Immediately west of Lewiston is the smaller twin city of [[Clarkston, Washington]]. The north-flowing Snake River departs [[Hells Canyon]] and forms the state boundary with [[Washington (state)|Washington]], while west-flowing Clearwater River defines the northern border of the city. At their confluence at the city's northwest corner, the lower Snake River turns west into Washington, and after passing four dams, empties into the [[Columbia River]] at [[Burbank, Washington|Burbank]]. About {{convert|30|mi|-1|spell=In}} northwest of the city is the [[Lower Granite Dam]], the last and upper-most of the four dams on the lower Snake River. It was completed {{Time ago|1975}} in 1975,<ref name=dedand>{{cite news |url=https://news.google.com/newspapers?id=zcReAAAAIBAJ&sjid=1zEMAAAAIBAJ&pg=4068%2C5388144 |newspaper=Lewiston Morning Tribune |last=Harrell |first=Sylvia |title=Dedication: Andrus brings a warning |date=June 20, 1975 |page=1 |access-date=October 18, 2019 |archive-url=https://web.archive.org/web/20170511041032/https://news.google.com/newspapers?id=zcReAAAAIBAJ&sjid=1zEMAAAAIBAJ&pg=4068%2C5388144 |archive-date=May 11, 2017 |url-status=live }}</ref> creating a reservoir, [[Lower Granite Lake]] that stretches to Lewiston. According to the [[United States Census Bureau|U.S. Census Bureau]], the city has a total area of {{convert|18.04|sqmi|sqkm|2}}, of which {{convert|17.23|sqmi|sqkm|2}} is land and {{convert|0.81|sqmi|sqkm|2}} is water.<ref name="Gazetteer files">{{cite web|title=US Gazetteer files 2010|url=https://www.census.gov/geo/www/gazetteer/files/Gaz_places_national.txt |publisher=[[United States Census Bureau]] |access-date=2012-12-18 |url-status=dead |archive-url=https://web.archive.org/web/20120125061959/http://www.census.gov/geo/www/gazetteer/files/Gaz_places_national.txt |archive-date=2012-01-25 }}</ref> Downtown Lewiston, at elevations between {{convert|740|ft}} and {{convert|780|ft}}, is only slightly higher in [[elevation]] than the river, about {{convert|741|ft|0|abbr=on}}, which was {{convert|30|ft|0|spell=in}} lower prior to the completion of the [[Lower Granite Dam]]. Away from downtown the terrain gains elevation quickly, as the steep riverbank highway of [[U.S. Route 95 in Idaho|U.S. 95]] north of Lewiston ascends to {{convert|2756|ft}}. The [[List of U.S. states by elevation|lowest point]] in the state of Idaho is located on the Snake River in Lewiston, where it meets the Clearwater and flows west into Washington. The populated areas in Idaho with the lowest elevations are along (or near) the Clearwater River, from [[Lowell, Idaho|Lowell]] at {{convert|1486|ft}} to Lewiston. === The Orchards === [[File:ThainGradeLewistonIdahoCirca2002.jpg|thumb|Traffic heading down "Thain Grade" in 2002.

[[Lewiston Hill]] can be seen on the opposite side of the [[Clearwater River (Idaho)|Clearwater River]] and around the bend of the [[Snake River]].]] The heavily residential southern half of the city is referred to as "The Orchards". This area is much higher in elevation than downtown, at about {{convert|1400|ft||round=5|abbr=on}}, and is named for the [[fruit orchard]]s that previously covered the area.

There is little sign of any orchards today, although there is a wide proliferation of fruit trees in the backyards of many residences in this area of town. The [[Lewiston-Nez Perce County Airport]] is located on the western edge of the Orchards plateau at {{convert|1438|ft}} above sea level, with Bryden Canyon Road providing westbound access via the [[Southway Bridge]] into Clarkston. ===Climate=== Lewiston experiences a [[semi-arid climate]] ([[Köppen climate classification|Köppen]] ''BSk'') with occasionally cold, but short, winters, mostly influenced by mild Pacific air, and hot, dry summers. The monthly daily average temperature ranges from {{convert|35.2|°F|1}} in December to {{convert|75.8|°F|1}} in July; the temperature reaches {{convert|100|°F|0}} on 7.7 afternoons, {{convert|90|°F|0}} on 42 afternoons, and does not rise above freezing on 14 afternoons annually. The last year that Lewiston did not reach {{convert|100|°F|1}} was back in 1995.<ref name= "NWS Spokane, WA">{{cite web |url = https://w2.weather.gov/climate/xmacis.php?wfo=otx |title = NowData - NOAA Online Weather Data |publisher = [[National Oceanic and Atmospheric Administration]] |access-date = 2019-08-31 |archive-url = https://web.archive.org/web/20190402004000/https://w2.weather.gov/climate/xmacis.php?wfo=otx |archive-date = 2019-04-02 |url-status = live }}</ref> Precipitation averages {{convert|12.31|in|cm|0}} annually, including an average seasonal snowfall of {{convert|10.5|in|cm|0}}.<ref name= "NWS Spokane, WA"/> At 195 days, the growing season is relatively long, with the average window for freezing temperatures being October 23 thru April 10.<ref name= "NWS Spokane, WA"/> The plant [[hardiness zone]] of Lewiston is 7b with some pockets of 8a.
