Stream reaches and termini points have been tied to the 1:24k USGS National Hydrography Dataset (NHD). Because of this, termini points may not share the exact lat/long information with the corresponding Water Court decrees. However, they will be accurate to the landmark locations; ie. headwaters of Stream X or confluence of Stream Y and Stream Z. Please refer to the Water Court decrees for official location information.
In some instances, the CWCB staff has noted discrepancies between the decreed legal descriptions of its instream flow water rights and natural lake level filings (i.e., incorrect legal descriptions of upper termini, lower termini, or lake level locations and/or incorrect stream reach lengths). In such instances, the GIS layer represents the CWCB staff's best effort to interpret and represent the true intent of the CWCB at the time it made its appropriation on such streams or lakes.
The CWCB staff intends to update its GIS layers annually to reflect any new appropriations that are made by the CWCB each year and to correct any errors in prior versions of the GIS Layers that might be brought to the staff's attention. Please feel free to notify the CWCB of any apparent errors in the GIS Layer so that the staff can research the apparent error and corrected them if necessary.
