This U.S. Geological Survey (USGS) data release presents a digital database of geospatially enabled vector layers and tabular data transcribed from the geologic map of the Lake Owen quadrangle, Albany County, Wyoming, which was originally published as U.S. Geological Survey Geologic Quadrangle Map GQ-1304 (Houston and Orback, 1976). The 7.5-minute Lake Owen quadrangle is located in southeastern Wyoming approximately 25 miles (40 kilometers) southwest of Laramie in the west-central interior of southern Albany County, and covers most of the southern extent of Sheep Mountain, the southeastern extent of Centennial Valley, and a portion of the eastern Medicine Bow Mountains. This relational geodatabase, with georeferenced data layers digitized at the publication scale of 1:24,000, organizes and describes the geologic and structural data covering the quadrangle's approximately 35,954 acres and enables the data for use in spatial analyses and computer cartography. The data types present ...

Navigating the USGS floodplain study reports to confirm WSELs and discharges:Navigate to the location in ArcMap/ArcGIS Pro where you are interested in discharges or Waster Surface Elevations (WSELs)At that location, note the name of the watershed and stream.Go to the USGS floodplain report for the watershed of interest (see below for summary of reports).Go to the list of tables in the USGS report and note the page number for the Water-surface Profile Data table corresponding to the stream or watershed of interest.Go to the relevant Water-surface Profile Data table and locate the section of interest. The station can be easily located by reviewing upstream or downstream roadways or other features noted in the remarks, estimating the distance from the feature on GIS and using stationing information in the second column to locate the section number of interest. The table includes 25-, 50- and 100-year discharges and the corresponding WSELs.WatershedsOpen-File Report#Year completedAccotink Creek76-4421977Cameron Run*76-4431976Pohick Creek76-4441977Difficult Run76-4591976Cub Run78-171978Bull Run, Little Rocky Run, Johnny Moore Creek, and Popes Head Creek77-3291977Bullneck Run, Scott Run, Dead Run, and Pimmit Run78-2601978Horsepen Run, Sugarland Run, Nichlos Run, and Pond Branch78-10281978Occoquan River, Wolf Run, Sandy Run, Elk Horn Run, Giles Run, Kanes Creek, Racoon Creek, and Thompson Creek79-2151978*Excludes Upper Holmes Run and Tripps Run upstream of Lake BarcroftAll open file reports are available from USGS.

DPWES ( Stormwater Planning Division) also maintains copies of the reports.Vertical datum:In 1973, the Sea Level Datum of 1929 was renamed the National Geodetic Vertical Datum of 1929 (NGVD 1929). It appears the USGS reports retained the older name as elevations are referenced to ‘Mean Sea Level’. However, it has always been assumed that this refers to the old Sea Level Datum of 1929 that is now called NGVD 1929. Evaluation of physical changesField data collection for the USGS floodplain studies was completed from about 1960 through 1970. Since physical changes might have occurred in the floodplain after that time, it is important that the area of interest be carefully evaluated to determine if any significant physical changes have occurred. Physical changes typically occur as a result of roadway improvements that significantly alters the stream alignment. Historic (from the 1960’s and 1970s) for the area of interest and current aerial imagery should be used to evaluate this. If physical changes have occurred, the USGS 100-year WSELs are no longer reliable. Use of flow valuesDischarges in the USGS report were computed using the Anderson method which is one of the approved hydrologic methods in the PFM for computing peak flows for drainage areas over 200 acres. The PFM guidance recommends using the USGS flows when available. However, it should be noted that the flow computation points were relatively sparse and flows at a computation point were typically utilized about 3,000-5,000 feet upstream. Therefore the flow at or near the upstream point before a flow change may be relatively conservative.Contact: DPWES GIS ServicesData Accessibility: Publicly AvailableUpdate Frequency: NeverLast Revision Date: 1/29/2024Creation Date: 1/29/2024Feature Dataset Name: N/ALayer Name: STWMGR.USGS_FPL_XSECTIONS

Mine and prospect-related symbols, such as those used to represent prospect pits, mines, adits, dumps, tailings, etc., hereafter referred to as “mine” symbols or features, are currently being digitized on a state-by-state basis from the 7.5-minute (1:24,000-scale) and the 15-minute (1:48,000 and 1:62,500-scale) archive of the USGS Historical Topographic Maps Collection, or acquired from available databases (California and Nevada, 1:24,000-scale only). Compilation of these features is the first phase in capturing accurate locations and general information about features related to mineral resource exploration and extraction across the U.S. To date, the compilation of 637,000-plus point and polygon mine symbols from approximately 88,000 maps across 35 states has been completed: Alabama (AL), Arizona (AZ), Arkansas (AR), California (CA), Colorado (CO), Florida (FL), Georgia (GA), Idaho (ID), Iowa (IA), Illinois (IL), Indiana (IN), Kansas (KS), Kentucky (KY), Louisiana (LA), Michigan (MI), Minnesota (MN), Mississippi (MS), Missouri (MO), Montana (MT), North Carolina (NC), North Dakota (ND), Nebraska (NE), New Mexico (NM), Nevada (NV), Oklahoma (OK), Ohio (OH), Oregon (OR), South Carolina (SC), South Dakota (SD), Tennessee (TN), Texas (TX), Utah (UT), Washington (WA), Wisconsin (WI), and Wyoming (WY). The process renders not only a more complete picture of exploration and mining in the U.S., but an approximate time line of when these activities occurred. The data may be used for land use planning, assessing abandoned mine lands and mine-related environmental impacts, assessing the value of mineral resources from Federal, State and private lands, and mapping mineralized areas and systems for input into the land management process. The data are presented as three groups of layers based on the scale of the source maps. No reconciliation between the data groups was done. Datasets were developed by the U.S. Geological Survey Geology, Geophysics, and Geochemistry Science Center (GGGSC). Compilation work was completed by USGS student contractors: Germán Schmeda, Patrick C. Scott, William Gnesda, Margaret Hammond, Tyler Reyes, Morgan Mullins, Thomas Carroll, Margaret Brantley, and Logan Barrett; and by USGS personnel Damon Bickerstaff, Stuart A. Giles and E.G. Boyce.
