Fishery overview
Lake Francis Case is the distinct Fort Randall Dam Missouri River reservoir between Big Bend Dam and Gavins Point Dam. StrikeTracks publishes complete static Fishery with catalog-visible Unavailable conditions because no qualifying same-lake live USGS 00010 exists. Tailwater temperature below Fort Randall does not represent this pool. This is not Lake Sharpe and not Lewis and Clark Lake.

South Dakota fishing license required. GFP Missouri River fishing exceptions apply on Lake Francis Case, including any posted seasonal closures that are harvest rules, not condition science. Distinct from Lewis and Clark / Gavins Point pool rules. Confirm current GFP Missouri River regulations.
conditionPublicationPolicy=static-value-structural-unavailable. Lake Francis Case is the distinct Fort Randall Dam Missouri River reservoir named by GFP as a separate Missouri-system fishery from Sharpe and Lewis and Clark, with destination-specific USACE Fort Randall recreation and GFP Missouri River regulations. inlandHasCompleteStaticFisheryValue passes on official GFP fishery, access, and regulations. No qualifying same-lake live USGS 00010 exists; Fort Randall tailwater, stage, elevation/storage, and Big Bend pool temperature are not accepted lake Monitoring or Estimated science. Seasonal closures are harvest rules, not thermal science. HIGH plus PATH B does not bulk-approve the four Missouri reservoirs; public catalog-visible Unavailable is approved because Francis Case has independent customer identity as the Fort Randall pool, and honest Unavailable plus complete static Fishery is independently useful from Sharpe and Lewis and Clark. This justification is Francis Case-specific and does not copy Sharpe or Lewis and Clark prose.
