conditionPublicationPolicy=static-value-structural-unavailable. Coralville Lake is the Iowa City-metro USACE Iowa River reservoir with destination-specific Fish Iowa COR52 fishery for catfish and big-crappie potential plus documented public access. inlandHasCompleteStaticFisheryValue passes on official Iowa DNR fishery, access, and regulations. No same-lake live USGS 00010 exists; Cedar River 05465000 is a separate river and Lake Macbride is a different physical waterbody. No new Estimated science is introduced. HIGH plus PATH B does not auto-approve; public catalog-visible Unavailable is approved because Coralville is the eastern Iowa federal-reservoir class, not Saylorville and not Macbride. This justification is Coralville-specific and does not copy Saylorville or Rathbun prose.
