OPINION
Plaintiff-Appellant William Sim Spencer, a Michigan state prisoner proceeding pro se, brought this civil rights action against Defendants-Appellees Michael J. Bouchard, Thomas Quisenberry, Snarey, and Wallace 1 (collectively “the defendants”), all officials with the Oakland County Sheriffs Office. Spencer alleged various claims under the First, Fourth, Eighth, and Fourteenth Amendments. After the magistrate judge recommended granting dismissal or summary judgment to .the defendants on all but one of Spencer’s claims, the district court granted summary judgment on all of them. Spencer’s appeal has been referred to a panel of the court pursuant to Sixth Circuit Rule 34(j)(l). Upon examination, we unanimously agree that oral argument is not needed, fed. R. App. P. 34(a).
Because Spencer has offered sufficient evidence to create a genuine issue of material fact with respect to his Eighth Amendment inadequate-shelter claim against Snarey and Wallace, we REVERSE that part of the district court’s judgment. Because Spencer has failed to satisfy the Prison Litigation Reform Act’s (“PLRA”) administrative exhaustion requirement with respect to his First Amendment claim against Bouchard, Snarey, and Wallace, his Eighth Amendment inadequate-shelter claim against Bouchard, and all claims against Quisenberry, we VACATE that part of the judgment and instruct the district court instead to DISMISS the claims without prejudice. Because Spencer has waived review of all other claims, we AFFIRM the balance of the judgment. We REMAND for proceedings consistent with this opinion.
I. BACKGROUND
Spencer was a pretrial detainee at the Oakland County Jail in Pontiac, Michigan from August 15, 2001 to February 4, 2002. In 2003, Spencer filed an action under 42 U.S.C. § 1983 against several officials in the Oakland County Sheriffs Office, which operates the jail: Sheriff Bouchard, Un-dersheriff Quisenberry, Lieutenant Snar-ey, and Captain Wallace. Spencer alleged that the defendants violated the First Amendment by providing inadequate reading material; the Fourth Amendment by opening his legal mail; the Eighth Amendment by maintaining overcrowded conditions, denying out-of-cell exercise time, and failing to provide adequately warm and dry shelter; and the Fourteenth *724 Amendment by providing inadequate grievance procedures.
The defendants moved for dismissal for failure to state a claim or, in the alternative, summary judgment. 6 Joint Appendix (“J.A.”) at 384-414. The magistrate judge recommended that all claims against Quisenberry and the First Amendment claim against Bouchard, Snarey, and Wallace be dismissed for failure to exhaust the administrative remedies as required by the PLRA. 4 J.A. at 252-54, 260-61 (Report and Recommendation (“R & R”) at 5-7, 13-14). Proceeding to the merits, the magistrate judge recommended that summary judgment be denied with respect to the Eighth Amendment claim for inadequate shelter. 4 J.A. at 258 (R & R at 11). Finally, the magistrate judge recommended the grant of summary judgment with respect to each of the remaining claims. 4 J.A. at 262 (R & R at 15). Spencer filed general objections to the magistrate judge’s adverse recommendations. 7 J.A. at 465-67. The defendants filed an objection to the magistrate judge’s recommendation on the Eighth Amendment inadequate-shelter claim, arguing, inter alia, that they could not be held liable for the failure to act. 7 J.A. at 458-61.
The district court rejected the magistrate judge’s recommendation regarding the Eighth Amendment inadequate-shelter claim and reviewed no other aspect of the magistrate judge’s report. The district court granted summary judgment to the defendants and dismissed the case with prejudice. Spencer now appeals.
II. SCOPE OF THE APPEAL
A. Objections to Magistrate Judge’s Report
At the outset we must determine which, if any, claims to address on appeal. The magistrate judge’s report included a notice requiring objections to be filed within ten days. 4 J.A. at 262 (R & R at 15). A party who receives such notice yet fails timely to object is deemed to waive review of the district court’s adoption of the magistrate judge’s recommendations.
Mattox v. City of Forest Park,
The district court did, however, adopt the rest of the magistrate judge’s report, so we must assess whether Spencer satisfied the objection requirement for his other claims. Spencer filed several objections, the first of which stated that “Plaintiff OBJECTS to the granting of summary judgment in favor of the defendants regarding Plaintiffs overcrowding Claim because the Complaint, Exhibits, Depositions and Affidavits of record support that the relief requested by Plaintiff regarding this issue should be GRANTED.” 7 J.A. at 466. Subsequent objections replaced “overcrowding Claim” with “Cruel and Unusual Punishment/Confinement Claim,” *725 “Due Process Regarding the Grievance Procedure Claim,” and “Fourth Amendment Claims — Legal Mail,” respectively. 7 J.A. at 466-67.
Overly general objections do not satisfy the objection requirement.
Miller v. Currie,
B. PLRA Exhaustion
Having determined that Spencer has preserved certain claims for review, we must next address whether he has satisfied the requirements of the PLRA, which provides that “[n]o action shall be brought with respect to prison conditions under section 1983 of this title, or any other Federal law, by a prisoner confined in any jail, prison, or other correctional facility until such administrative remedies as are available a^e exhausted.” 42 U.S.C. § 1997e(a). The Oakland County Jail provides a two-step grievance procedure in which the inmate first submits a written complaint to the Lieutenant of Corrective Services and then appeals the decision to the Captain of Corrective Services. 2 J.A. at 60. Spencer has attached documents indicating that he followed this procedure. J.A. at 49-51, 57.
Of course, it is not enough simply to follow the grievance procedure; in order to satisfy the administrative exhaustion requirement, the content of the grievances must be adequate, too. First, under our precedent a grievance must identify each defendant eventually sued.
E.g., Curry v. Scott,
One of Spencer’s grievances does, however, name Snarey and Wallace in the context of the Eighth Amendment inadequate-shelter claim. We therefore proceed to the second requirement regarding the content of grievances: “a prisoner must have alleged mistreatment or misconduct on the part of the defendant” in his grievance.
Burton v. Jones,
In describing the alleged mistreatment or misconduct, ... we would not require a prisoner’s grievance to allege a specific legal theory or facts that correspond to all the required elements of a particular legal theory. Rather, it is sufficient for a court to find that a prisoner’s [griev- *726 anee] gave prison officials fair notice of the alleged mistreatment or misconduct that forms the basis of the constitutional or statutory claim made against a defendant in a prisoner’s complaint.
Id.
This relaxed standard is consistent with the general practice of liberally construing pro se prisoners’ filings.
See, e.g., McNeil v. United States,
Our conclusion means that Spencer’s complaint was “mixed,” i.e., it included both exhausted and unexhausted claims. We are therefore confronted with an issue that has recently vexed this court: when a prisoner submits a mixed complaint, do we apply a rule of partial exhaustion that permits his exhausted claims to proceed or a rule of total exhaustion that requires the entire complaint to be dismissed? We faced a similar situation in
Hartsfield v. Vidor,
A panel of this court recently seized upon the implicit nature of this holding in deeming the issue “an open question in this circuit” even after
Hartsfield. Bey v. Johnson,
We note that the Supreme Court has granted certiorari to resolve the partial-/total-exhaustion quandary.
Williams v. Overton,
— U.S. -,
*727 We now proceed to the merits of Spencer’s Eighth Amendment inadequate-shelter claim against Snarey and Wallace.
III. EIGHTH AMENDMENT CLAIM
A. Standard of Review
We review de novo a district court’s grant of summary judgment.
McQueen v. Beecher Cmty. Sch.,
B. Merits
Spencer’s claim is based on the conditions of his pretrial detention. The Eighth Amendment forbids the infliction of “cruel and unusual punishments.” U.S. CONST, amend. VIII. Because the Cruel and Unusual Punishments Clause “is concerned” with punishment by the state “after it has secured a formal adjudication of guilt in accordance with due process of law,”
Ingraham v. Wright,
“It is undisputed that the treatment a prisoner receives in prison and the conditions under which he is confined are subject to scrutiny under the Eighth Amendment.”
Helling v. McKinney,
1. Sufficiently Serious Deprivation
Spencer complains that the state provided inadequate shelter during his pretrial detention by subjecting him to cold, wet conditions. Shelter is, of course, one of the basic needs enumerated in
Farmer,
so the question is whether Spencer’s shelter was constitutionally inadequate. We have held that the Eighth Amendment may be violated when prison officials provide inadequate clothing to inmates required to go outside in the winter.
Knop v. Johnson,
Spencer was detained in cell I-R4 from September 1, 2001 to February 4, 2002, i.e., during the fall and winter. 1 J.A. at 18 (Comp.¶¶ 13, 19); 2 J.A. at 112-13 (Wilhelm Dep.¶ 6). For more than ninety days of this period, he had to sleep on a mattress on the floor due to overcrowding. 1 J.A. at 20 (Compl.¶ 34); 2 J.A. at 115 (Wilhelm Dep.¶ 21). Spencer’s cell block was “very cold,” prompting the complaints of other inmates. 2 J.A. at 115 (Wilhelm Dep. ¶¶ 12, 18). It was particularly cold at the end of the cell block where Spencer’s cell was located. 2 J.A. at 115 (Wilhelm Dep. ¶ 20). Although it was cold enough for the officers to wear their winter coats indoors, Spencer and the other inmates were dressed only in their standard jumpsuits. 1 J.A. at 20 (Compl.¶ 40), 35 (Spencer Aff. ¶ 25). Worse yet, whenever it rained or snowed, water leaked “real bad” through the ceiling above Spencer’s mattress. 2 J.A. at 115 (Wilhelm Dep. ¶ 22). The leaks caused the area where Spencer slept to be flooded. 1 J.A. at 20 (ComplA 35), 42 (Spencer Aff. ¶ 57).
Although Spencer’s evidence is sufficient to conclude that it was cold inside his1-cell, there is some question as to just how cold it was.
4
We observe, however, that Spencer’s evidence is also sufficient to conclude that he lived in cold temperatures
continuously for several months
(including all of December and January), subject only to the occasional relief of an unseasonably warm day. By way of comparison, the
*729
Knop
inmates experienced more direct contact with the cold when they were forced to go outdoors without adequate clothing, but this exposure obviously was not continuous; and Franklin was continuously exposed to “close to freezing” temperatures inside his cell, but for “only” twenty-two days.
Franklin,
2. Deliberate Indifference
The deliberate-indifference requirement is satisfied “only if [the official] knows that inmates face a substantial risk of serious harm and disregards that risk by failing to take reasonable measures to abate it.”
Farmer,
We need not rely solely on the obviousness of the risk, however, because Spencer has offered much evidence in support of the deliberate-indifference element. Snar-ey and Wallace were among the officers seen wearing their winter coats indoors. 1 J.A. at 20 (Comply 40), 35 (Spencer Aff. ¶ 25). They also personally received complaints about the cold, wet conditions from Spencer and other inmates. 2 J.A. at 114, 115-16 (Wilhelm Dep. ¶¶ 12, 23-26). Therefore, Snarey and Wallace obviously knew “that inmates face[d] a substantial risk of serious harm.”
Farmer,
***
The defendants press only one argument in urging us to affirm the district court on this claim: “supervisory liability under § 1983 cannot be based on a mere failure to act.” Appellee Br. at 17. This proposition is, of course, true.
See, e.g., Combs v. Wilkinson,
The phrase “failure to act” has a lay meaning; colloquially, a “failure to act” is an omission. Yet the phrase is also a legal term of art that means the absence of state action, which is required for most constitutional claims. A colloquial “failure to act” (i.e., an omission) often will translate into a legal “failure to act” (i.e., the absence of the element of state action). This equivalence is precisely what the defendants are attempting to establish. According to the defendants, they colloquially failed to act by not addressing the jail’s wet, cold conditions, so they also legally failed to act and therefore are not liable.
What the defendants miss, however, is that in the prison context, an omission often
is
state action, which means that a colloquial “failure to act” often is
not
a legal “failure to act.” As the Supreme Court has explained, “when the State by the affirmative exercise of its power so restrains an individual’s liberty that it renders him unable to care for himself, and at the same time
fails to provide
for his basic human
needs
— e.g., food, clothing, shelter, medical care, and reasonable safety — it transgresses the substantive limits on
state action
set by the Eighth Amendment and the Due Process Clause.”
DeShaney v. Winnebago County Dep’t of Social Servs.,
IV. CONCLUSION
For the reasons set forth above, we REVERSE in part, VACATE in part, and AFFIRM in part the district court’s order granting summary judgment to the defendants and REMAND for proceedings consistent with this opinion.
Notes
. The full names of Snarey and Wallace are not in the record.
. We have on occasion spoken in terms of the Amendment itself (rather than simply the Clause) not applying to pretrial detainees.
See, e.g., Barber v. City of Salem,
. Federal pretrial detainees are similarly protected by the Fifth Amendment's Due Process Clause.
Daniels v. Woodside,
. Spencer alleges that ice formed on the walls, 1 J.A. at 20 (Compl.¶ 41), but his complaint was not verified and he has offered no evidence to support this allegation.
. A failure to act also does not give rise to § 1983 liability for state-created-danger claims,
see, e.g., Cartwright v. City of Marine City,
.
Farmer
itself involved a quintessential failure to act: the "failure to prevent harm.”
