been improved by on-screen digitizing over USGS 1991-1992 DOQ imagery. | |||
| Vertical Positional Accuracy | Source layer hydro_source_100kpy2: Not Applicable | |||
| Lineage | Attribute Lineage for source table LAKE_DNRPY2.DBF: Attributes began with USGS DLG source data and in 2003-2004 were reviewed and updated where possible by DNR Fisheries GIS staff. | |||

| Entity and Attribute Overview | Data Elements for Attribute Table LAKE_DNRPY2.DBF: LAKE_NAME: Lake Name per Division of Waters LKDBMAIN database DOWLKNUM: DNR Division of Waters lake ID number DOW_VERIF: A flag to identify records whose DOW numbers have been validated. For the most part, only those lakes whose DOW numbers are listed in the DNR Fisheries Lake Survey Database (meaning the lake has been surveyed at least once) have been validated. ALT_NAME: Alternate lake name per Division of Waters LKDBMAIN database LAKE_CLASS: This field holds DNR Fisheries Lake Class information. The Section of Fisheries has developed an ecological classification system for Minnesota's lakes based on the analysis of historical survey records. Using data from approximately 8,000 surveys from more than 3,500 lakes, fisheries research biologist Denny Schupp, developed mathematical models that classified lakes into 43 distinct groups. Variables used to develop the models include: lake area, maximum depth, percent littoral area, total alkalinity, secchi disc transparency, shoreline development factor, morphoedaphic index, and Carlson's Trophic status index. Characteristic fish communities were then described for each lake class by analyzing historical gill net and trap net data. Fisheries managers use this information to evaluate fish population status, determine the effectiveness of various management actions, and to establish realistic fisheries management goals and objectives. The methodology and documentation of this classification system is found in An Ecological Classification of Minnesota Lakes With Associated Fish Communities, by Dennis H. Schupp. 1992. Investigational Report No. 417, Minnesota Department of Natural Resources, Section of Fisheries, St. Paul, MN REDIG_SRC: Photo imagery source for redigitizing of water polygon features. USCLASS: Field that stores the hydrologic feature type, as per the original USGS DLG classification. Code definitions have been expanded by DNR Fisheries, and some features have been re-classified to better reflect current hydrographic conditions. MAIN_DOW: The primary DOWLKNUM for a lake (the MAIN DOW number ends in ''''00''''). Some lakes are split into sub-basins for management or study purposes. In this case, sub-basin IDs are assigned; (the DOWLKNUM number will end in ''''01'''', ''''02,'''' etc.) |
